A wireless communication method provided by the embodiments of the present disclosure includes the following operation.


A terminal device receives first configuration information transmitted by a network device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


A wireless communication apparatus provided by the embodiments of the present disclosure includes a transceiver.


The transceiver is configured to receive first configuration information transmitted by a network device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


A wireless communication apparatus provided by the embodiments of the present disclosure includes a transceiver.


The transceiver is configured to transmit first configuration information to a terminal device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


According to the above technical solutions, the network device indicates, through the first configuration information, the first time domain resource that includes the first frequency domain part in frequency domain, and for any one time unit in the first time domain resource, the transmission direction of the first frequency domain part configured by the first configuration information is able to be different from the transmission direction for the time unit configured by the second configuration information. In this way, different transmission directions can be supported for different frequency domain resources within one time unit, so that configuration of the frequency domain resources in different transmission directions can be implemented in one time unit. Moreover, one time unit can include, in frequency domain, frequency domain resources with different transmission directions, and thus the reception and transmission of data can be performed simultaneously in one time unit, thereby improving resource utilization.

FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the present disclosure.


As illustrated in FIG. 1, the communication system 100 may include terminal devices 110 and a network device 120. The network device 120 may communicate with the terminal devices 110 through an air interface. Multi-service transmission is supported between the terminal devices 110 and the network device 120.


It should be understood that the embodiments of the present disclosure are only illustrated with reference to the communication system 100, but the embodiments of the present disclosure are not limited thereto.

Uplink-Downlink Configuration

For the TDD system, the uplink-downlink-configuration is used to configure/indicate the transmission direction of each symbol. In the related art, it is mentioned that one or more of three modes of TDD-uplink-downlink common configuration (TDD-UL-DL-ConfigCommon), TDD-uplink-downlink dedicated configuration (TDD-UL-DL-ConfigDedicated) and Slot Format Indication (SFI) are used to indicate the transmission direction of each symbol, and there are three types of transmission directions of symbol including uplink, downlink and a flexible transmission direction. The TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are higher-layer signaling, where the former is configured for a cell and is transmitted to all users in the cell through broadcast information, and the latter is independently transmitted to users who need it through RRC signaling.

The SFI indicates the transmission direction of each slot/symbol in each carrier through Downlink Control Information (DCI) (which may also be referred to as a group common DCI) of a user group: DCI format 2_0. Since SFI is a dynamic signaling, it may indicate a semi-statically configured slot/symbol as a determined transmission direction, i.e., uplink or downlink.


In order to improve resource utilization, X Division Duplexing (XDD) technology is introduced, where the transmission and reception of data can be performed simultaneously on different subbands of the same subframe. As illustrated in FIG. 2A, a middle subband of one downlink (DL) slot is configured to be an uplink (UL) subband. As illustrated in FIG. 2B, a part of subbands of one DL slot is configured to be an UL subband. The uplink subbands in FIG. 2A and FIG. 2B may also be referred to as uplink parts. The XDD is mainly used on the base station side. The terminal side still maintains the current state, that is, only transmission or reception of data is supported in one subframe. The slot or symbol where reception and transmission of data can be performed simultaneously based on different subbands may be referred to as a slot/symbol supporting subband Full Duplex (SBFD) or Subband non-Overlapping Full Duplex (SBFD).


Regarding SBFD, at the 3GPP RAN related meeting, the following agreements were made.


A semi-static configuration is mainly adopted for the indication of the position of the SBFD subband.


For the indication of the position of the SBFD subband, i.e., the SBFD configuration, a semi-static configuration is considered preferentially, or even only a semi-static configuration may be adopted.


In addition, the semi-static configuration is adopted for the time domain position of the SBFD, but a dynamic configuration is already supported by the TDD frame structure. The configured results from the two configurations may be different, resulting in a conflict between the configured results, for example, a slot/symbol configured with the SBFD is dynamically indicated as an uplink slot/symbol simultaneously. In addition, for a flexible slot/symbol, when it is configured with an uplink part, that is, an uplink subband, whether it is considered as an SBFD slot/symbol or an uplink slot/symbol is a problem.


In order to facilitate understanding of the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be described in detail below with reference to specific embodiments. The above related arts may be arbitrarily combined with the technical solutions of the embodiments of the present disclosure as optional solutions, and all of them belong to the scope of protection of the embodiments of the present disclosure. Embodiments of the present disclosure include at least some of the following contents.


An optional processing flow of the wireless communication method provided by an embodiment of the present disclosure is applied to a terminal device. As illustrated in FIG. 3, the method includes the following operation S301.


In operation S301, the terminal device receives first configuration information transmitted by a network device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each of time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


An optional processing flow of the wireless communication method provided by an embodiment of the present disclosure is applied to a network device. As illustrated in FIG. 4, the method includes the following operation S401.


In operation S401, the network device transmits first configuration information to a terminal device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


An optional processing flow of the wireless communication method provided by an embodiment of the present disclosure is applied to a wireless communication system including a network device and a terminal device. As illustrated in FIG. 5, the method includes the following operation S501.


In operation S501, the network device transmits the first configuration information to the terminal device.


The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each of which includes the first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by the second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


Hereinafter, the wireless communication methods illustrated in FIG. 3, FIG. 4, and FIG. 5 will be described.


The first configuration information is used to indicate the first time domain resource. In frequency domain, each of the one or more time units of the first time domain resource includes the first frequency domain part. The first frequency domain part may be understood as a part of subbands of one time unit. It may be understood that the first configuration information indicates a time unit including the first frequency domain part in the frequency domain, and the time unit indicated by the first configuration information constitutes the first frequency domain resource.


In an example, each of the slot A and the slot B includes the first frequency domain part in frequency domain, the first configuration information transmitted by the network device indicates the slot A and the slot B, and the terminal device determines that each of the slot A and the slot B includes the first frequency domain part in frequency domain based on the received first configuration information.


In some embodiments, the first configuration information is used to indicate the first frequency domain part and the first time domain resource, and the terminal device determines that each of the one or more time units included in the first time domain resource includes the first frequency domain part in frequency domain.


In some embodiments, the first frequency domain part is less than or equal to a reception bandwidth or a transmission bandwidth supported by the terminal device, in the frequency domain.


In some embodiments, the first frequency domain part is less than or equal to a bandwidth of a Bandwidth Part (BWP) supported by the terminal device, in the frequency domain.


In some embodiments, the first frequency domain part is used for uplink transmission or downlink transmission.


It may be understood that, for a time unit in the first time domain resource, the first configuration information is used to configure a transmission direction of the first frequency domain part, and the transmission direction of the second frequency domain part, which is a frequency domain part other than the first frequency domain part, is different from the transmission direction of the first frequency domain part.


The first frequency domain part for uplink transmission may be referred to as an uplink part, and the first frequency domain part for downlink transmission may be referred to as a downlink part. If the first frequency domain part is used for uplink transmission, then the transmission direction of the first frequency domain part is uplink. If the first frequency domain part is used for downlink transmission, then the transmission direction of the first frequency domain part is downlink. In the embodiments of the present disclosure, the first frequency domain part on one time unit in the first frequency domain resource is used for uplink transmission or downlink transmission, and the transmission directions of the first frequency domain parts included in different time units are the same or different. The first time domain resources including the first frequency domain parts with different transmission directions may be indicated by different first configuration information.


In an example, when the first configuration information indicates that the time units 1 to 4 include uplink parts in the frequency domain, the first time domain resource includes the time units 1 to 4.


In an example, when the first configuration information indicates that the time units 5 to 7 include downlink parts in the frequency domain, the first time domain resource includes the time units 5 to 7.


In an example, the terminal device receives two pieces of first configuration information: first configuration information A and first configuration information B. The first configuration information A indicates that the time units 1 to 4 include uplink parts in the frequency domain, and the first configuration information B indicates that the time units 5 to 7 include downlink parts in the frequency domain. In this case, the first time domain resource includes the time units 1 to 7.


The second configuration information is used to configure the transmission directions of respective time units in one period. For one time unit, the transmission direction configured by the second configuration information may include one of uplink, downlink, and a flexible transmission direction. It may be understood that, for one time unit, the second configuration information is used to configure the transmission direction for the time unit, which may be understood that the transmission direction of the entire frequency domain of the time unit is the transmission direction of the time unit configured by the second configuration information.


For any one time unit on the first time domain resource, the transmission direction of the first frequency domain part may be different from the transmission direction configured by the second configuration information.


For a time unit including the first frequency domain part, the transmission direction of the first frequency domain part is the same as or different from the transmission direction of the time unit configured by the second configuration information.


If the transmission direction of the first frequency domain part is uplink, for a time unit including the first frequency domain part, the transmission direction of the time unit may be configured to be uplink, downlink, or flexible by the second configuration information.


If the transmission direction of the first frequency domain part is downlink, for a time unit including the first frequency domain part, the transmission direction of the time unit may be configured to be uplink, downlink, or flexible by the second configuration information.


In an example, for a time unit including the first frequency domain part, the transmission direction of the first frequency domain part is uplink, and the transmission direction of the time unit configured by the second configuration information is downlink. In one example, for a time unit including the first frequency domain part, the transmission direction of the first frequency domain part is downlink, and the transmission direction of the time unit configured by the second configuration information is flexible. In an example, for a time unit including the first frequency domain part, the transmission direction of the first frequency domain part is downlink, and the transmission direction of the time unit configured by the second configuration information is uplink.


In some embodiments, the second configuration information includes at least one of: TDD-UL-DL-ConfigCommon, TDD-UL-DL-ConfigDedicated, or SFI.


The TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are used to semi-statically configure the transmission directions of the time units in one period, and the SFI is used to dynamically configure the time units in one period, for which the transmission direction is configured to be flexible by the TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated.


The transmission direction of a time unit may be configured only semi-statically, or may be configured dynamically on the basis of being configured semi-statically.


Taking the transmission direction of a time unit being configured only semi-statically as an example, the transmission direction of a time unit may be configured to be uplink through an Information Element (IE), such as TDD-UL-DL-ConfigCommon, in higher layer signaling (such as Radio Resource Control (RRC) signaling), or the transmission direction of a time unit may be configured to be downlink through TDD-UL-DL-ConfigDedicated.


Taking the transmission direction of a time unit being configured dynamically on the basis of being configured semi-statically as an example, for a time unit for which the transmission direction is configured to be uplink by the second configuration information, the transmission direction of the time unit may be semi-statically configured to be uplink through TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated, or may be dynamically configured to be uplink according to SFI in a case that the transmission direction is semi-statically configured to be flexible through TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated.


In the embodiments of the present disclosure, the time unit includes a time unit in a time domain such as a second, a frame, a subframe, a slot, a sub-slot, or a symbol.


In the embodiments of the present disclosure, the network device may transmit the first configuration information and the second configuration information respectively at different moments. It may be understood that the terminal device may receive the first configuration information and the second configuration information respectively at different moments.


In some embodiments, the network device firstly transmits the first configuration information, and then transmits the second configuration information to the terminal device after transmitting the first configuration information for a certain period of time. In this case, the terminal device firstly receives the first configuration information, and then receives the second configuration information transmitted by the network device after a certain period of time. In some embodiments, the network device firstly transmits the second configuration information, and then transmits the first configuration information to the terminal device after transmitting the second configuration information for a certain period of time. In this case, the terminal device firstly receives the second configuration information, and then receives the first configuration information transmitted by the network device after a certain period of time.


In some embodiments, the first configuration information is used to indicate at least one of:

    • the first indication content: whether each time unit within the first period belonging to the first time domain resource;
    • the second indication content: the first number, where the first time domain resource includes the first number of time units in the first period; or
    • the third indication content: the first position and the first number, where the first time domain resource includes the first number of time units in the first period that use the first position as a starting position or an ending position.


The first time domain resource includes time units within the first period, each of which includes, in frequency domain, the first frequency domain part. The first configuration information indicating the first time domain resource may be understood as indicating a time unit(s) included in the first frequency domain resource.


For the first indication content, the first configuration information indicates whether each of time units within the first period belongs to the first time domain resource.


In some embodiments, whether each of time units within the first period belongs to the first time domain resource may be indicated in a manner of bitmap.


For a time unit in the first period, whether the time unit belongs to the first time domain resource is determined based on a value of a bit corresponding to the time unit. In an example, a value 1 of a bit is 1, indicating that the time unit identified by the bit belongs to the first time domain resource, and a value of a bit is 0, indicating that the time unit identified by the bit does not belong to the first time domain resource.


Taking the value 1 indicating that the time unit belongs to the first time domain resource and the value 0 indicating that the time unit does not belong to the first time domain resource for example, in an example, the first period includes 10 slots, and the first configuration information includes 0011111100. As a result, the second to eighth slots among the 10 slots belong to the first time domain resource.


For the second indication content, the first number is the number of time units included in the first period in the first time domain resource.


For the second indication content, after determining the first number based on the first configuration information, the terminal device determines the first time domain resource based on a preset position and the first number.


If the first frequency domain part is used for uplink transmission, the first number of time units ends at a preset position. It may be understood that the preset position is the last time unit included in the first frequency domain resource. In some embodiments, the preset position includes a previous time unit of the first time unit configured to be uplink by the second configuration information within the first period, or a last time unit within the first period.


Taking the preset position being a previous time unit of the first time unit configured to be uplink (i.e., uplink time unit) by the second configuration information within the first period as an example, the first period includes 10 slots, and the transmission directions of the 10 slots configured by the second configuration information are illustrated in FIG. 6. The transmission directions of the first and second slots are downlink (identified as D), the transmission directions of the third to eighth slots are flexible (identified as F), and the transmission directions of the ninth to tenth slots are uplink (identified as U). In this case, the last slot including the uplink part is the eighth slot. When the first number indicated by the first configuration information is 5, the fourth to eighth slots include the uplink parts.


Taking the preset position being the last time unit within the first period as an example, the first period includes 10 slots, and the transmission directions of the 10 slots configured by the second configuration information are illustrated in FIG. 6. The transmission directions of the first and second slots are downlink (identified as D), the transmission directions of the third to eighth slots are flexible (identified as F), and the transmission directions of the ninth to tenth slots are uplink (identified as U). In this case, the last slot including the uplink part is the tenth slot. When the first number indicated by the first configuration information is 5, the sixth to tenth slots include the uplink parts.


If the first frequency domain part is used for downlink transmission, the first number of time units starts from a preset position. It may be understood that the time unit at the preset position is the first time unit included in the first frequency domain resource.


In an example, the preset position includes the first time unit within the first period or a next time unit after the last time unit configured to be downlink by the second configuration information.


Taking the preset position being the first time unit within the first period as an example, the first period includes 10 slots, and the transmission directions of the 10 slots configured by the second configuration information are illustrated in FIG. 6. In this case, the first slot including the downlink part is the first slot. When the first number indicated by the first configuration information is 5, the first to fifth slots include the downlink parts.


Taking the preset position being a next time unit after the last time unit configured to be downlink by the second configuration information in the first period as an example, the first period includes 10 slots, and the transmission directions of the 10 slots configured by the second configuration information are illustrated in FIG. 6. In this case, the first slot including the downlink part is the third slot. When the first number indicated by the first configuration information is 5, the third to seventh slots include the downlink parts.


For the third indication content, the first configuration information indicates the first position in addition to the first number, and the first position and the first number are used to determine the first time domain resource. In some embodiments, the first position may be a position of the first or last time unit in the first time domain resource.


The first position is a starting position or an ending position of the first time domain resource in the first period. The first position being the starting position of the first time domain resource may be understood to be that the first position indicates the first time unit of the first time domain resource in the first period. The first position being the ending position of the first time domain resource may be understood to be that the first position indicates the last time unit of the first time domain resource in the first period.


Taking the first position being the starting position of the first time domain resource as an example, the first period includes 10 slots. When the first position indicated by the first configuration information is 2, and the first number indicated by the first configuration information is 5, the second to sixth slots include the first frequency domain parts.


Taking the first position being the ending position of the first time domain resource as an example, the first period includes 10 slots. When the first position indicated by the first configuration information is 8, and the first number indicated by the first configuration information is 5, the fourth to eighth slots include the first frequency domain parts.

If at least two periods are configured by the second configuration information, the first period is determined based on the at least two periods configured by the second configuration information. In some embodiments, the first period is a sum of the at least two periods configured by the second configuration information.

In some embodiments, a transmission mode of a target time unit belonging to the first time domain resource includes one of the following:

    • entire frequency domain resource of the target time unit being used for uplink transmission as a whole;
    • entire frequency domain resource of the target time unit being used for downlink transmission as a whole; and
    • a transmission mode of the first frequency domain part of the target time unit being independent of a transmission mode of the second frequency domain part of the target time unit. The second frequency domain part is a frequency domain part of the target time unit other than the first frequency domain part.


Here, the target time unit is any one time unit in the first time domain resource. The transmission mode of the target time unit may be understood as at least one of the following:

    • a transmission direction of the target time unit;
    • whether the frequency domain resource of the target time unit being scheduled for transmission; or
    • when the target time unit is scheduled for transmission, resource configuration information for determining a transmission resource for transmission in the target time unit, i.e., a transmission configuration. The resource configuration information includes at least one of: position information for determining a position of a frequency domain transmission resource, a Modulation and Coding Scheme (MCS), and the like.


In some embodiments, the target time unit may be dynamically scheduled for uplink transmission or downlink transmission by higher layer signaling, such as RRC signaling.


Taking the entire frequency domain of the target time unit as a whole as an example, when the entire frequency domain of the target time unit is used for uplink transmission or downlink transmission, and the first frequency domain part and the second frequency domain part have at least one of the following features.


There is only one transmission direction for the whole frequency domain of the target time unit, that is, the transmission directions of the first frequency domain part and the second frequency domain part are the same.


The entire frequency domain of the target time unit is scheduled as a whole.


One piece of resource configuration information is used by the target time unit as a whole to determine the transmission resource.


If the entire frequency domain resource of the target time unit is used for uplink transmission as a whole, the transmission direction of the target time unit is uplink and includes only uplink, the entire frequency domain resource of the target time unit is scheduled as a whole, and one piece of uplink resource configuration information is used to determine the uplink transmission resource for uplink transmission. In this case, the uplink transmission may be scheduled on the entire BWP bandwidth of the target time unit.


If the entire frequency domain resource of the target time unit is used for downlink transmission as a whole, the transmission direction of the target time unit is downlink and includes only downlink, the entire frequency domain resource of the target time unit is scheduled as a whole, and one piece of downlink resource configuration information is used to determine the transmission resource for downlink transmission. In this case, the downlink transmission may be scheduled on the entire BWP bandwidth of the target time unit.


Taking the transmission mode of the first frequency domain part of the target time unit being independent of the transmission mode of the second frequency domain part of the target time unit as an example, the target time unit is used for uplink transmission or downlink transmission, the uplink transmission and the downlink transmission do not overlap in the frequency domain, and the first frequency domain part and the second frequency domain part have at least one of the following features.

If the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the transmission direction of the first frequency domain part and the transmission direction of the second frequency domain part may be the same or different.


If the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the transmission direction of the second frequency domain part includes one of the following: uplink, downlink, or a flexible transmission direction.


Taking the transmission mode of the first frequency domain part being independent of the transmission mode of the second frequency domain part for example, in an example, when the first frequency domain part of the target time unit is used for uplink transmission, and the transmission direction of the second frequency domain part is uplink, the first frequency domain part and the second frequency domain part are both used for uplink transmission, and the first frequency domain part and the second frequency domain part are independently scheduled.


Taking the transmission mode of the first frequency domain part being independent of the transmission mode of the second frequency domain part for example, in an example, when the first frequency domain part of the target time unit is used for uplink transmission, and the transmission direction of the second frequency domain part is downlink or flexible, the first frequency domain part and the second frequency domain part are independently scheduled, and the downlink transmission is performed only in the first frequency domain part.


Taking the transmission mode of the first frequency domain part being independent of the transmission mode of the second frequency domain part for example, in an example, when the first frequency domain part of the target time unit is used for downlink transmission, and the transmission direction of the second frequency domain part is uplink or flexible, the first frequency domain part and the second frequency domain part are independently scheduled, and the uplink transmission is performed only in the first frequency domain part.

The second solution is that the transmission mode of the target time unit is determined based on the first configuration information and the second configuration information.


The third solution is that the transmission direction configured by the second configuration information is limited.


In the embodiment of the present disclosure, when the transmission direction of the target transmission unit is simultaneously configured by the first configuration information and the second configuration information, there is a case where the transmission direction configured by the first configuration information conflicts with the transmission direction configured by the second configuration information. Through any one of the above first to third solutions, the problem that for a time unit, the transmission direction configured by the first configuration information conflicts with the transmission direction configured by the second configuration information can be solved.


In the first solution, the transmission mode of the target time unit is determined based on the first configuration information.


In some embodiments, the transmission mode of the first frequency domain part of the target time unit is independent of the transmission mode of the second frequency domain part of the target time unit.


Taking the first frequency domain part being used for uplink transmission as an example, the transmission direction of the first frequency domain part of the target time unit is uplink, the uplink transmission on the target time unit is performed in the first frequency domain part, and the downlink transmission on the target time unit is only performed in the second frequency domain part of the target time unit.


Taking the first frequency domain part being used for downlink transmission as an example, the transmission direction of the first frequency domain part of the target time unit is downlink, the downlink transmission on the target time unit is performed in the first frequency domain part, and the uplink transmission on the target time unit is only performed in the second frequency domain part of the target time unit.

Then, the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the first frequency domain part is used for uplink transmission and the second frequency domain part is used for downlink transmission. In this case, the target time unit can be used for uplink transmission and downlink transmission, and the uplink transmission and downlink transmission do not overlap in the time domain.

In the determination mode A6, for the target time unit, as illustrated in FIG. 7F, when the target time unit is configured to include the first frequency domain part whose transmission direction is uplink by the first configuration information, the transmission direction of the target time unit is configured to be flexible by the second configuration information, the target time unit is scheduled for uplink transmission, and the first frequency domain resource is located within the first frequency domain part. Then, the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part.


In some embodiments, the transmission direction of the second frequency domain part is flexible. In a case that the first frequency domain part is used for uplink transmission and the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the downlink transmission is scheduled only in the second frequency domain part.


In the determination mode A7, the first frequency domain resource occupying the second frequency domain part of the target time unit may be understood to be that the first frequency domain resource occupies only the second frequency domain part and does not occupy the first frequency domain part.

Then, the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, and the second frequency domain part is used for downlink transmission. In this case, the target time unit can be used for uplink transmission and downlink transmission, and the uplink transmission and downlink transmission do not overlap in the time domain.


It may be understood that the determination modes A1 to A4 are used for determining the transmission mode of the target time unit in a case that the target time unit is not scheduled, and the determination modes A5 to A9 are used for determining the transmission mode of the target time unit in a case that the transmission direction of the target time unit is configured to be flexible and the target time unit is scheduled. The frequency domain relationship between the scheduled uplink resource and the first frequency domain part is not considered in the determination modes A5 and A9, and the frequency domain relationship between the scheduled uplink resource and the first frequency domain part is needed to be considered in the determination modes A6 to A8.

In the case that the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the transmission resource used for transmission in the first frequency domain part is determined based on the first uplink resource configuration information. In the case that the entire frequency domain of the target time unit as a whole is used for uplink transmission, the transmission resource used for transmission in the target time unit is determined based on the second uplink resource configuration information.

In the case that the transmission mode of the first frequency domain part is independent of the transmission mode of the second frequency domain part, the downlink resource in the first frequency domain part is determined based on the first downlink resource configuration information. In the case that the entire frequency domain of the target time unit as a whole is used for downlink transmission, the downlink resource in the target time unit is determined based on the second downlink resource configuration information.


In some embodiments, the target time unit is scheduled for uplink transmission in the determination modes A5 to A8 and B9.

If the target time unit is scheduled for the PUCCH transmission, the first frequency domain resource is a PUCCH frequency domain resource.


In some embodiments, the target time unit is scheduled for downlink transmission in the determination modes A9 and B5 to B8. The downlink transmission may include a Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission. If the target time unit is scheduled for the PDSCH transmission, the second frequency domain resource is a PDSCH frequency domain resource. If the target time unit is scheduled for the PDCCH transmission, the second frequency domain resource is a PDCCH frequency domain resource.

Optionally, if the first frequency domain part is used for downlink transmission, a transmission direction of a time unit in the first time domain resource is configured to be uplink by the second configuration information.


If the first frequency domain part is used for uplink transmission, it is limited that the transmission direction of the time unit in the first time domain resource is configured to be downlink by the second configuration information. In this case, the first frequency domain part of the target time unit is used for uplink transmission, and the second frequency domain part is used for downlink transmission. The limiting that the transmission direction of the time unit in the first time domain resource is configured to be downlink by the second configuration information may be understood to be that the transmission direction of the time unit in the first time domain resource is configured to be only downlink by the second configuration information.


If the first frequency domain part is used for downlink transmission, it is limited that the transmission direction of the time unit in the first time domain resource is configured to be uplink by the second configuration information. In this case, the first frequency domain part of the target time unit is used for downlink transmission, and the second frequency domain part is used for uplink transmission. The limiting that the transmission direction of the time unit in the first time domain resource is configured to be uplink by the second configuration information may be understood to be that the transmission direction of the time unit in the first time domain resource is configured to be only uplink by the second configuration information


In the embodiments of the present disclosure, the transmission direction of the time unit including the first frequency domain part configured by the second configuration information is limited based on the transmission direction of the first frequency domain part, thereby avoiding collision between the first configuration information and the second configuration information while realizing simultaneous uplink transmission and downlink transmission in one time unit.

In operation S801, a terminal device receives an uplink part time domain configuration and an uplink-downlink configuration.


The uplink part time domain configuration is the first configuration information of which the indicated frequency domain resource is a frequency domain position of an uplink part. The uplink part time domain configuration is used for indicating a slot/symbol occupied by an SBFD slot/symbol including an uplink part (i.e., an uplink subband), in one transmission period, and a frequency domain position occupied by the uplink part in the SBFD slot/symbol.


The uplink-downlink configuration is the second configuration information, and is used for indicating the transmission directions of respective slots/symbols in one transmission period. The uplink-downlink configuration may include one or more of a TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated.


In operation S802, the terminal device determines a type and/or a transmission mode of the slot/symbol based on the uplink part time domain configuration, or based on the uplink part time domain configuration and the uplink-downlink configuration.


Here, for a slot/symbol that is semi-statically configured to be flexible and is indicated to include an uplink part, the slot/symbol is a slot/symbol including an uplink part, or an uplink slot/symbol, or a slot/symbol determined to include an uplink part according to scheduling, or an uplink slot/symbol determined according to scheduling, a slot/symbol determined to include an uplink part according to an SFI indication, or an uplink slot/symbol determined according to an SFI indication. Each of slots/symbols is transmitted in a respective transmission mode.


Hereinafter, the wireless communication method provided by the embodiment of the present disclosure will be described with reference to different examples: first example and second example.


In the first example, the transmission mode is determined based on the uplink part time domain configuration.


In operation S11, the terminal receives the uplink part time domain configuration and the uplink-downlink configuration.


Here, the uplink part time domain configuration is used to indicate an uplink part and a slot/symbol including the uplink part (indicating SBFD).


The uplink part time domain configuration indicates a slot/symbol including the uplink part.


The uplink part time domain configuration indicates the slot/symbol including the uplink part by at least one of the following modes: first mode, second mode and third mode.


In the first mode, whether each slot/symbol in a period is a slot/symbol including the uplink part is indicated in a manner of bitmap.


For example, the value 1 indicates that the slot/symbol includes the uplink part, and the value 0 indicates that the slot/symbol does not include the uplink part.


As illustrated in FIG. 9, 10 bits [0 0 1 1 1 1 1 1 0 0] are adopted to indicate an uplink part time domain configuration of 10 slots included in one period of 10 ms. The [0 0 1 1 1 1 1 1 0 0] indicates that the third to eighth slots, i.e., slots 3 to 8, include the uplink part.


In the second mode, the number of slots/symbols including the uplink part in one period is indicated in a counting manner.


Further, the slot/symbol including the uplink part ends at the uplink slot/symbol. As illustrated in FIG. 9, when the number of slots including the uplink part is indicated to be 6, 6 slots are counted forward from the previous slot of the first uplink slot, i.e., the eighth slot, that is, the third to eighth slots include the uplink part.


In the third mode, the starting slot/symbol and the number of slots/symbols in one period are indicated in a manner of resource indication value (RIV).


In one example, when the RIV is 52, the starting slot is the third slot and the number of slots is 6, that is, the third to eight slots are slots including the uplink part.


The period is configured by the network device.


In some embodiments, the period of the uplink part time domain configuration coincides with the period of the uplink-downlink configuration. For example, if only pattern 1 is configured in the uplink-downlink configuration and pattern 1 is dl-UL-TransmissionPeriodicity P, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P. If pattern 1 and pattern 2 are configured in the uplink-downlink configuration, and pattern 1 is dl-UL-TransmissionPeriodicity P and pattern 2 is dl-UL-TransmissionPeriodicity P2, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P+dl-UL-TransmissionPeriodicity P2.


In operation S12, the terminal determines the type and/or the transmission mode of the slot/symbol based on the uplink part time domain configuration.


According to the configurations received in the operation S11, the terminal knows that the slots 3 to 8 include the uplink part. Regardless of whether the slots 3 to 8 are downlink slots, flexible slots, or even uplink slots (except for the counting method), as illustrated in FIG. 9, information is transmitted and received in the slots 3 to 8 according to the configuration including the uplink part.


For example, for the slot/symbol including the uplink part, the uplink transmission is limited to the uplink part. For another example, the downlink transmission can only be performed in frequency domains other than the uplink part. For another example, the network configures for the terminal two PUCCH configurations (PUCCH-Config): PUCCH-Config 1 and PUCCH-Config 2, where the PUCCH-Config 1 is used for the uplink part, and the PUCCH-Config 2 is used for the uplink slot/flexible slot. For slots 3 to 8, PUCCH resources are determined according to the PUCCH-Config 1, and for slots 9 to 10, PUCCH resources are determined according to the PUCCH-Config 2.


In the second example, the transmission mode is determined based on the uplink part time domain configuration and the uplink-downlink configuration.


In operation S21, the terminal receives the uplink part time domain configuration and the uplink-downlink configuration.


Here, the uplink part time domain configuration is used for indicating an uplink part and a slot/symbol including the uplink part (indicating SBFD).


The uplink part time domain configuration indicates a slot/symbol including the uplink part.


The uplink part time domain configuration indicates the slot/symbol including the uplink part by at least one of the following modes: first mode, second mode and third mode.


In the first mode, whether each slot/symbol in one period is a slot/symbol including the uplink part is indicated in a manner of bitmap.


For example, the value 1 indicates that the slot/symbol includes the uplink part, and the value 0 indicates that the slot/symbol does not include the uplink part.


As illustrated in FIG. 10, 10 bits [0 0 1 1 1 1 1 1 1 1 1] are adopted to indicate an uplink part time domain configuration of 10 slots included in one period of 10 ms. The [0 0 1 1 1 1 11 1 1 1 1 1] indicates that the third to tenth slots include the uplink part.


In the second mode, the number of slots/symbols including the uplink part in one period is indicated in a counting manner.


Further, the slot/symbol including the uplink part ends at the last slot/symbol. As illustrated in FIG. 10, when the number of slots including the uplink part is indicated to be 8, 8 slots are counted forward from the last slot, i.e., the tenth slot. That is, the slots 3 to 10 include the uplink part.


In the third mode, the starting slot/symbol and the number of slots/symbols in one period are indicated in a manner of RIV.


In one example, when the RIV is 72, the starting slot is the third slot and the number of slots is 8. That is, slots 3 to 10 include the uplink part.


The period is configured by the network device.


In some embodiments, the period of the uplink part time domain configuration coincides with the period of the uplink-downlink configuration. For example, if only pattern 1 is configured in the uplink-downlink configuration and pattern 1 is dl-UL-TransmissionPeriodicity P, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P. If pattern 1 and pattern 2 are configured in the uplink-downlink configuration and pattern 1 is dl-UL-TransmissionPeriodicity P and pattern 2 is dl-UL-TransmissionPeriodicity P2, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P+dl-UL-TransmissionPeriodicity P2.


The uplink-downlink configuration may be indicated by TDD-UL-DL-ConfigCommon, or by TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated.


As illustrated in FIG. 11, the uplink-downlink configuration is nrofDownlinkSlots=4, representing that four slots (slots 1 to 4) counted backward from the first slot are downlink slots; nrofDownlinkSymbols=0, representing that the downlink symbol is not included in the fifth slot, nrofUplinkSlots=2, representing that two slots (slots 9 and 10) counted forward from the last slot are uplink slots; nrofUplinkSymbols=0, representing that the uplink symbol is not included in the eighth slot. As illustrated in FIG. 11, slots 5 to 8 are flexible slots (F).


In operation S22, the terminal determines the type and/or the transmission mode of the slot/symbol based on the uplink part time domain configuration and the uplink-downlink configuration.


In the first scenario, if a slot/symbol is indicated to include an uplink part based on the uplink part time domain configuration and is also indicated to be a downlink slot/symbol based on the uplink-downlink configuration, the slot/symbol is a slot/symbol including the uplink part (or an SBFD slot/symbol).


For slots 3 and 4 illustrated in FIG. 10 to FIG. 12, slots 3 and 4 include the uplink part as illustrated in FIG. 10, slots 3 and 4 are indicated to be downlink slots as illustrated in FIG. 11, and slots 3 and 4 are slots including the uplink part as illustrated in FIG. 12.


In some embodiments, information transmission on the slot/symbol is processed according to a configuration corresponding to the SBFD slot/symbol.


For example, for the slot including the uplink part, the uplink transmission is limited to the uplink part. For another example, the downlink transmission can only be performed in frequency domains other than the uplink part. For another example, the network configures for the terminal two PUCCH-Configs: PUCCH-Config 1 and PUCCH-Config 2, where the PUCCH-Config 1 is used for the uplink part, and the PUCCH-Config 2 is used for the uplink slot. For slots 3 to 4, PUCCH resources are determined according to the PUCCH-Config 1.


In the second scenario, if a slot/symbol is indicated to include an uplink part based on the uplink part time domain configuration and is also indicated to be an uplink slot/symbol based on the uplink-downlink configuration, the slot/symbol is an uplink slot/symbol.


For slots 9 and 10 as illustrated in FIG. 10 to FIG. 12, the slots 9 and 10 include an uplink part as illustrated in FIG. 10, the slots 9 and 10 are indicated to be uplink slots as illustrated in FIG. 11, and the slots 9 and 10 are uplink slots as illustrated in FIG. 12.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the uplink slot/symbol. For example, the uplink transmission may be scheduled on the entire BWP bandwidth. For another example, the network configures for the terminal two PUCCH-Configs: PUCCH-Config 1 and PUCCH-Config 2, where PUCCH-Config 1 is used for the uplink part, and PUCCH-Config 2 is used for the uplink slot. For the slots 9 to 10, the PUCCH resource is determined according to the PUCCH-Config 2.


In the third scenario, if a slot/symbol is indicated to include an uplink part based on the uplink part time domain configuration and is also indicated to be a flexible slot/symbol based on the uplink-downlink configuration, the slot/symbol is one of the following cases A1, A2, A3.


In the case A1, the slot/symbol is an uplink slot/symbol.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the uplink slot/symbol. For example, the uplink transmission may be scheduled on the entire BWP bandwidth. For another example, the network configures for the terminal two PUCCH-Configs: PUCCH-Config 1 and PUCCH-Config2, where the PUCCH-Config 1 is used for the uplink part and the PUCCH-Config 2 is used for the uplink slot. For the slot, the PUCCH resource is determined according to the PUCCH-Config 2.


The use of uplink resources can be maximized in the case A1.


In the case A2, the slot/symbol is a slot/symbol including an uplink part (or SBFD slot/symbol).


The information transmission on the slot/symbol is processed according to the configuration corresponding to the SBFD slot/symbol. For example, for the slot/symbol including the uplink part, the uplink transmission is limited to the uplink part. For another example, the downlink transmission can only be performed in frequency domains other than the uplink part. For another example, the network configures for the terminal two PUCCH-Configs: PUCCH-Config 1 and PUCCH-Config2, where the PUCCH-Config 1 is used for the uplink part and the PUCCH-Config 2 is used for the uplink slot. For the slot, the PUCCH resource is determined according to the PUCCH-Config 1.


As illustrated in FIG. 10 to FIG. 12, slots 5 to 8 are indicated to include the uplink part and are also indicated to be flexible slots (F). Then, the slots 5 to 8 are slots including the uplink part.


In the case A2, the use of downlink resources can be maximized, and unnecessary interference caused by receiving information in the uplink part can be avoided.


In the case A3, the slot/symbol is determined to be an uplink slot/symbol or a slot/symbol including an uplink part according to a scheduling situation thereof.


In a method 3.1A, the slot/symbol is determined to be an uplink slot/symbol or a slot/symbol including an uplink part according to the scheduling situation thereof and a frequency domain relationship between the uplink resource and the uplink part.


In a method 3.1.1A, if the slot/symbol is scheduled for PDSCH, the slot/symbol is a slot/symbol including an uplink part, and downlink data is received only in an area other than the uplink part in the slot/symbol.


In a method 3.1.2A, if the slot/symbol is scheduled for PUSCH or PUCCH, and the PUSCH resource or PUCCH resource is allocated to the frequency domain resource other than the uplink part, the slot/symbol is an uplink slot/symbol, and the uplink transmission may be scheduled on the entire BWP bandwidth.


In a method 3.1.3A, if the slot/symbol is scheduled for PUSCH or PUCCH, and the PUSCH resource or PUCCH resource is allocated to the frequency domain resource only on the uplink part, the slot/symbol is a slot/symbol including the uplink part, and the uplink transmission is only scheduled on the uplink part.


It should be noted that the PUSCH resource and the PUCCH resource in the methods 3.1.2A and 3.1.3A are not distinguished between the configuration used for the uplink part and the configuration used for the uplink slot/symbol. There is only one PUSCH configuration or PUCCH configuration. The PUSCH resource or PUCCH resource is determined based on the PUSCH configuration or the PUCCH configuration. In a case that the symbol/slot is scheduled to PUSCH or PUCCH, it is determined whether the symbol/slot is an uplink slot/symbol or a slot/symbol including the uplink part based on the frequency domain relationship between the PUSCH resource or the PUCCH resource and the uplink part.


In a method 3.2A, the slot/symbol is determined to be an uplink symbol or a symbol including an uplink part according to a scheduling situation.


In a method 3.2.1A, if the slot/symbol is scheduled for PDSCH, the slot/symbol is a slot/symbol including an uplink part, and downlink data is received only in an area other than the uplink part of the slot/symbol.


In a method 3.2.2A, if the slot/symbol is scheduled for PUSCH or PUCCH, the slot/symbol is an uplink slot/symbol.


The uplink transmissions may be scheduled on the entire BWP bandwidth.


For another example, the network configures for the terminal two PUCCH-Configs, where the PUCCH-Config 1 is used for the uplink part, and the PUCCH-Config 2 is used for the uplink slot. For the slot/symbol, the PUCCH resource is determined according to the PUCCH-Config 2.


In the third example, the transmission mode is determined based on the uplink part time domain configuration and the dynamic uplink-downlink configuration


In operation S31, the terminal receives the uplink part time domain configuration and the uplink-downlink configuration.


The uplink part time domain configuration is used to indicate a frequency domain resource and a time domain resource in which the frequency domain resource is located. The frequency domain resource enables the time domain resource to be used for uplink transmission and downlink transmission. The frequency domain resource can allow that uplink transmission and downlink transmission of the time domain resource do not overlap in the time domain.


Here, the uplink part time domain configuration is used to indicate the uplink part and a slot or symbol including the uplink part (indicating SBFD).


The uplink part time domain configuration indicates a slot/symbol including the uplink part.


The uplink part time domain configuration indicates the slot/symbol including the uplink part by at least one of the following modes: first mode, second mode, third mode.


In the first mode, whether each slot/symbol in one period is a slot/symbol including the uplink part is indicated in a manner of bitmap.


For example, the value 1 indicates that the slot/symbol includes the uplink part, and the value 0 indicates that the slot/symbol does not include the uplink part.


As illustrated in FIG. 10, 10 bits [0 0 1 1 1 1 1 1 1 1 1] are adopted to indicate an uplink part time domain configuration of 10 slots included in one period of 10 ms. The [0 0 1 1 1 1 1 1 1 1 1 1 1] indicates that the third to tenth slots include the uplink part.


In the second mode, the number of slots/symbols including the uplink part in one period is indicated in a counting manner.


Further, the slot/symbol including the uplink part ends at the last slot/symbol. As illustrated in FIG. 10, when the number of slots including the uplink part is indicated to be 8, 8 slots are counted forward from the last slot, i.e., the tenth slot. That is, the slots 3 to 10 include the uplink part.


In the third mode, the starting slot/symbol and the number of slots/symbols in one period are indicated in a manner of RIV.


In one example, when the RIV is 72, the starting slot is the third slot and the number of slots is 8, that is, slots 3 to 10.


The period is configured by the network device.


In some embodiments, the period of the uplink part time domain configuration coincides with the period of the uplink-downlink configuration. For example, if only pattern 1 is configured in the uplink-downlink configuration and pattern 1 is dl-UL-TransmissionPeriodicity P, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P. If pattern 1 and pattern 2 are configured in the uplink-downlink configuration, and pattern 1 is dl-UL-TransmissionPeriodicity P and pattern 2 is dl-UL-TransmissionPeriodicity P2, the period of the uplink part time domain configuration is dl-UL-TransmissionPeriodicity P+dl-UL-TransmissionPeriodicity P2.


The uplink-downlink configuration may be indicated by TDD-UL-DL-ConfigCommon, or by TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated. As illustrated in FIG. 11, the uplink-downlink configuration is nrofDownlinkSlots=4, representing that four slots (slots 1 to 4) counted backward from the first slot are downlink slots;


nrofDownlinkSymbols=0, representing that the downlink symbol is not included in the fifth slot, nrofUplinkSlots=2, representing that two slots (slots 9 and 10) counted forward from the last slot are uplink slots; nrofUplinkSymbols=0, representing that the uplink symbol is not included in the eighth slot. As illustrated in FIG. 11, slots 5 to 8 are flexible slots (F).


Further, the flexible slot/symbol is set through the SFI received by the terminal device, and is indicated to be an uplink slot/symbol or a downlink slot/symbol.


In one example, according to SFI, the fifth slot in the period illustrated in FIG. 11 is indicated to be the downlink slot (D), and the eighth slot is indicated to be the uplink slot (U). Then, the indication result is as illustrated in FIG. 13, where the first to fifth slots are downlink slots, the sixth to seventh slots are flexible slots, and the eighth to tenth slots are uplink slots.


In operation S32, the terminal determines a type and/or a transmission mode of a slot/symbol based on the uplink part time domain configuration.


For the transmission modes of the first to fourth, sixth to seventh, and ninth to tenth slots in FIG. 13, the reference may be made to the method for determining the transmission mode of the slot/symbol in the second example.


When a slot/symbol is semi-statically configured to be flexible and is indicated to include an uplink part based on the uplink part time domain configuration, and it is dynamically indicated to be a downlink slot/symbol, the slot/symbol is a slot/symbol including an uplink part (or SBFD slot/symbol).


As illustrated in FIG. 10, FIG. 13, and FIG. 14, the slot 5 includes an uplink part in FIG. 10, the slot 5 is indicated through the SFI to be a downlink slot in FIG. 13, and the slot 5 is a slot including an uplink part in FIG. 14.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the SBFD symbol. For example, for a slot including an uplink part, the uplink transmission is limited to the uplink part. For another example, the downlink transmission can only be performed in frequency domains other than the uplink part. For another example, the network configures two PUCCH-Configs for the terminal, where the PUCCH-Config 1 is used for the uplink part, and the PUCCH-Config 2 is used for the uplink slot. For the slot, the PUCCH resource is determined according to the PUCCH-Config 1.


Based on the above solution, the use of downlink resources can be maximized, and an unnecessary interference caused by receiving information in the uplink part can be avoided.


When a slot/symbol is semi-statically configured to be flexible and is indicated to include an uplink part based on the uplink part time domain configuration, and it is dynamically indicated to be an uplink slot/symbol, the slot/symbol is an uplink slot/symbol.


As illustrated in FIG. 10, FIG. 13, and FIG. 14, the slot 8 includes an uplink part in FIG. 10, the slot 8 is indicated through the SFI to be an uplink slot in FIG. 13, and the slot 8 is an uplink slot in FIG. 14.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the uplink slot/symbol. For example, the uplink transmission may be scheduled on the entire BWP bandwidth. For another example, the network configures two PUCCH-Configs for the terminal, where the PUCCH-Config 1 is used for the uplink part, and the PUCCH-Config 2 is used for the uplink slot. For the slot, the PUCCH resource is determined according to the PUCCH-Config 2. In this way, the use of uplink resources is maximized.


In the above example, the wireless communication method of the present disclosure is described taking the uplink part as an example. In the embodiments of the present disclosure, the first configuration information may be used to indicate a slot/symbol including a downlink part (downlink sub-band). In this case, the first configuration information may be a downlink part time domain configuration.


The downlink part time domain configuration is used for indicating the downlink part and a slot/symbol including the downlink part (indicating SBFD).


For the indication mode in which the downlink part time domain configuration indicates the slot/symbol including the downlink part, the reference may be made to the indication mode in which the uplink part time domain configuration indicates the slot/symbol including the uplink part.


In a case that the terminal device receives the downlink part time domain configuration and the uplink-downlink configuration, and a slot/symbol is indicated by the downlink part time domain configuration to include the downlink part and is indicated by the uplink-downlink configuration, the terminal device determines a type or transmission mode of the slot/symbol based on the downlink part time domain configuration, or based on the downlink part time domain configuration and the uplink-downlink configuration.


In a case that the terminal device determines the type or the transmission mode based on the downlink part time domain configuration, the slot/symbol includes the downlink part. For a slot/symbol including the downlink part, the downlink transmission is limited to the downlink part. For another example, the uplink transmission can only be performed in frequency domains other than the downlink part. For another example, the network configures for the terminal two PDCCH configurations (PDCCH-Config): PDCCH-Config 1 and PDCCH-Config 2, where the PDCCH-Config 1 is used for the downlink part, and the PDCCH-Config 2 is used for the downlink slot/flexible slot. For the slot/symbol including the downlink part, the PDCCH resource is determined by using the PDCCH-Config 1. For the downlink slot/symbol, the PDCCH resource is determined by using the PDCCH-Config 2.


In a case that the terminal device determines the type or transmission mode of the slot/symbol based on the downlink part time domain configuration and the uplink-downlink configuration, the slot/symbol is one of the following cases: B1, B2, B3.


In the case B1, the slot/symbol is a downlink slot/symbol.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the downlink slot/symbol. For example, the downlink transmission may be scheduled on the entire BWP bandwidth.


In the case B2, the slot/symbol is a slot/symbol including a downlink part.


The information transmission on the slot/symbol is processed according to the configuration corresponding to the slot/symbol including the downlink part. For example, for the slot/symbol including a downlink part, the downlink transmission is limited to the downlink part. For another example, the uplink transmission can only be performed in frequency domains other than the downlink part.


In the case B3, the slot/symbol is determined to be a downlink slot/symbol or a slot/symbol including a downlink part according to a scheduling situation.


In a method 3.1B, the slot/symbol is determined to be a downlink slot/symbol or a slot/symbol including a downlink part according to the scheduling situation and a frequency domain relationship between the downlink resource and the downlink part.


In a method 3.1.1B, if the slot/symbol is scheduled for PUSCH, then the slot/symbol is a slot/symbol including a downlink part, and uplink data is received only in an area other than the downlink part in the slot/symbol.


In a method 3.1.2B, if the slot/symbol is scheduled for PDSCH or PDCCH, and the PDSCH resource or PDCCH resource is allocated to the frequency domain resource other than the downlink part, then the slot/symbol is a downlink slot/symbol, and the downlink transmission may be scheduled on the entire BWP bandwidth.


In a method 3.1.3B, if the slot/symbol is scheduled for PDSCH or PDCCH, and the PDSCH resource or PDCCH resource is allocated to the frequency domain resource only on the downlink part, then the slot/symbol is a slot/symbol including the downlink part, and the downlink transmission is only on the downlink part.


In a method 3.2B, the slot/symbol is determined to be a downlink symbol or a symbol including a downlink part according to a scheduling situation.


In a method 3.2.1B, if the slot/symbol is scheduled for PUSCH, then the slot/symbol is a slot/symbol including a downlink part, and uplink data is received only in an area other than the downlink part of the slot/symbol.


In a method 3.2.2B, if the slot/symbol is scheduled for the PDSCH or PDCCH, the slot/symbol is a downlink slot/symbol.


The downlink transmissions may be scheduled on the entire BWP bandwidth.


In a case that a slot/symbol is indicated to include the downlink part and is indicated to be a flexible slot/symbol, and it is dynamically indicated to be an uplink slot/symbol through the SFI, the slot/symbol is a slot/symbol including a downlink part.


In a case that a slot/symbol is indicated to include the downlink part and is indicated to be a flexible slot/symbol, and it is dynamically indicated to be a downlink slot/symbol through the SFI, the slot/symbol is a slot/symbol including a downlink part.

FIG. 15 is a schematic diagram of an optional structural composition of a wireless communication apparatus according to an embodiment of the present disclosure. The wireless communication apparatus is applied to a terminal device. As illustrated in FIG. 15, the wireless communication apparatus 1500 includes a first communication unit 1501.


The first communication unit 1501 is configured to receive first configuration information transmitted by a network device. The first configuration information is used to indicate a first time domain resource. The first time domain resource includes one or more time units, each time unit including a first frequency domain part in frequency domain. Herein, for any one time unit included in the first time domain resource, a transmission direction of the first frequency domain part is different from a transmission direction of the time unit configured by second configuration information. The second configuration information is used to configure a transmission direction for each time unit in one period.


In the embodiment of the present disclosure, the wireless communication apparatus 1500 may further include a storage unit. The storage unit is configured to store the second configuration information.


In some embodiments, the first configuration information is used to indicate at least one of:

    • whether each time unit within a first period belonging to the first time domain resource;
    • a first number, the first time domain resource including the first number of time units in the first period; or
    • a first position and the first number, the first time domain resource including the first number of time units in the first period with the first position as a starting position or an ending position.


In some embodiments, the first period is determined based on the second configuration information.


In some embodiments, a transmission mode of a target time unit belonging to the first time domain resource includes one of:

    • entire frequency domain resource of the target time unit being used for uplink transmission as a whole;
    • entire frequency domain resource of the target time unit being used for downlink transmission as a whole; and
    • a transmission mode of a first frequency domain part of the target time unit being independent of a transmission mode of a second frequency domain part of the target time unit, the second frequency domain part being a frequency domain part of the target time unit other than the first frequency domain part.


In some embodiments, the transmission mode of the target time unit is determined based on the first configuration information.


In some embodiments, the transmission mode of the first frequency domain part of the target time unit is independent of the transmission mode of the second frequency domain part.


In some embodiments, the transmission mode of the target time unit is determined based on the first configuration information and the second configuration information.


In some embodiments, the transmission mode of the target time unit is determined by at least one of following modes:
