Patent Application
20230217322
This application pertains to the field of communications technologies, and specifically relates to a transmission processing method and apparatus and a terminal.
A long term evolution (LTE) system supports sidelink (SL) transmission, that is, data transmission between terminals (User Equipment, UE) is directly performed on a physical layer. LTE sidelink communication is based on broadcast. Although LTE sidelink can be used to support basic security communication of vehicle to everything (V2X), LTE sidelink is not applicable to other more advanced V2X services. A 5th generation (5G) new radio (NR) system supports more advanced sidelink transmission designs, such as unicast, multicast, or groupcast, and therefore can support more comprehensive service types. In addition, to enable an SL to carry acknowledgement/negative acknowledgement (ACK/NACK) feedback information, NR V2X supports a new SL channel, that is, a PSFCH (Physical Sidelink Feedback Channel). A period of the PSFCH channel in time domain is N (N = 0/1/2/4), where N can be understood as that every N (logical) slots include a PSFCH. N = 0 indicates that no PSFCH is configured in a resource pool.
However, in the prior art, communication between a vehicle and UE having low processing capability, especially pedestrian user equipment (Pedestrian UE, PUE) cannot support simultaneous processing of Uu TX/RX (that is, downlink (DL) receiving and uplink (UL) sending) and TX/RX information (for example, PSFCH information or data information) on the SL, resulting that different information processing requirements cannot be met and the efficiency is reduced.

Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.
The terms “first”, “second”, and the like in this specification and claims of this application are used to distinguish between similar objects rather than to describe a specific order or sequence. It should be understood that data used in this way is used interchangeably in appropriate circumstances so that the embodiments of this application can be implemented in other orders than the order illustrated or described herein. In addition, in this specification and claims, “and/or” represents at least one of connected objects, and the symbol “/” generally represents an “or” relationship between the associated objects.
It should be noted that the technologies described in the embodiments of this application are not limited to long term evolution (LTE)/LTE-Advanced (LTE-A) systems, and may also be used in various wireless communication systems such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency-division multiple access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are often used interchangeably. The technology described herein may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. However, in the following descriptions, a new radio (NR) system is described for an illustration purpose, and NR terms are used in most of the following descriptions, although these technologies may also be applied to other applications than an NR system application, for example, 6th (6th Generation, 6G) communication systems.
The following specifically describes the transmission processing method provided in the embodiments of this application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in
Step 201. Obtain configuration information of a gap.
In this step, the configuration information is used to determine a position of the gap, and the terminal can perform subsequent processing based on the position of the gap by obtaining the configuration information of the gap.
Step 202. Perform, based on the configuration information, at least one of the following within the gap:
Herein, the first radio technology and the second radio technology may correspond to different links. For example, the first radio technology corresponds to an SL, and the second radio technology corresponds to a DL or a UL. The first radio technology and the second radio technology may correspond to different air interfaces. For example, the first radio technology corresponds to a Uu interface, and the second radio technology corresponds to a PC5 interface. The first radio technology and the second radio technology may correspond to SLs of different radio access technologies (RAT). For example, the first radio technology corresponds to an LTE SL, so that the second radio technology corresponds to an NR SL. The first radio technology and the second radio technology may correspond to different SL channels. The SL channels include a physical sidelink broadcast channel (PSBCH), a PSFCH, a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The first radio technology and the second radio technology specifically correspond to two of such SL channels. The first radio technology and the second radio technology may correspond to different carriers. For example, the first radio technology corresponds to a carrier 1 which carries an NR DL or UL, and the second radio technology corresponds to a carrier 2 which carries an NR SL. The first radio technology and the second radio technology may alternatively correspond to different BWPs. Certainly, the first radio technology and the second radio technology are not limited to the foregoing implementations, which are not listed one by one herein.
In addition, the measurement on the information of the target radio technology herein also includes measurement on channels or reference signals in or the target radio technology.
Therefore, transmission based on the target radio technology may be transmission of one of the foregoing first radio technology and second radio technology.
The measurement on the information of the target radio technology may alternatively be measurement on information of one of the foregoing first radio technology and second radio technology. Specifically, SL information is measured within the gap; or in transmission of the SL information, if Uu interface information needs to be measured, the Uu interface information is measured within the gap. In this case, it is not required to receive the SL information within the gap.
The switching between the first radio technology and the second radio technology may be switching between air interfaces, for example, switching between the Uu interface and the PC5 interface, which may further specifically be switching between SL information sending or receiving and DL receiving or switching between SL information sending or receiving and UL sending; or may be switching between RATs, for example, switching between NR and LTE, which may further specifically be switching from an LTE SL to an NR SL or switching from an NR SL to an LTE SL; or may be switching between SL channels, for example, switching between two of the channels, which may further specifically be switching from a PSSCH to a PSFCH or switching from a PSFCH to a PSSCH or a PSCCH; or may be switching between frequencies, switching between bandwidth parts (BWP), or the like. The Uu interface is used for DL and/or UL transmission, and the PC5 interface is used for SL transmission.
In this way, in this step, after step 201, the terminal can perform, based on the configuration information, at least one of transmission based on the target radio technology, measurement on the information of the target radio technology, and switching between the first radio technology and the second radio technology within the gap.
In this way, in the method provided in this embodiment of this application, according to the foregoing step 201 and step 202, after the configuration information of the gap is obtained, at least one of transmission based on the target radio technology, measurement on the information of the target radio technology, and switching between the first radio technology and the second radio technology can be performed within the gap based on the configuration information, where the target radio technology is one of the first radio technology and the second radio technology. This can meet different information processing requirements, improve transmission efficiency, and implement interoperation between different air interfaces/RATs.
It can be learned from the foregoing content that the gap (GAP) in this embodiment may be configured on the Uu interface (or the UL and/or the DL) and used for receiving and/or sending the SL information, where certainly, it is not required to process the Uu interface information within the GAP; or may be configured on the SL and used for processing the Uu interface information, where certainly, it is not required to receive and/or send the SL information within the GAP; or may be configured on RAT 1 and used for processing of information of RAT 2, where certainly, it is not required to process information of the RAT 1 within the GAP; or may be configured on the RAT 2 and used for processing the information of the RAT 1, where it is not required to process the information of the RAT 1 within the GAP. The RAT 1 and RAT 2 are the same or different RATs.
For sending and/or receiving of first information, optionally, UE performs transmission through the Uu interface, and the UE can receive and/or send the SL information within the GAP, for example, PUE sends or receives PSFCH information, VUE sends or receives PSFCH, or PUE sends or receives the SL information; or UE performs transmission through an air interface 1, and the UE can receive and/or send data on an air interface 2 within the GAP. For measurement on second information, optionally, the measurement may be measurement on information or channels on PC5 or measurement on information or channels on Uu. In addition, in a case that UE is in the RAT 1, the UE can process the information of the RAT 2 within the GAP. Such processing includes at least one of sending, receiving, and measurement. Certainly, in a case that the information or channels on PC5 are measured within the GAP, it is not required to measure the information or channels on Uu within the GAP. Configuration of another GAP may be similar. Details are not described herein again.
For example, in a scenario in which PUE receives DL information, the PUE uses the method provided in this embodiment of this application. PUE 1 can receive, after obtaining configuration information of a gap, SL information within a gap for receiving DL information. Certainly, PUE 2 can also measure, after obtaining configuration information of the gap, the SL information in the gap for receiving DL information.
Optionally, the gap includes at least one of the following:
Transmission may be understood as sending, or receiving, or sending and receiving. Therefore, the duration for switching between downlink transmission and sidelink transmission may be a duration for switching between DL receiving and SL sending and/or receiving. A duration T for switching between DL receiving and SL sending and/or receiving may be a gap duration T1 for switching from DL receiving to SL sending or receiving, or may be a gap duration T2 for switching from SL sending or receiving to DL receiving. T1 and T2 may be the same or different. Likewise, this is also the case for the foregoing other switching durations, power adjustment durations, and gap durations for switching. Details are not listed one by one herein. In addition, in a case that a gap (GAP) includes a plurality of durations in the foregoing durations, the gap may be a sum of the plurality of durations or the maximum value in the plurality of durations.
Optionally, in this embodiment, the configuration information is used to configure at least one of the following:
In the configuration information, the period of the GAP is not necessarily enabled. In this embodiment, enabling may also be understood as activation, start, or indication.
Optionally, the configuration information is obtained by using at least one of the following manners:
Therefore, at least one of the length, start position, end position, offset position, timing advance information, period, and configuration quantity of the gap may be obtained by using at least one of manners including pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication. Certainly, pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication may directly describe configuration information of a GAP, for example, a length of the GAP is M symbols, and a start position is slot 0; or may give association description on the configuration information of the GAP, for example, DCI indicates an offset position of the start position of the GAP with respect to DCI receiving, where a value of the offset position may be positive or negative, which is not limited herein.
Optionally, the length of the gap is associated with a subcarrier spacing (SCS) and/or capability of the terminal.
For example, a larger SCS leads to a greater length of the GAP. For configuration of the length of the GAP, lengths of the GAP under different SCSs may also be defined through at least one of pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication. For example, the lengths of the GAP under different SCSs are configured through RRC, and UE determines a length of the GAP with reference to a current SCS.
The length of the GAP may be associated with the capability of the terminal. The capability of the terminal may be capability of supporting SCS lengths by the terminal, capability of supporting frequency bands by the terminal, or the like. An SCS processing manner may be defined based on the foregoing manner. In a case that the terminal supports only FR1 (frequency range 1), a set of configuration information is used. In a case that the terminal supports FR2, another set of configuration information is used under the FR2. Corresponding configuration information is selected based on capability. A gap configured under the FR2 is shorter.
Optionally, the start position of the gap is associated with a position of a physical sidelink feedback channel PSFCH.
For example, the start position of the GAP is the same as the position of the PSFCH or is obtained by adding a position of an offset value to the position of the PSFCH. The offset value may be positive or negative, which is not limited herein. Certainly, the start position of the GAP in the configuration information is not necessarily a start position for enabling the GAP. The position of the offset value may be an offset position of the gap in the configuration information. Certainly, the offset value may alternatively be obtained by using at least one of manners including pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication.
Optionally, the end position of the gap is associated with a position of a PSFCH.
Like the start position of the GAP, the end position of the GAP is the same as the position of the PSFCH or is obtained by adding a position of an offset value to the position of the PSFCH. The offset value may be positive or negative, which is not limited herein. The position of the offset value may be an offset position of the gap in the configuration information. Certainly, the offset value may alternatively be obtained by using at least one of manners including pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication.
Optionally, the period of the gap is associated with a period of a PSFCH.
For example, the period of the GAP is equal to the period of the PSFCH or uses the period of the PSFCH as a reference. Herein, the period of the GAP refers to a time interval at which the GAP periodically appears in a Uu BWP or an SL resource pool. In different periods, values of lengths of the GAP may be the same or different. Certainly, the period of the GAP in the configuration information is not necessarily a period for enabling the GAP.
In this embodiment, optionally, the configuration information corresponds to at least one of the following information:
Herein, the priority may be a channel priority, a data packet priority, a logical channel priority, a physical layer priority, or a priority indicated by a higher layer.
In this way, the configuration information of the GAP may correspond to one of the transmission type, the resource pool, the terminal, the terminal group, and the priority. Certainly, a correspondence may be one-to-one, one-to-many, many-to-one, or many-to-many. For example, configuration information of the GAP is configured for unicast and groupcast, where unicast corresponds to configuration information 1, and groupcast corresponds to configuration information 2; or configuration information of the GAP is configured for different groupcast types, where a groupcast type 1 corresponds to configuration information 3, and a groupcast type 2 corresponds to configuration information 4.
Optionally, the configuration information is periodically sent or is triggered based on a first preset event.
In this way, UE can periodically report the configuration information to a network-side device or a control node, periodically receive the configuration information sent by the network-side device or the control node, or obtain the configuration information in a case that the first preset event occurs. The first preset event may be: in a case that the terminal performs Uu interface data transmission, there is data to be transmitted on the PC5 interface; in a case that the terminal performs PC5 interface data transmission, there is data to be transmitted on the Uu interface; there is downlink data to be transmitted on a network-side device or a control node; and a network-side device or a control node has configured a periodic uplink resource for the terminal, and there is uplink data transmission on the terminal. Certainly, the first preset event is not limited to the foregoing content. Details are not listed one by one herein.
In this way, in a case that when UE is sending or receiving Uu interface data (that is, receiving DL data and sending UL data), there is SL information to be sent or received, the UE can request for configuration of the GAP from the network-side device or the control node, or the UE can report the configuration information of the GAP to the network-side device or the control node. After the configuration information has been reported to the network-side device or the control node, the network-side device or the control node does not schedule UL or DL data within the GAP, and the UE sends information on the SL, thereby avoiding collision.
In a case that there is DL data transmission on the network-side device or the control node, the configuration information of the GAP is configured for the UE.
In a case that a periodic UL resource has been configured for the UE by the network-side device or the control node, when there is UL information transmission on the UE, the configuration information of the GAP is sent on the periodic UL resource configured. In this case, the configuration information of the GAP is configured by the network-side device. The periodic UL resource is small and is only used for sending the configuration information of the GAP. However, if there is UL data to be sent, the UE dynamically triggers enabling of the GAP. The network-side device receives the configuration information of the GAP, and receives the UL information of the UE within a corresponding GAP. In V2X, sharing may be implemented for a UL and an SL.
A period of the configuration information may be the same as or different from a period of the GAP. In addition, a periodic resource of the configuration information may be independently configured or associated with configuration of the GAP.
Optionally, the gap is enabled by using at least one of the following manners:
In this embodiment, enabling of the GAP means: within the GAP, sending and/or receiving first information, performing measurement on transmission of second information, and/or performing switching. For example, when UE is receiving data on a DL BWP or a UL BWP, if the GAP is enabled, the UE receives or sends data on an SL; when the UE is receiving or sending data on an SL, if the GAP is enabled, the UE receives data on a DL or sends data on a UL.
Herein, being enabled based on triggering of a second preset event means that in a case that the second preset event occurs, the GAP may be directly triggered, that is, the GAP is enabled.
In a case of being enabled based on a period, the period may be a period in configuration information; or in a case that the first preset event occurs, may be an enabling period T′ corresponding to the first preset event and obtained by using at least one of manners including pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication. The GAP is enabled according to the enabling period T′. For example, a GAP is present every T′ time intervals in a Uu BWP or an SL resource pool, and is used for receiving or sending data on Uu or SL. The enabling period may be the same as or different from a configuration period.
Being enabled based on indication of first preset signaling means that the GAP is enabled after the first preset signaling has been received. The indication of the first preset signaling may be explicit indication or implicit indication. For example, SCI indication is hybrid automatic repeat request (HARQ) enable. The SCI may be used as the first preset signaling for indicating enabling. Certainly, in a case that PSFCH receiving is performed within the GAP, an existing field in the SCI may also be used for GAP enabling indication, so as to reduce signaling overheads. Certainly, the first preset signaling may alternatively be triggered by a specific event, for example, a second preset event.
Optionally, the second preset event includes at least one of the following:
Certainly, the second preset event includes but is not limited to the foregoing content. Details are not listed one by one herein.
Optionally, in a case of enabling the gap based on indication of the first preset signaling, the gap is enabled in a first duration after the first preset signaling is sent or received.
In a case that the first preset signaling is dynamic signaling, the first duration is a demodulation duration of the first preset signaling; or in a case that the first preset signaling is RRC signaling, the first duration is a corresponding duration in which a first timer meets a specific condition or expires. The specific condition may be a sending end of the RRC signaling having received acknowledgement (ACK) information from a receiving end, or other conditions configured or defined. Details are not listed one by one herein.
In this way, in a case of enabling the GAP based on indication of the first preset signaling, where the first preset signaling is dynamic signaling, the GAP is enabled after demodulation of the first preset signaling, meaning that a start position for enabling the GAP is at least on a next position corresponding to the receiving moment of the first preset signaling plus the first duration. For example, a GAP may be configured by RRC configuration at slot 0, slot 5, slot 10, and slot 15. If DCI indicates enabling a GAP at slot 8, and a DCI processing time (that is, the first duration) is 2 slots, meaning that DCI information can be demodulated or enabling signaling can be obtained in 2 slots, a GAP in slot 10 is enabled. If DCI indicates enabling a GAP in slot 9, and a DCI processing time is 2 slots, meaning that enabling signaling carried on the DCI can be demodulated at slot 10, a next GAP (that is, the gap in slot 15) is the first GAP enabled.
In addition, in this embodiment, an enabling quantity of the gap is N, where positions of N gaps are continuous or discontinuous.
Herein, the enabling quantity of the GAP may be obtained by using at least one of manners including pre-definition, pre-configuration, RRC configuration, MAC CE configuration, DCI indication, and SCI indication. Based on the enabling quantity N of the GAP, after the first GAP enabled, N-1 continuous or discontinuous GAPs can be enabled. Certainly, in a case that the enabling quantity N of the GAP is present, after a quantity of GAPs enabled is greater than N, the GAP is disabled.
The N gaps are N continuous gaps in gaps configured and are not required to be continuous in time domain. For example, a duration of each gap is 1 subframe (that is, 1 ms). In a case that subframe 5 (SF5), SF15, SF25, SF35, SF45, SF55, SF65, and SF75 are possible positions for configuration, if one piece of enabling signaling (first preset signaling) is received in subframe 24 and the enabling quantity configured is 3, SF25, SF35, and SF45 are positions for enabling a GAP, and UE perform related operations in these GAPs.
Optionally, the gap is disabled through indication of second preset signaling.
In other words, GAP disabling is indicated through the second preset signaling. The second preset signaling may be explicit indication or implicit indication. Details are not described herein. The first preset signaling and the second preset signaling may be the same or different.
Optionally, the first preset signaling includes at least one of the following:
Optionally, the second preset signaling includes at least one of the following:
In this embodiment, on one hand, enabling can be performed based on configuration information, that is, after configuration information of a GAP is obtained, the GAP is enabled based on the configuration information. For example, configuration information of a GAP is configured by RRC, and after a terminal obtains the configuration information of the GAP through RRC, the GAP is enabled based on the configuration information. On the other hand, a GAP is configured semi-persistently. On the basis of configuration information, the GAP is enabled based on triggering of the second preset event or the first preset signaling, reducing physical layer signaling overheads and improving efficiency and coverage. For example, configuration information of a GAP is configured by RRC; after a terminal obtains the configuration information of the GAP through RRC, DCI or SCI for indicating enabling is further received; and after enabling signaling is obtained through demodulation of the DCI or SCI, the GAP is enabled.
In this embodiment, it should be further known that units of parameters such as a length, a start position, an end position, an offset position, and a timing advance position corresponding to timing advance information of a GAP may be millisecond, second, slot, mini-slot, multi-slot, frame, subframe, or the like. In addition, the units of the parameters may be the same or different.
The following describes the application of the method provided in this embodiment of this application with reference to specific scenarios.
Scenario 1: For PUE, a length of an SL reception gap GAP (for example, the length is K slots) is pre-configured for the PUE through RRC. DCI is used for enabling the GAP. A start position for enabling the GAP is obtained according to a position of the DCI and an offset value indicated by the DCI.
The start position for enabling the GAP is obtained by adding a slot offset value indicated by the DCI to the position of the DCI. PUE performs at least one of switching from a DL to an SL, receiving of PSFCH information, and switching from an SL to a DL within the GAP.
Scenario 2: A pre-configured enabling period of a GAP is associated with a period of a PSFCH. In a case that a period of a PSFCH configured in a resource pool for PUE is configured to be a non-zero value, an enabling period of a GAP of the PUE is the period of the PSFCH. In a case that a period of a PSFCH configured in a resource pool for PUE is zero, no GAP is configured.
When PUE is receiving information on a receiving DL BWP, if SCI indication for scheduling data transmission on an SL is feedback-based data transmission, the PUE enables a GAP in a corresponding position, receives PSFCH information within the GAP, and reports related parameters (such as a length and a start position for enabling) of the GAP enabled to a base station. The base station sends no DL data to the PUE within the GAP.
Scenario 3: Configuration information of a GAP is configured through RRC under NR SL and the GAP is enabled based on the configuration information. In this case, UE can process information on an LTE SL within the GAP.
Certainly, in this embodiment, specific implementation is described by using transmission on an SL and a UL or a DL for example. However, a GAP can also be used for transmission on a backhaul link and a fronthaul link.
To sum up, according to the method provided in this embodiment of this application, after the configuration information of the gap is obtained, at least one of transmission based on the target radio technology, measurement on the information of the target radio technology, and switching between the first radio technology and the second radio technology can be performed within the gap based on the configuration information, where the target radio technology is one of the first radio technology and the second radio technology. This can meet different information processing requirements, improve transmission efficiency, and implement interoperation between different air interfaces/RATs.
It should be noted that the transmission processing method provided in this embodiment of this application may be performed by a transmission processing apparatus or a control module for performing or loading the transmission processing method in the transmission processing apparatus.

This can meet different information processing requirements, improve transmission efficiency, and implement interoperation between different air interfaces/RATs.
