Embodiments of the present application relate to the field of communications and, in particular, to a method for transmitting information and receiving information and a communication device.
Unlicensed spectrum is a spectrum that can be used for radio device communication divided by countries and regions. The spectrum is generally considered to be a shared spectrum, that is, communication devices in different communication systems can use the spectrum as long as they meet regulatory requirements set by the countries or the regions on the spectrum, and there is no need to apply for a proprietary spectrum authorization from governments. For example, in some areas, the communication device follows a principle of “Listen Before Talk”, that is, the communication device needs to perform channel detection before transmitting a signal on a channel of the unlicensed spectrum. Only when the channel detection result is that the channel is idle, the communication device performs signal transmission. If the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot perform signal transmission. With the development of wireless communication technology, both the long term evolution (LTE) system and the new radio (NR) system will consider deploying networks on unlicensed spectrum to use unlicensed spectrum for perform data service transmission.
In the NR system where the networks are deployed on the unlicensed spectrum (New Radio-based access to unlicensed spectrum, NR-U), since the terminal device may need to detect the channel on the unlicensed spectrum through channel detection before sending the physical uplink control channel (Physical Uplink Control Channel, PUCCH). The PUCCH can be sent when the channel is idle, otherwise it cannot be sent. When the control information transmitted in the PUCCH channel is hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request ACK, HARQ-ACK), if the PUCCH cannot be sent due to a failure of the channel detection, it will have a greater impact on delay/performance of an entire link.
Therefore, in the NR-U system, it is necessary to increase a transmission opportunity of the HARQ-ACK to ensure the delay and the performance of the entire communication link.

As shown in
In some embodiments of the present application, the channel used to piggyback the target uplink control information in the first time unit is at least one of the following channels:
It should be understood that the time unit in the embodiment of the present application may refer to one or more time slots, may also refer to one or more subframes, or may further refer to one or more mini-slots, etc., which is not limited in the present application.
It should be understood that the terminal device transmits the target uplink control information and the target uplink shared channel in the second time unit may mean that the terminal device transmits the target uplink control information and the target uplink shared channel through all the time resources in the second time unit. It may also mean that the terminal device transmits the target uplink control information and the target uplink shared channel through the partial time resources in the second time unit, which is not limited in the present application.
In some possible implementations, the scheduled PUSCH means that the terminal device receives uplink grant (UL grant) information sent by the network device, and determines information such as time domain resources and frequency domain resources for transmitting the PUSCH according to the uplink grant information. In other words, the resources used by the scheduled PUSCH can be considered to be dynamically allocated by the network device to the terminal device.
In some possible implementations, the pre-configured PUSCH means that the terminal device receives radio resource control RRC information sent by the network device, and determines information such as time domain resources and frequency domain resources for transmitting the PUSCH according to the RRC information. In other words, the resources used by the pre-configured PUSCH can be considered to be allocated by the network device to the terminal device in advance.
In some possible implementations, the pre-configured PUSCH means that the terminal device receives radio resource control RRC information sent by the network device, and determines information such as frequency domain resources used to transmit the PUSCH according to the RRC information. The terminal device also receives dynamic scheduling information (for example, an uplink grant) sent by the network device, where the dynamic scheduling information is used to activate or deactivate the pre-configured frequency domain resource used for transmitting PUSCH. In other words, the resources used by the pre-configured PUSCH can also be considered to be allocated by the network device to the terminal device in advance and need to use dynamic signaling to activate or deactivate the pre-configured resources.
For example, the channel used to piggyback the target uplink control information in the first time unit is PUCCH.
For another example, the channel used to piggyback the target uplink control information in the first time unit is a scheduled PUSCH.
For yet another example, the channel used to piggyback the target uplink control information in the first time unit is a pre-configured PUSCH.
In some embodiments of the present application, the target uplink shared channel is a scheduled PUSCH, and/or, the target uplink shared channel is a pre-configured PUSCH.
As an example and not a limitation, taking that the channel used to piggyback the target uplink control information in the first time unit is PUCCH, and the channel used to piggyback the target uplink control information in the second time unit is PUSCH as an example. It can be found that when the terminal device transmits PUCCH and PUSCH on an unlicensed carrier, it can piggyback the uplink control information to be transmitted in the PUCCH (which may be all or part of the uplink control information, for example, HARQ-ACK information) to the PUSCH, that is, the uplink control information (for example, HARQ-ACK information) is enabled to have multiple transmission opportunities. Therefore, the terminal device can transmit the HARQ-ACK information included in the PUCCH on the subsequent PUSCH resource with a certain probability without obtaining the PUCCH transmission opportunity, thereby ensuring the delay and the performance of the entire communication link.
As an example and not a limitation, taking that the channel used to piggyback the target uplink control information in the first time unit is PUCCH, and the channel used to piggyback the target uplink control information in the second time unit is PUSCH as an example. It can be found that when the terminal device transmits multiple PUSCHs on an unlicensed carrier, the same uplink control information (for example, HARQ-ACK information) can be transmitted in the multiple PUSCHs, that is, the uplink control information (for example, HARQ-ACK information) has multiple transmission opportunities, so that the terminal device can transmit the HARQ-ACK information on subsequent PUSCH resources with a certain opportunity without obtaining the previous PUSCH transmission, thereby ensuring the delay and the performance of the entire communication link.
It should be understood that the embodiments of the present application do not specifically limit the type of the channel used to piggyback the target uplink control information in the first time unit and the type of the channel used to piggyback the target uplink control information in the second time unit.
For example, the channel used to piggyback the target uplink control information in the second time unit may also be a scheduled PUSCH.
For another example, the channel used to piggyback the target uplink control information in the second time unit may also be a pre-configured PUSCH.
For another example, the channel used to piggyback the target uplink control information in the second time unit may also be a PUCCH.
As an example and not a limitation, taking that the channel used to piggyback the target uplink control information in the first time unit is PUSCH, and the channel used to piggyback the target uplink control information in the second time unit is PUCCH as an example. It can be found that when the terminal device transmits the PUSCH and PUCCH on It can be found that when the terminal device transmits PUSCH and PUCCH on an unlicensed carrier, the uplink control information to be transmitted in the PUSCH (which can be all or part of the uplink control information, such as HARQ-ACK information) can also be transmitted through the subsequent PUCCH, that is, the uplink control information (for example, HARQ-ACK information) is enabled to have multiple transmission opportunities. Therefore, the terminal device can transmit the HARQ-ACK information included in the PUSCH on the subsequent PUCCH resource with a certain probability without obtaining the PUSCH transmission opportunity, thereby ensuring the delay and the performance of the entire communication link.
In some embodiments of the present application, the target uplink control information includes hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request ACK, HARQ-ACK) information. For example, the HARQ-ACK information corresponding to the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).
In some embodiments of the present application, the target uplink control information includes at least one of HARQ-ACK information, channel state information (Channel State Information, CSI), and scheduling request (Scheduling request, SR) information. Where, the channel state information includes at least one of rank indication (Rank Indication, RI) and precoding matrix indicator (Precoding Matrix Indicator, PMI) and a channel quality indicator (Channel Quality Indicator, CQI).
It should be understood that the embodiment of the present application only uses the above uplink control information as an example, and the embodiment of the present application is not limited to this. For example, the uplink control information in the embodiment of the present application may also include HARQ process identification ID, terminal device ID, uplink assignment index (Uplink assignment index, UAI), etc.
In some possible implementations, the terminal device transmitting the target uplink control information in the second time unit may be that the terminal device transmits all the information of the target uplink control information in the second time unit, and may also be that the terminal device transmits part information of the target uplink control information in the second time unit, which is not limited in the present application.
In some possible implementations, since the embodiment of the present application mainly provides multiple transmission opportunities in the time domain for the target uplink control information, when the target uplink control information includes multiple types of uplink control information, the multiple transmission opportunities may only be provided to the uplink control information with higher priority in the target uplink control information. For example, the target uplink control information includes first uplink control information and second uplink control information. A priority of the first uplink control information is higher than that of the second uplink control information. The terminal device may transmit the first uplink control information and the second uplink control information in the first time unit, and transmit the first uplink control information, rather than transmitting the second uplink control information in the second time unit.
In some possible implementations, the HARQ-ACK information in the uplink control information has a higher priority than the CSI. In some possible implementations, the priority of the scheduling request information in the uplink control information is higher than the CSI. In some possible implementations, the priority of the HARQ-ACK information corresponding to the PDSCH firstly transmitted in the uplink control information is higher than that of the HARQ-ACK information corresponding to the PDSCH transmitted later.
In some possible implementations, the second time unit includes at least two time units, and the target uplink control information is located in the last time unit or the penultimate time unit of the at least two time units.
In some embodiments of the present application, the first time unit and the second time unit are continuous in the time domain.
In some embodiments of the present application, the first time unit and the second time unit are not continuous in the time domain.

In some embodiments of the present application, the indication information is further used to indicate that the terminal device can transmit the target uplink control information in the second time unit.
In some embodiments of the present application, the indication information is physical layer signaling, and/or, the indication information is higher layer signaling.
It should be understood that the indication information may be a explicit indication or an implicit indication, and it may be a direct indication or an indirect indication, which are not limited in the present application.
For example, the indication information is used to indicate that the terminal device can transmit the target uplink control information in the second time unit, and it may be: the indication information is used to indicate that the terminal device can transmit an uplink control channel in the second time unit, and the content transmitted in the uplink control channel includes the target uplink control information.
It should be understood that the embodiment of the present application does not limit the specific form of the indication information. For example, the indication information may include at least one piece of information.
For example, the indication information includes first information and second information, and the first information is physical layer signaling (for example, downlink control information), which is used to indicate that the terminal device can transmit the target uplink control information in the first time unit, and can transmit the target uplink shared channel in the second time unit. The second information is high-level signaling (for example, RRC information or media access control MAC information), which is used to indicate that the terminal device can transmit the target uplink control information in the second time unit.
For another example, the indication information includes first information and second information, where the first information is used to indicate that the terminal device can transmit the target uplink control information in the first time unit and the second time unit, and the second information is used to indicate that the terminal device can transmit the target uplink shared channel in the second time unit. Where, the first information may be physical layer signaling or high layer signaling, and the second information may also be physical layer signaling or high layer signaling.

It should be understood that the terminal device has obtained the channel using right of the second time unit, which may be that the terminal device performs channel detection before the second time unit to obtain the channel using right and may also be that the terminal device has obtained the channel using right of the third time unit and the third time unit and the second time unit are continuous in the time domain, or the second time unit does not need to perform channel detection, or other cases, which is not limited in the present application. It should also be understood that the situation in which the terminal device obtains the channel using right of other time units is similar to the situation in which the channel using right of the second time unit is obtained, and will not be repeated.

For example, in the case that the terminal device has obtained the channel using right of the first time unit and the channel using right of the second time unit, the terminal device may also transmit the target uplink control information only in the first time unit or the second time unit.
In some embodiments of the present application, before the terminal device transmits the target uplink control information and the target uplink shared channel in the second time unit, the terminal device does not obtain the channel using right of the first time unit.

As shown in
In other words, the network device in the embodiment of the present application may indicate the terminal device to transmit the PUCCH in the second time unit through indication information, that is, the second time unit is a resource allocated to the terminal device to transmit the PUCCH. However, since the terminal device again needs to transmit the PUSCH in the second time unit, a collision between the PUCCH and the PUSCH will occur in the second time unit.
In the embodiment of the present application, the terminal device may transmit the first HARQ-ACK information on the PUSCH in a multiplexing transmission manner in the second time unit.

Specifically, when the terminal device has obtained the channel using right of the first time unit, the existing information transmission method may be adopted. When the terminal device does not obtain the using right of the first time unit, the terminal device transmits the target uplink control information and the target uplink shared channel in the second time unit. Through the above technical solutions, the transmission success rate of the uplink control information can be effectively ensured.
In some embodiments of the present application, the channel used to piggyback the target uplink control information in the first time unit is a physical uplink control channel PUCCH; or, the channel used to piggyback the target uplink control information in the first time unit is a scheduled physical uplink shared channel PUSCH; or, the channel used to piggyback the target uplink control information in the first time unit is pre-configured PUSCH.
In some embodiments of the present application, the target uplink shared channel is a scheduled physical uplink shared channel PUSCH, and/or, the target uplink shared channel is a pre-configured PUSCH.
In some embodiments of the present application, before the terminal device transmits the target uplink control information and the target uplink shared channel in the second time unit, the terminal device receives indication information sent by a network device, where the indication information is used to indicate that the terminal device may transmit the target uplink control information in the first time unit, and may transmit the target uplink shared channel in the second time unit.

In the embodiment of the present application, the terminal device may perform channel detection on the unlicensed carrier before the first time unit. If the channel detection is successful, the terminal device may transmit the first HARQ-ACK information in the first time unit, and not transmit the first HARQ-ACK information on the last time unit in the second time unit. The network device receives the first HARQ-ACK information sent by the terminal device in the first time unit, and receives the PUSCH sent by the terminal device in the second time unit.
In some possible implementations, in the embodiment shown in
It can be found that, in the embodiment of the present application, when the terminal device transmits PUCCH and PUSCH on continuous time units in the time domain on the unlicensed carrier, and when the terminal device has obtained the channel using rights of the first time unit and the second time unit, transmitting the target uplink control information in the first time unit and transmitting the target uplink shared channel in the second time unit may be preferentially used, and =the use of sending uplink control information on the PUSCH is avoided, thereby ensuring the transmission performance of the PUSCH in the second time unit. When the terminal device does not obtain the channel using right of the first time unit and obtains the channel using right of the second time unit, the target uplink control information and the target uplink shared channel may be transmitted in the second time unit, so that the target uplink control information has multiple transmission opportunities in the time domain, thereby ensuring the transmission performance of the target uplink control information.
