Description

Wireless communication method, terminal device and network device

Technical Field

The embodiment of the application relates to the field of communication, and more particularly relates to a wireless communication method, terminal equipment and network equipment.

Background

The New air interface (NR) does not support simultaneous transmission of two overlapping uplink channels, e.g. a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and PUSCH, PUSCH and a physical uplink control channel (Physical Uplink Control Channel, PUCCH). For two overlapped uplink channels, a conflict resolution mechanism is needed to be used for processing, so that the reliability of data transmission is ensured. In general, the terminal device may perform collision resolution on the resources that collide based on a collision resolution mechanism of a priority (lch-based prioritisation) of the logical channel or based on uplink skip (UL skip) to ensure normal transmission of data.

However, when the logical channel-based priority (lch-based priority) and uplink skip (UL skip) are configured at the same time, there occurs a case where, for one uplink grant, according to the logical channel-based priority, it is low priority, MAC PDU generation is not required, but according to the uplink skip, it is possible to be high priority (i.e., MAC PDU generation is required), and it is apparent that the results caused by these two collision resolution mechanisms are contradictory to each other, thereby causing data transmission failure. Therefore, the present application needs to further improve the collision resolution mechanism to improve the reliability of data transmission.

FIG. 1 is an example of a system framework of an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

In order to facilitate understanding of the scheme provided by the present application, the following describes related contents based on the priority of the logical channel, the priority of the physical layer and uplink skip.

Priority based on logical channels:

for a MAC entity, if logical channel based priority (lch-based prioritisation) is configured, the priority of an uplink grant (uplink grant) is determined based on the highest priority among the priorities of logical channels multiplexed in MAC PDUs (i.e. MAC PDUs to be transmitted are already stored in the HARQ buffer) or data available for multiplexing (i.e. MAC PDUs to be transmitted are not stored in the HARQ buffer) (For the MAC entity configured with lch-based prioritisation, priority of an uplink grant is determined by the highest priority among priorities of the logical channels that are multiplexed (i.e. the MAC PDU to transmit is already stored in the HARQ buffer) or have data available that can be multiplexed (i.e. the MAC PDU to transmit is not stored in the HARQ buffer) in the MAC PDUs). If an uplink grant has no data of a multiplexed logical channel or no data of a logical channel in the MAC PDU can be multiplexed in the MAC PDU, the priority of the uplink grant is lower than the priority of an uplink grant in which any logical channel data is multiplexed or can be multiplexed in the MAC PDU (The priority of an uplink grant for which no data for logical channels is multiplexed or can be multiplexed in the MAC PDU is lower than either the priority of an uplink grant for which data for any logical channels is multiplexed or can be multiplexed in the MAC PDU).

Physical layer priority:

in NR Rel-16, in order to better support Ultra-high reliability low latency communication (URLLC, ultra-reliable low latency) service, a high priority and a low priority are introduced in the physical layer for the uplink channel, a priority index (priority index) 0 indicates a low priority, and a priority index 1 indicates a high priority. For the configured uplink channel transmission, the corresponding physical layer priority is configured by the network side through RRC signaling, and for the dynamically scheduled uplink channel transmission, the corresponding physical layer priority is indicated by a priority indication (priority indicator) carried in DCI sent by the network side.

Uplink skip (UL skip):

for one MAC entity, when no logical channel based priority (lch-based prioritisation) is configured:

if the skip uplink active transmission parameter (enhanced uplink txdate) is configured to be true (true), and the uplink grant indicated to the hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) entity is scrambled by the cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI), if the first condition is met, no MAC PDU is generated for the HARQ entity.

If the skipped uplink configuration transmission parameter (enhanced skip uplink txconfiguration) is configured to be true (true), and the uplink grant indicated to the HARQ entity is configured uplink grant, if the first condition is satisfied, no MAC PDU is generated for the HARQ entity.

As an example, the first condition is:

1. if there is no UCI to multiplex on this PUSCH transmission according to TS 38.213; and is also provided with

2. If there is no aperiodic channel state information (Channel State Information, CSI) request on this PUSCH transmission; and is also provided with

3. If this MAC PDU contains 0 MAC SDUs; and is also provided with

4. If this MAC PDU contains only periodic buffer status reports (Buffer Status Report, BSR) and no data is available for any logical channel group (Logical Channel Group, LCG), or this MAC PDU contains only padding (padding) BSR.

It can be seen that if the skipped uplink active transmission parameter is configured to be true or if the skipped uplink configured transmission parameter is configured to be true, based on condition 1 in the first condition, if there is uplink control information (Uplink Control Information, UCI) multiplexed on PUSCH corresponding to one uplink grant for transmission, the priority of one uplink grant is high, that is, MAC PDU needs to be generated for the one uplink grant.

As shown in fig. 2, even if the MAC PDU corresponding to the DG/CG PUSCH has no multiplexed data, because UCI (i.e., a physical uplink control channel (Physical Uplink Control Channel, PUCCH)) is multiplexed and transmitted on the DG/CG PUSCH, the MAC layer generates the MAC PDU to the physical layer, so as to ensure that UCI can be multiplexed and transmitted on the DG/CG PUSCH, and avoid blind detection of PUSCH and PUCCH by the base station.

NR does not support simultaneous transmission of two overlapping uplink channels (including PUSCH and PUSCH, PUSCH and PUCCH), and processing by a collision resolution mechanism is required for the two overlapping uplink channels to ensure reliability of data transmission. In general, the terminal device may perform collision resolution on the collided resources based on a collision resolution mechanism of a priority (lch-based prioritisation) of the logical channel or a collision resolution mechanism configured based on uplink skip (UL skip) to ensure normal transmission of data.

The collision resolution mechanism provided by the present application is described below in connection with logical channel based priorities, physical layer priorities, and uplink skipping as described above.

For the conflict solution mechanism based on the priority of the logic channel, if two PUSCH resources corresponding to two uplink grants (uplink grant) overlap, the conflict solution mechanism can be implemented in the media access control (Media Access Control, MAC) layer, that is, the MAC layer only generates one MAC protocol data unit (Protocol Data Unit, PDU) to the physical layer; i.e. a collision resolution mechanism can be designed based on the priorities of the logical channels. Specifically, if the priority based on the logical channel is configured (lch-based priority), the MAC entity takes the uplink grant with low priority as the non-priority uplink grant (de-prioritized uplink grant), and takes the uplink grant with high priority as the priority uplink grant (prioritized uplink grant), i.e., the transmission of the channel with high priority is preferentially guaranteed. If the logical channel-based priority (lch-based priority) is not configured, the MAC layer generates a MAC PDU corresponding to a Dynamic Grant (DG) without generating a MAC PDU corresponding to a Configured Grant (CG), i.e., transmission of a channel that is limited to guarantee dynamic scheduling. If uplink PUSCH and PUCCH resources overlap, a conflict resolution mechanism can be realized in a physical layer; i.e. a collision resolution mechanism can be designed based on physical layer priorities. Specifically, when uplink channels with different priorities overlap in the time domain, the terminal only transmits the high-priority channel, and the low-priority channel is discarded, that is, the transmission of the high-priority channel is limited. When PUSCH and PUCCH physical layer priorities are the same, PUCCH may be multiplexed for transmission on PUSCH.

In addition, the terminal may also resolve a collision caused by overlapping PUSCH and PUCCH resources based on a collision resolution mechanism configured by uplink skip (UL skip). Specifically, for one MAC entity, when no priority (lch-based priority) based on a logical channel is configured, if a skip uplink active transmission parameter is configured to be true or if a skip uplink configuration transmission parameter is configured to be true, based on condition 1 in the first condition, if uplink control information (Uplink Control Information, UCI) is multiplexed on a PUSCH corresponding to one uplink grant for transmission, the priority of one uplink grant is high priority, that is, MAC PDU needs to be generated for the one uplink grant. In other words, even if the MAC PDU corresponding to the PUSCH has no data to be multiplexed (i.e., data to be transmitted), since there is UCI to be multiplexed and transmitted on the PUSCH, the MAC layer generates the MAC PDU to the physical layer, so as to ensure that UCI can be transmitted on the PUSCH, and avoid blind detection of PUSCH and PUCCH by the base station.

It follows that when the logical channel based priority (lch-based priority) and uplink skip (UL skip) configurations are configured simultaneously, there occurs a case that, for one uplink grant, according to the logical channel based priority, it is low priority, no MAC PDU needs to be generated, but according to the uplink skip, it is possible to be high priority (i.e. MAC PDU needs to be generated), and it is obvious that the results caused by these two collision resolution mechanisms are contradictory to each other, thereby causing data transmission failure.

As shown in fig. 3, according to the configured priority based on the logical channel, the priority of the corresponding uplink grant of PUSCH 1 is lower than the priority of the corresponding uplink grant of PUSCH 2, i.e. the uplink grant corresponding to PUSCH 1 is a non-priority uplink grant, and the MAC layer does not generate a MAC PDU for the uplink grant corresponding to PUSCH 1; according to the configured uplink skip, the PUCCH and PUSCH 1 overlap (overlap), and the PUCCH is multiplexed (multiplexed) to PUSCH 1 for transmission, so that the MAC PDU needs to be generated for the uplink grant corresponding to PUSCH 1; obviously, based on the priority of the logic channel and uplink skip, whether the MAC PDU is generated for the uplink grant corresponding to the PUSCH 1 is determined, and contradictory results exist.

It should be noted that, when whether to generate the MAC PDU for the uplink grant corresponding to the PUSCH 1 is determined based on the priority of the logical channel and the uplink skip, there are two contradictory results; if these two results are simply screened, or if the priorities of the logical channels and the priorities of the upstream skips are simply designed, the data transmission reliability is improved and the compatibility of controlling the power consumption of the network device is too low.

For example, if the priority of uplink skipping is higher than the priority based on the priority of logical channels, the MAC entity will generate a MAC PDU for PUSCH 1 (even if its corresponding priority of uplink grant is low), which will result in the failure of transmission of orange PUSCH 2 (corresponding to high logical channel priority) data, against the working principle of intra-UE priority (intra-UE prioritization), i.e. against the working principle of transmission of data/channels with priority guaranteed to high priority; if the priority based on the priority of the logical channel is higher than the priority of uplink skip, the MAC entity will generate a MAC PDU for the uplink grant corresponding to PUSCH 2, PUSCH 1 cannot transmit, UCI on PUCCH is transmitted or UCI on (drop) PUCCH is discarded, however from the perspective of the base station, if UCI on PUCCH is not determined to be transmitted on PUSCH 1, the network device needs to perform blind detection on both PUSCH 1 and PUCCH to determine the transmission resource of UCI, which will result in increased power consumption of the base station.

Based on the above, the application provides a wireless communication method, terminal equipment and network equipment, which can further perfect a conflict resolution mechanism, so that the reliability of data transmission can be improved, blind detection of the network equipment can be reduced as much as possible, and the power consumption of the network equipment can be reduced as much as possible.

Fig. 4 is a schematic flow chart of a wireless communication method 200 provided by an embodiment of the present application. The method 200 may be performed by a terminal device. For example, a terminal device as shown in fig. 1. Of course, the method 200 may also be performed by a MAC entity and/or a physical layer in the terminal device, which is not particularly limited by the present application.

As shown in fig. 4, the method 200 may include some or all of the following:

s210, determining a priority of a first uplink grant or determining whether to generate a MAC PDU for the first uplink grant according to at least one of:

whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels or not, or whether the data of the logical channels can be multiplexed in the MAC PDU corresponding to the first uplink grant or not;

whether UCI is multiplexed on the second PUSCH.

In other words, in the case that the time domain resources of the first PUSCH and the second PUSCH overlap or partially overlap, the priority of the first uplink grant may be determined or whether the MAC PDU is generated for the first uplink grant may be determined according to at least one of the priority of the first PUSCH, the priority of the second PUSCH, whether the MAC PDU corresponding to the first uplink grant has data of a multiplexed logical channel or whether the data of a logical channel may be multiplexed in the MAC PDU corresponding to the first uplink grant, whether UCI is multiplexed on the first PUSCH, and whether UCI is multiplexed on the second PUSCH. Wherein the first PUSCH is scheduled or associated with the first uplink grant.

Briefly, the terminal device may determine the priority of the first uplink grant or determine whether to generate a MAC PDU for the first uplink grant by comprehensively considering the physical layer priority, the priority based on the logical channel, and the uplink skip. For example, for different situations, a physical layer priority is determined, based on the priority of the logical channel and an optimal configuration in uplink skipping, and further, based on the optimal configuration, a priority of a first uplink grant is determined or whether to generate a MAC PDU for the first uplink grant is determined. In other words, the physical layer priority, the priority based on the logical channel, and the execution order or priority of the uplink skip are different for different cases.

In this embodiment, determining the priority of a first uplink grant or determining whether to generate a MAC PDU for the first uplink grant according to at least one of the priority of a first PUSCH, the priority of a second PUSCH, whether there is multiplexing of data of a logical channel in the MAC PDU corresponding to the first uplink grant or whether there is multiplexing of uplink control information UCI in the MAC PDU corresponding to the first uplink grant, whether there is multiplexing of UCI in the first PUSCH, and whether there is multiplexing of UCI in the second PUSCH; equivalently, a judging factor for determining the priority of the first uplink grant or determining whether to generate the MAC PDU for the first uplink grant is reconstructed, so that a contradictory result is avoided when determining the priority of the first uplink grant or determining whether to generate the MAC PDU for the first uplink grant due to the priority of the logical channel and uplink skip at the same time, and further, a conflict resolution mechanism can be further perfected and the reliability of data transmission is improved.

In this embodiment, the priority of the first PUSCH may be a physical layer priority of the first PUSCH, and the priority of the second PUSCH may be a physical layer priority of the second PUSCH. Optionally, for the configured PUSCH transmission, the corresponding physical layer priority is configured by the network side through RRC signaling; for dynamically scheduled PUSCH transmission, the corresponding physical layer priority is indicated by a priority indication (priority indicator) carried in DCI sent by the network side. In other words, the physical layer priority corresponding to the first PUSCH is determined according to a priority indication field in the downlink control information sent by the network side, or determined according to physical layer priority information configured by the network side; specifically, after determining the physical layer priority corresponding to the first PUSCH, the physical layer may indicate the physical layer priority to the MAC layer.

Furthermore, whether UCI is multiplexed on the first PUSCH may be understood as: whether there is PUCCH multiplexed on the first PUSCH or whether there is UCI to be multiplexed (i.e., to be multiplexed) on the first PUSCH; similarly, whether UCI is multiplexed on the second PUSCH may be understood as: whether there is PUCCH multiplexed on the second PUSCH or whether there is UCI to be multiplexed (i.e., to be multiplexed) on the second PUSCH. Optionally, the priority of the PUCCH multiplexed on the first PUSCH is equal to the priority of the first PUSCH; similarly, the priority of the PUCCH multiplexed for transmission on the second PUSCH is equal to the priority of the second PUSCH. In addition, in the present application, if it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant; that is, it is determined that the second uplink grant has a lower priority than the first uplink grant, or that no MAC PDU is generated for the second uplink grant.

In addition, whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels or whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels may be multiplexed in the MAC PDU corresponding to the first uplink grant, which may include: before performing uplink skip detection (check), whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels or whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels can be multiplexed in the MAC PDU corresponding to the first uplink grant; but the present application is not limited thereto.

The following describes an exemplary implementation manner of determining the priority of the first uplink grant or determining whether to generate a MAC PDU for the first uplink grant according to the priority of the first PUSCH, the priority of the second PUSCH, and whether UCI is multiplexed for transmission on the first PUSCH:

in some embodiments, the S210 may include:

if the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH and UCI is multiplexed on the first PUSCH, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant.

In other words, if the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH and UCI is multiplexed on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be a priority uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

Of course, in other alternative embodiments, if the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, or UCI is multiplexed on the first PUSCH, it may also be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU may be generated for the first uplink grant. In other words, the priority of the first uplink grant may be determined based on only the physical layer priority or the uplink skip, or whether to generate the MAC PDU for the first uplink grant, which is not specifically limited by the embodiment of the present application.

As an example, the S210 may include:

if the index of the priority of the first PUSCH is 1, UCI is multiplexed and transmitted on the first PUSCH, and the index of the priority of the second PUSCH is 0, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant.

In other words, if the index of the priority of the first PUSCH is 1, UCI is multiplexed on the first PUSCH, and the index of the priority of the second PUSCH is 0, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be a priority uplink grant. Or if the priority of the first PUSCH is high, UCI is multiplexed and transmitted on the first PUSCH, and the priority of the second PUSCH is low, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

The following exemplarily describes an implementation manner of determining the priority of the first uplink grant or determining whether to generate a MAC PDU for the first uplink grant according to the priority of the first PUSCH, the priority of the second PUSCH, whether UCI is multiplexed to be transmitted on the first PUSCH, and whether UCI is multiplexed to be transmitted on the second PUSCH:

in some embodiments, the S210 may include:

if the priority of the first PUSCH is equal to the priority of the second PUSCH, UCI is multiplexed and transmitted on the first PUSCH, and no UCI is multiplexed and transmitted on the second PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant.

In other words, if the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is transmitted on the first PUSCH and no UCI is transmitted on the second PUSCH, the priority of the first uplink grant is determined as the highest priority or the first uplink grant is determined as a priority uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

Of course, in other alternative embodiments, if the priority of the first PUSCH is equal to the priority of the second PUSCH, or if there is UCI multiplexing transmitted on the first PUSCH and no UCI multiplexing is transmitted on the second PUSCH, it may also be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or MAC PDUs may be generated for the first uplink grant. In other words, the priority of the first uplink grant may be determined based on only the physical layer priority or the uplink skip, or whether to generate the MAC PDU for the first uplink grant, which is not specifically limited by the embodiment of the present application.

As an example, the S210 may include:

if the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 1, UCI is multiplexed and transmitted on the first PUSCH, and no UCI is multiplexed and transmitted on the second PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant.

In other words, if the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 1, and UCI is transmitted on the first PUSCH and no UCI is transmitted on the second PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be a priority uplink grant. Or if the priority of the first PUSCH is high, UCI is multiplexed and transmitted on the first PUSCH, and the priority of the second PUSCH is high, and no UCI is multiplexed and transmitted on the second PUSCH, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

As another example, the S210 may include:

if the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, UCI is multiplexed on the first PUSCH and no UCI is to be multiplexed on the second PUSCH, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant.

In other words, if the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, and UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be a priority uplink grant. Or if the priority of the first PUSCH is low, UCI is multiplexed and transmitted on the first PUSCH, and the priority of the second PUSCH is low, and no UCI is multiplexed and transmitted on the second PUSCH, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating a MAC PDU for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

The following describes, as examples, an implementation manner of determining whether a first uplink grant has a priority or determining whether to generate a MAC PDU for the first uplink grant according to whether the MAC PDU corresponding to the first uplink grant has data of a multiplexing logical channel or whether the MAC PDU corresponding to the first uplink grant has data of a multiplexing logical channel and may be multiplexed in the MAC PDU corresponding to the first uplink grant, a priority of a first PUSCH, a priority of a second PUSCH, whether UCI is multiplexed and transmitted on the first PUSCH:

in some embodiments, the S210 may include:

if the data with multiplexing logical channels or the data with logical channels in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH for transmission, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

Of course, in other alternative embodiments, if the data with the multiplexed logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH; or if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and UCI is multiplexed and transmitted on the first PUSCH, it may also be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant. In other words, the priority of the first uplink grant may be determined based on only the physical layer priority or the uplink skip, or whether to generate the MAC PDU for the first uplink grant, which is not specifically limited by the embodiment of the present application.

As an example, the S210 may include:

if the data with multiplexing logical channels or the data with logical channels in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH is 1, and UCI multiplexing is transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH is 1, and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. Or if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is high, and UCI is multiplexed on the first PUSCH for transmission, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating the MAC PDU for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

As another example, the S210 may include:

if the data with multiplexing logical channels or the data with logical channels in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, and UCI multiplexing is transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the MAC PDU corresponding to the first uplink grant has multiplexed logical channel data or logical channel data, which can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. Or, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH and the priority of the second PUSCH are both low, and UCI multiplexing is transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

Further, the second uplink grant satisfies any one of the following conditions:

the highest priority of the priorities of the logic channels multiplexed in the MAC PDU corresponding to the second uplink grant or the highest priority of the priorities of the logic channels with data multiplexing in the MAC PDU corresponding to the second uplink grant is the same as the highest priority of the priorities of the logic channels multiplexed in the MAC PDU corresponding to the first uplink grant or the highest priority of the priorities of the logic channels with data multiplexing in the MAC PDU corresponding to the first uplink grant;

the highest priority of the priorities of the logic channels multiplexed in the second uplink grant corresponding MAC PDU or the highest priority of the priorities of the logic channels with data multiplexed in the second uplink grant corresponding MAC PDU is smaller than or equal to a first threshold value than the highest priority of the priorities of the logic channels multiplexed in the first uplink grant corresponding MAC PDU or the highest priority of the priorities of the logic channels with data multiplexed in the first uplink grant corresponding MAC PDU.

As an example, the highest priority among the priorities of the logical channels multiplexed in the MAC PDU corresponding to the second uplink grant is higher than the priority of the logical channel multiplexed in the MAC PDU corresponding to the first uplink grant by a difference less than or equal to a first threshold; as another example, the highest priority among the priorities of the logical channels multiplexed in the MAC PDU corresponding to the second uplink grant is higher than the highest priority among the priorities of the logical channels having data that can be multiplexed in the MAC PDU corresponding to the first uplink grant by a difference value less than or equal to the first threshold. As another example, there is a highest priority among priorities of logical channels in which data can be multiplexed in the MAC PDU corresponding to the second uplink grant, and a higher difference value is less than or equal to a first threshold than a highest priority among priorities of logical channels in which data can be multiplexed in the MAC PDU corresponding to the first uplink grant.

In this embodiment, by constructing the condition that the second uplink grant needs to meet, blind detection between PUSCH and PUCCH by the network device can be avoided as much as possible on the basis of avoiding discarding data with higher priority of the logical channel as much as possible, so as to reduce power consumption of the network device. Accordingly, the situation that the MAC PDU corresponding to the first PUSCH is not generated and is transmitted to the physical layer can be reduced, and further, the processing of the physical layer on the multiplexed UCI can be reduced as much as possible, for example, the physical layer is prevented from directly discarding the UCI as much as possible, so as to improve service performance and transmission efficiency.

As an example, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and the UCI is multiplexed on the first PUSCH, and no UCI is multiplexed on the second PUSCH, and the highest priority of the priorities of the logical channels multiplexed in the MAC PDU corresponding to the second uplink grant or the highest priority of the priorities of the logical channels with the data can be multiplexed in the MAC PDU corresponding to the second uplink grant, the priority of the first uplink grant is determined to be higher than the priority of the second uplink grant, or the highest priority of the priorities of the logical channels with the data can be multiplexed in the MAC PDU corresponding to the first uplink grant is determined to be the same, or the MAC PDU corresponding to the first uplink grant is generated.

As another example, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and the UCI is multiplexed on the first PUSCH, and no UCI is multiplexed on the second PUSCH, and the highest priority of the priorities of the logical channels multiplexed in the MAC PDU corresponding to the second uplink grant or the highest priority of the priorities of the logical channels multiplexed with the data can be multiplexed in the MAC PDU corresponding to the second uplink grant is determined to be higher than the priority of the second uplink grant or the highest priority of the priorities of the logical channels multiplexed with the data can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the difference value is smaller than or equal to a first threshold, the first uplink grant is determined to be higher than the priority of the second uplink grant, or the first uplink grant is generated for the first MAC PDU.

It should be understood that the value or the value range of the first threshold is not specifically limited in the embodiment of the present application. Optionally, the first threshold may be predefined, may be indicated by the network device, or may be determined by negotiation between the terminal device and the network device. Alternatively, the first threshold may be an integer greater than or equal to 0. It should be noted that, in the embodiment of the present application, the "preset" may be implemented by pre-storing a corresponding code, a table, or other manners that may be used to indicate relevant information in a device (including, for example, a terminal device and a network device), and the specific implementation manner of the present application is not limited. Such as preset, may refer to what is defined in the protocol. Alternatively, the "protocol" may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied to a future communication system, which is not particularly limited by the present application. The term "indication" related in the embodiment of the present application may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B.

In some embodiments, the S210 may include:

if the data of the multiplexing logic channel or the data of the logic channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH is 0, determining whether the first uplink grant is a priority uplink grant or determining whether to generate the MAC PDU for the first uplink grant according to the highest priority among the priorities of the logic channels multiplexed in the MAC PDU corresponding to the first uplink grant or the highest priority among the priorities of the logic channels in which the data can be multiplexed in the MAC PDU corresponding to the first uplink grant.

In other words, if the data with the multiplexed logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is low, determining whether the first uplink grant is the priority uplink grant or determining whether to generate the MAC PDU for the first uplink grant according to the highest priority among the priorities of the multiplexed logical channels or the highest priority among the priorities of the logical channels with the data can be multiplexed in the MAC PDU corresponding to the first uplink grant. In this embodiment, for the case that the priority of the first PUSCH is low, the method is separately designed to determine whether the first uplink grant is a priority uplink grant or whether to generate a MAC PDU for the first uplink grant according to the highest priority of priorities of logical channels multiplexed in the MAC PDU corresponding to the first uplink grant or the highest priority of priorities of logical channels having data that can be multiplexed in the MAC PDU corresponding to the first uplink grant; that is, when the priority of the first PUSCH is high priority or low priority, it is avoided that a unified processing manner is adopted to determine whether the first uplink grant is a priority uplink grant or whether to generate a MAC PDU for the first uplink grant, which is beneficial to improving reliability of data transmission as much as possible on the basis of reducing power consumption.

In some embodiments, the S210 may include:

if the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH for transmission, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the MAC PDU corresponding to the first uplink grant has no multiplexed logical channel data or no logical channel data multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

As an example, the S210 may include:

if the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH is 1, and UCI is multiplexed and transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the MAC PDU corresponding to the first uplink grant has no multiplexed logical channel data or no logical channel data, which may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH is 1 and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. Or if the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is high, and UCI is multiplexed on the first PUSCH for transmission, determining that the priority of the first uplink grant is higher than the priority of the second uplink grant, or generating the MAC PDU for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

As another example, the S210 may include:

if the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the first uplink grant can be multiplexed in the MAC PDU corresponding to the first uplink grant, and the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, and UCI multiplexing is transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In other words, if the MAC PDU corresponding to the first uplink grant has no multiplexed logical channel data or no logical channel data, and the index of the priority of the first PUSCH and the index of the priority of the second PUSCH are both 0, and UCI is multiplexed and transmitted on the first PUSCH, the priority of the first uplink grant is determined to be the highest priority or the first uplink grant is determined to be the priority uplink grant. Or, if the data without multiplexing the logical channel in the MAC PDU corresponding to the first uplink grant or the data without multiplexing the logical channel in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH and the priority of the second PUSCH are both low, and UCI is multiplexed and transmitted on the first PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant. In this embodiment, the priority of the first uplink grant is directly determined as the highest priority, so that not only can the transmission reliability of the first PUSCH be improved, but also blind detection of the PUSCH and the PUCCH by the network device can be avoided, thereby reducing the power consumption of the network device.

Further, in the case where the priority of the second PUSCH is equal to the priority of the first PUSCH, the second uplink grant satisfies any one of the following conditions:

no UCI multiplexing is transmitted on the second PUSCH;

the data without multiplexing the logic channel or the data without the logic channel in the MAC PDU corresponding to the second uplink grant can be multiplexed in the MAC PDU corresponding to the second uplink grant;

no UCI is multiplexed and transmitted on the second PUSCH, and data without multiplexing a logical channel in the MAC PDU corresponding to the second uplink grant or data without a logical channel may be multiplexed in the MAC PDU corresponding to the second uplink grant.

As an example, if the MAC PDU corresponding to the first uplink grant has no multiplexed logical channel data or no logical channel data multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

As another example, if the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the first uplink grant may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH for transmission, and the data without multiplexing the logical channel or the data without the logical channel in the MAC PDU corresponding to the second uplink grant may be multiplexed in the MAC PDU corresponding to the second uplink grant, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

As another example, if no data of a multiplexing logical channel or no data of a logical channel in the MAC PDU corresponding to the first uplink grant may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, and no data of a multiplexing logical channel or no data of a logical channel in the MAC PDU corresponding to the second uplink grant may be multiplexed in the MAC PDU corresponding to the second uplink grant, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

In some embodiments, the method 200 may further comprise:

receiving configuration information;

the skipped uplink active transmission parameter (enhanced skip uplink txdata) in the configuration information is true, or the skipped uplink configuration transmission parameter (enhanced skip uplink txconfiguration) in the configuration information is true.

In other words, in case that the skipped uplink active transmission parameter in the configuration information is true or the skipped uplink configuration transmission parameter in the configuration information is true, determining the priority of the first uplink grant or determining whether to generate a MAC PDU for the first uplink grant according to at least one of: priority of the first PUSCH; priority of the second PUSCH; whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logic channels or not, or whether the data of multiplexing logic channels or not can be multiplexed in the MAC PDU corresponding to the first uplink grant; whether UCI is multiplexed for transmission on the first PUSCH; whether UCI is multiplexed on the second PUSCH.

Of course, in other alternative embodiments, whether the first uplink grant is prioritized or whether the MAC PDU is generated for the first uplink grant may be determined according to whether the MAC PDU corresponding to the first uplink grant has data of multiplexing logical channels or whether the data of multiplexing logical channels can be multiplexed in the MAC PDU corresponding to the first uplink grant, the priority of the first PUSCH, the priority of the second PUSCH, whether UCI is multiplexed on the first PUSCH, and whether UCI is multiplexed on the second PUSCH.

For example, if the data with the multiplexing logical channel or the data with the logical channel in the MAC PDU corresponding to the first uplink grant may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant. For another example, if the data without multiplexing the logical channel or the data without multiplexing the logical channel in the MAC PDU corresponding to the first uplink grant may be multiplexed in the MAC PDU corresponding to the first uplink grant, and the priority of the first PUSCH is equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, it is determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or the MAC PDU is generated for the first uplink grant.

The following describes the solution provided by the present application with reference to specific examples.

Example 1:

in this embodiment, if the priority of the first PUSCH is greater than or equal to the priority of the second PUSCH, and UCI is multiplexed on the first PUSCH, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, it is always determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant.

As an example, assume that the priority of the first PUSCH is a high priority; at this time, as long as UCI is multiplexed on the first PUSCH, it may be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or MAC PDUs may be generated for the first uplink grant.

Fig. 5 and 6 are examples of applicable scenarios of a wireless communication method provided by an embodiment of the present application.

As shown in fig. 5, the terminal device is configured or scheduled to transmit a first PUSCH (i.e., high priority PUSCH (HP PUSCH)); wherein the HP PUCCH to be transmitted and the first PUSCH overlap (overlap), i.e. HP PUCCH multiplexing is transmitted on the first PUSCH; furthermore, the second PUSCH to be transmitted (i.e. high priority PUSCH (HP PUSCH)) overlaps with the first PUSCH, i.e. the priority of the first PUSCH is equal to the priority of the second PUSCH. At this time, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, the priority of the first uplink grant corresponding to the first PUSCH in which UCI (i.e., HP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH, i.e., the MAC entity generates a MAC PDU for the first PUSCH and does not generate a MAC PDU for the second PUSCH.

As shown in fig. 6, the terminal device is configured or scheduled to transmit a first PUSCH (i.e., high priority PUSCH (HP PUSCH)); wherein the HP PUCCH to be transmitted and the first PUSCH overlap (overlap), i.e. HP PUCCH multiplexing is transmitted on the first PUSCH; further, the second PUSCH (i.e., low priority PUSCH (LP PUSCH)) to be transmitted overlaps with the first PUSCH, i.e., the priority of the first PUSCH is greater than the priority of the second PUSCH. At this time, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, the priority of the first uplink grant corresponding to the first PUSCH in which UCI (i.e., HP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH, i.e., the MAC entity generates a MAC PDU for the first PUSCH and does not generate a MAC PDU for the second PUSCH.

As another example, assume that the priorities of the first PUSCH and the second PUSCH are both low priorities; at this time, as long as UCI is multiplexed on the first PUSCH, it may be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or MAC PDUs may be generated for the first uplink grant.

Fig. 7 is an example of an applicable scenario of a wireless communication method provided by an embodiment of the present application.

As shown in fig. 7, the terminal device is configured or scheduled to transmit a first PUSCH (i.e., low priority PUSCH (LP PUSCH)); wherein, the LP PUCCH to be transmitted and the first PUSCH overlap (overlap), i.e. the LP PUCCH is multiplexed to be transmitted on the first PUSCH; furthermore, the second PUSCH to be transmitted (i.e. low priority PUSCH (LP PUSCH)) overlaps with the first PUSCH, i.e. the priority of the first PUSCH is equal to the priority of the second PUSCH. At this time, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, the priority of the first uplink grant corresponding to the first PUSCH in which UCI (i.e., LP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH, i.e., the MAC entity generates a MAC PDU for the first PUSCH and does not generate a MAC PDU for the second PUSCH.

Example 2:

in this embodiment, if the priority of the first PUSCH is greater than the priority of the second PUSCH and UCI is multiplexed on the first PUSCH, whether UCI is multiplexed on the second PUSCH is transmitted or not is always determined to be higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant.

In other words, the priority of the first PUSCH is a high priority, and the priority of the second PUSCH is a low priority; at this time, as long as UCI is multiplexed on the first PUSCH, it may be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or MAC PDUs may be generated for the first uplink grant.

As shown in fig. 9, the terminal device is configured or scheduled to transmit a first PUSCH (i.e., high priority PUSCH (HP PUSCH)); wherein the HP PUCCH to be transmitted and the first PUSCH overlap (overlap), i.e. HP PUCCH multiplexing is transmitted on the first PUSCH; optionally, the first PUSCH has no data, that is, the MAC PDU corresponding to the first PUSCH has no data of multiplexing logical channels or no data of logical channels may be multiplexed in the MAC PDU corresponding to the first PUSCH; furthermore, the second PUSCH to be transmitted (i.e. low priority PUSCH (LP PUSCH)) overlaps with the first PUSCH, i.e. the priority of the first PUSCH is greater than the priority of the second PUSCH, and no UCI is multiplexed on the second PUSCH transmission; at this time, the priority of the first uplink grant corresponding to the first PUSCH to which UCI (i.e., HP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH, that is, the MAC entity generates a MAC PDU for the first PUSCH and does not generate a MAC PDU for the second PUSCH.

Example 2:

in this embodiment, if the priority of the first PUSCH is equal to the priority of the second PUSCH, UCI is multiplexed and transmitted on the first PUSCH, and no UCI is multiplexed and transmitted on the second PUSCH, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, it is always determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or a MAC PDU is generated for the first uplink grant.

As shown in fig. 10, the terminal device is configured or scheduled to transmit a first PUSCH (i.e., high priority PUSCH (HP PUSCH)); wherein the HP PUCCH to be transmitted and the first PUSCH overlap (overlap), i.e. HP PUCCH multiplexing is transmitted on the first PUSCH; optionally, the first PUSCH has no data, that is, the MAC PDU corresponding to the first PUSCH has no data of multiplexing logical channels or no data of logical channels may be multiplexed in the MAC PDU corresponding to the first PUSCH; furthermore, a second PUSCH (i.e., HP PUSCH) to be transmitted overlaps the first PUSCH, i.e., the priority of the first PUSCH is equal to the priority of the second PUSCH, and no UCI is multiplexed on the second PUSCH transmission; at this time, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, the priority of the first uplink grant corresponding to the first PUSCH to which UCI (i.e., HP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH to which UCI is not multiplexed, i.e., MAC entity generates MAC PDU for the first PUSCH and MAC PDU for the second PUSCH.

As an example, assume that the priorities of the first PUSCH and the second PUSCH are both low priorities; at this time, as long as UCI is multiplexed on the first PUSCH and no UCI is multiplexed on the second PUSCH, it may be determined that the priority of the first uplink grant is higher than the priority of the second uplink grant, or MAC PDU is generated for the first uplink grant.

At this time, regardless of the comparison result of the logical channel priority of the uplink grant corresponding to the first PUSCH and the logical channel priority of the uplink grant corresponding to the second PUSCH, the priority of the first uplink grant corresponding to the first PUSCH to which UCI (i.e., LP PUCCH) is multiplexed is always higher than the priority of the uplink grant corresponding to the second PUSCH to which UCI is not multiplexed, i.e., the MAC entity generates a MAC PDU for the first PUSCH and does not generate a MAC PDU for the second PUSCH.
