Description

Wireless communication method, terminal device and network device

technical field

The embodiments of the present application relate to the communication field, and more specifically, to a wireless communication method, a terminal device, and a network device.

Background technique

The new air interface (New Radio, NR) does not support simultaneous transmission of two overlapping uplink channels, such as Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) and PUSCH, PUSCH and Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH). For two overlapping uplink channels, a conflict resolution mechanism needs to be used to ensure the reliability of data transmission. Normally, the terminal device can resolve conflicting resources based on the conflict resolution mechanism of logical channel priority (lch-basedPrioritization) or the conflict resolution mechanism based on uplink skipping (UL skipping), so as to ensure the normal transmission of data.

However, when the logical channel-based priority (lch-basedPrioritization) and uplink skipping (UL skipping) are configured at the same time, the following situation will occur. For an uplink grant (uplink grant), according to the logical channel-based priority, It is a low priority and does not need to generate a MAC PDU, but according to the uplink skip, it may be a high priority (that is, a MAC PDU needs to be generated). Obviously, the results of these two conflict resolution mechanisms are contradictory, and then resulting in data transmission failure. Therefore, the present application urgently needs to further improve the conflict resolution mechanism to improve the reliability of data transmission.

In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

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

Logical channel based priority:

For a MAC entity, if the logical channel-based priority (lch-basedPrioritization) is configured, the priority of an uplink grant (uplink grant) is based on the multiplexing in the MAC PDU (that is, the MAC PDU to be sent has been stored in the HARQ buffer) or data can be multiplexed (that is, the MAC PDU to be sent is not stored in the HARQ buffer) the highest priority in the priority of the logical channel is determined (For the MAC entity configured with lch-basedPrioritization, 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 transmit to PD.the MAC is to multiplexed(i.e. not stored in the HARQ buffer) in the MAC PDU). If an uplink grant has no multiplexed logical channel data in its MAC PDU or no logical channel data can be multiplexed in the MAC PDU, then this uplink grant has priority over any logical channel data that 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 are multiplexed or can be multiplexed in the MAC PDU).

Physical layer priority:

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

Uplink skipping (UL skipping):

For a MAC entity, when no logical channel-based priority (lch-basedPrioritization) is configured:

If the configured skip uplink dynamic transmission parameter (enhancedSkipUplinkTxDynamic) is true (true), and the uplink grant indicated to the hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) entity is the Cell Radio Network Temporary Identifier (Cell Radio Network Temporary Identifier) , C-RNTI) scrambled, if the first condition is satisfied, no MAC PDU is generated for the HARQ entity.

If the configured skip uplink configuration transmission parameter (enhancedSkipUplinkTxConfigured) is true (true), and the uplink grant indicated to the HARQ entity is the configured uplink grant, if the first condition is met, then the HARQ entity does not generate a MAC PDU.

As an example, the first condition is:

1. If no UCI is to be multiplexed on this PUSCH transmission according to TS 38.213; and

2. If there is no aperiodic Channel State Information (CSI) request on this PUSCH transmission; and

3. If this MAC PDU contains 0 MAC SDUs; and

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

It can be seen that if the skip uplink dynamic transmission parameter is configured as true or if the skip uplink configuration transmission parameter is configured as true, based on condition 1 in the first condition, if there is uplink control information (Uplink Control Information, UCI) Multiplexing is performed on the PUSCH corresponding to an uplink grant, and the priority of an uplink grant is high priority, that is, a MAC PDU needs to be generated for this uplink grant.

As shown in Figure 2, even if the MAC PDU corresponding to the DG/CG PUSCH has no multiplexed data, since there is UCI (that is, the Physical Uplink Control Channel (PUCCH)) multiplexed and transmitted on this DG/CG PUSCH, The MAC layer also needs to generate a MAC PDU for the physical layer to ensure that UCI can be multiplexed and transmitted on the DG/CG PUSCH to avoid blind detection of the 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). For two overlapping uplink channels, a conflict resolution mechanism needs to be used to ensure the reliability of data transmission. Under normal circumstances, the terminal device can resolve conflicting resources based on the conflict resolution mechanism based on the logical channel priority (lch-basedPrioritization) or the conflict resolution mechanism based on the uplink skipping (UL skipping) configuration, so as to ensure the normal transmission of data .

The conflict resolution mechanism provided by the present application will be described below in combination with the logical channel-based priority, physical layer priority and uplink skip described above.

For the conflict resolution mechanism based on the priority of logical channels, if two PUSCH resources corresponding to two uplink grants overlap, the conflict resolution mechanism can be implemented at the Media Access Control (MAC) layer, namely The MAC layer will only generate a MAC protocol data unit (Protocol Data Unit, PDU) to the physical layer; that is, a conflict resolution mechanism can be designed based on the priority of the logical channel. Specifically, if the logical channel-based priority (lch-basedPrioritization) is configured, the MAC entity regards the uplink grant with a low priority as a de-prioritized uplink grant, and the uplink grant with a high priority as a de-prioritized uplink grant. Uplink grant (prioritized uplink grant), that is, to ensure the transmission of high-priority channels first. If no logical channel-based priority (lch-basedPrioritization) is configured, the MAC layer will generate a MAC PDU corresponding to a dynamic grant (DG) instead of a MAC PDU corresponding to a configured grant (CG). That is, the transmission of the channel with limited guarantee and dynamic scheduling. If the uplink PUSCH and PUCCH resources overlap, the conflict resolution mechanism can be implemented at the physical layer; that is, the conflict resolution mechanism can be designed based on the physical layer priority. Specifically, when uplink channels of 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 limitedly guaranteed. When PUSCH and PUCCH have the same physical layer priority, PUCCH can be multiplexed on PUSCH for transmission.

In addition, the terminal can also resolve the conflict caused by the overlapping of PUSCH and PUCCH resources based on the conflict resolution mechanism configured by uplink skipping (UL skipping). Specifically, for a MAC entity, when logical channel-based priority (lch-basedPrioritization) is not configured, if the skip uplink dynamic transmission parameter is configured as true or if the skip uplink configuration transmission parameter is configured as true, based on Condition 1 in the first condition, if there is uplink control information (Uplink Control Information, UCI) multiplexed in the PUSCH corresponding to an uplink grant for transmission, the priority of an uplink grant is high priority, that is, it needs to Authorization to generate MAC PDUs. In other words, even if the MAC PDU corresponding to the PUSCH has no data to be multiplexed (that is, data to be sent), since there is UCI to be multiplexed and transmitted on this PUSCH, the MAC layer must generate a MAC PDU to the physical layer to ensure that UCI can be transmitted on the PUSCH. Transmission on PUSCH avoids blind detection of PUSCH and PUCCH by the base station.

It can be seen that when configuring logical channel-based priority (lch-basedPrioritization) and uplink skipping (UL skipping) configurations at the same time, the following situation will occur. For an uplink grant (uplink grant), according to the logical channel-based priority level, which is low priority and does not need to generate a MAC PDU, but according to the uplink skipping, it may be a high priority (that is, a MAC PDU needs to be generated). Obviously, the results of these two conflict resolution mechanisms are contradictory , resulting in data transmission failure.

As shown in Figure 3, according to the configured priority based on the logical channel, the priority of the uplink grant corresponding to PUSCH 1 is lower than that of the uplink grant corresponding to PUSCH 2, that is, the uplink grant corresponding to PUSCH 1 is a non-priority uplink grant , the MAC layer does not generate a MAC PDU for the uplink authorization corresponding to the PUSCH 1; and according to the configured uplink skipping, the PUCCH and PUSCH 1 overlap (overlap), and the PUCCH will be multiplexed (multiplexed) to the PUSCH 1 for transmission, then It is necessary to generate a MAC PDU for the uplink authorization corresponding to the PUSCH 1; obviously, based on the priority of the logical channel and the uplink skipping at the same time, there will be conflicting results when determining whether to generate a MAC PDU for the uplink authorization corresponding to the PUSCH 1.

It should be noted that when determining whether to generate a MAC PDU for the uplink authorization corresponding to the PUSCH 1 based on the priority of the logical channel and the uplink skip, there will be two contradictory results; if only the two results are simply Screening, or simply designing the priority of logical channels and the priority of uplink skipping, will result in too low compatibility for improving data transmission reliability and controlling power consumption of network devices.

For example, if the priority of the uplink skip is higher than the priority based on the logical channel, then the MAC entity will generate a MAC PDU for PUSCH 1 (even if the corresponding uplink grant has a lower priority), which will cause an orange The data of PUSCH 2 (corresponding to high logical channel priority) cannot be transmitted, which is contrary to the working principle of intra-UE prioritization, that is, it is contrary to the working principle of ensuring the transmission of high priority data/channels first ; If the priority based on the logical channel priority is higher than the priority of uplink skipping, then the MAC entity will generate a MAC PDU for the uplink authorization corresponding to PUSCH 2, then PUSCH 1 cannot be transmitted, and UCI is transmitted on PUCCH or discarded (drop ) UCI on the PUCCH, but from the perspective of the base station, if the UCI on the PUCCH is not determined to be transmitted on PUSCH 1, the network equipment needs to perform blind detection on both PUSCH 1 and PUCCH to determine the transmission resources of UCI, which will cause the base station The power consumption increases.

Based on this, the present application provides a wireless communication method, terminal equipment, and network equipment, which can further improve the conflict resolution mechanism, so that it can not only improve the reliability of data transmission, but also minimize the blind detection of network equipment, that is, minimize the Power consumption of network equipment.

FIG. 4 is a schematic flowchart of a wireless communication method 200 provided by an embodiment of the present application. The method 200 can be executed by a terminal device. For example, it may be a terminal device as shown in FIG. 1 . Certainly, the method 200 may also be executed by the MAC entity and/or the physical layer in the terminal device, which is not specifically limited in this application.

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

S210. Determine the priority of the first uplink grant or determine whether to generate a MAC PDU for the first uplink grant according to at least one of the following:

Whether the MAC PDU corresponding to the first uplink authorization has the data of the multiplexing logical channel, or whether the data of the logical channel can be multiplexed in the MAC PDU corresponding to the first uplink authorization;

Whether UCI is multiplexed and transmitted on the second PUSCH.

In other words, in the case where the time domain resources of the first PUSCH and the second PUSCH overlap or partially overlap, the MAC PDU corresponding to the first uplink grant may be based on the priority of the first PUSCH, the priority of the second PUSCH, and the Whether there is multiplexed logical channel data or whether there is logical channel data that can be multiplexed in the MAC PDU corresponding to the first uplink grant, whether there is UCI multiplexed for transmission on the first PUSCH, whether there is UCI multiplexed In at least one of the transmissions on the second PUSCH, determine the priority of the first uplink grant or determine whether to generate a MAC PDU for the first uplink grant: wherein the first PUSCH is the first uplink grant scheduled or associated.

In short, the terminal device can 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 priority of the physical layer, the priority based on the logical channel, and the uplink skip. For example, for different situations, determine the physical layer priority, the priority based on logical channels, and the optimal configuration in uplink skipping, and then determine the priority of the first uplink grant based on the optimal configuration or determine whether to target the first Uplink authorization generates a MAC PDU. In other words, for different situations, the execution order or priority of physical layer priority, logical channel-based priority, and uplink skipping are different.

In this embodiment, according to the priority of the first PUSCH, the priority of the second PUSCH, whether the MAC PDU corresponding to the first uplink grant has multiplexed logical channel data or whether there is logical channel data that can be multiplexed in the In the MAC PDU corresponding to the first uplink grant, whether there is at least one of the uplink control information UCI multiplexing transmitted on the first PUSCH, and whether there is UCI multiplexing transmitted on the second PUSCH, determine the first The priority of the uplink authorization or determining whether to generate a MAC PDU for the first uplink authorization; equivalently, rebuilding the judgment for determining the priority of the first uplink authorization or determining whether to generate a MAC PDU for the first uplink authorization factor, avoiding conflicting results when determining the priority of the first uplink grant or determining whether to generate a MAC PDU for the first uplink grant due to the priority and uplink skipping based on the logical channel at the same time, and then, can further Improve the conflict resolution mechanism and improve the reliability of data transmission.

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

In addition, whether there is UCI multiplexed for transmission on the first PUSCH can be understood as: whether there is PUCCH multiplexed for transmission on the first PUSCH or whether there is UCI to be multiplexed (ie to be multiplexed) on the first PUSCH Transmission on the PUSCH; similarly, whether there is UCI multiplexing for transmission on the second PUSCH can be understood as: whether there is PUCCH multiplexing for transmission on the second PUSCH or whether there is UCI to be multiplexed (ie to be multiplexed) transmitted on the second PUSCH. Optionally, the priority of multiplexing the PUCCH transmitted on the first PUSCH is equal to the priority of the first PUSCH; similarly, the priority of multiplexing the PUCCH transmitted on the second PUSCH is equal to the priority of the The priority of the second PUSCH. In addition, in this application, if it is determined that the priority of the first uplink grant is higher than that of the second uplink grant, or a MAC PDU is generated for the first uplink grant; that is, it is equivalent to determining that the first uplink grant The priority of the second uplink grant is lower than that of the first uplink grant, or no MAC PDU is generated for the second uplink grant.

In addition, whether the MAC PDU corresponding to the first uplink authorization has multiplexed logical channel data or whether there is logical channel data that can be multiplexed in the MAC PDU corresponding to the first uplink authorization may include: performing uplink hopping Before passing the check (check), whether the MAC PDU corresponding to the first uplink authorization has multiplexed logical channel data or whether there is logical channel data that can be multiplexed in the MAC PDU corresponding to the first uplink authorization; but this Applications are not limited to this.
