Description

Uplink transmission method, device and processor readable storage medium

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to an uplink transmission method, an uplink transmission device, and a processor readable storage medium.

Background

In the fifth generation New Radio (NR) system, simultaneous transmission of a plurality of PUCCHs (Physical Uplink Control Channel, physical Uplink control channels) or PUCCHs and PUSCHs (Physical Uplink SHARED CHANNEL) is not supported, and therefore, when the Uplink channels overlap in the time domain, multiplexing transmission or priority-based selection transmission is required.

On the one hand, when there is a PUCCH carrying CSI (CHANNEL STATE Information) or SR (Scheduling Request) in one slot and a PUCCH carrying HARQ-ACK-1 (Hybrid Automatic Repeat request-Acknowledgement-1, hybrid automatic repeat request Acknowledgement 1) collide, the PUCCH carrying HARQ-ACK-1 is overwritten by the PUCCH carrying HARQ-ACK-2; the multiplexed channel is the channel after the overlapping, i.e., the PUCCH carrying HARQ-ACK-2, as understood by Rel-15; therefore, the actual result is that the PUCCH carrying CSI or SR and the PUCCH carrying HARQ-ACK-2 are TDM (Time-division multiplexing, time division multiplexed) transmitted, but the PUCCH carrying HARQ-ACK-2 may be transmitted later in correspondence to the DCI (Downlink Control Information ), and the UE (User Equipment) does not know the existence of HARQ-ACK2 yet when preparing the transmission of CSI or SR, thereby affecting the transmission of CSI or SR. On the other hand, when there are multiple time division multiplexed PUSCHs in one slot that collide with one PUCCH, UCI in which a later PUSCH carries the PUCCH needs to be selected based on UCI (Uplink Control Information ) multiplexing rules, but DCI corresponding to the later PUSCH may be transmitted later, thereby affecting PUSCH transmitted earlier. For the collision of the part of uplink channels, the situation that the base station and the UE understand the inconsistency may occur, so that the transmission performance of the uplink channels is affected.

The character "/" generally indicates that the context-dependent object is an "or" relationship. The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

In order to better understand and illustrate aspects of embodiments of the present disclosure, some technical terms related to the embodiments of the present disclosure are briefly described below.

Currently, in an NR communication system, for the same UE, in order to avoid an excessive peak-to-average power ratio (Peak to Average Power Ratio, PARR), simultaneous transmission of PUCCH and PUSCH is not supported, so when time domain resources between PUCCH and PUSCH overlap, the UE may perform multiplexing transmission or select transmission based on channel priority.

Multiplexing transmission process: when multiple PUCCHs of the same physical layer priority or time domain resources of the PUCCH and PUSCH overlap, the UE may multiplex UCI carried by multiple PUCCHs on one PUCCH for transmission, or may multiplex UCI carried by the PUCCH on PUSCH for transmission.

PUCCH overlapping (overwriting/covering) transmission procedure: for multiple PDSCH transmissions indicating HARQ-ACK feedback to the same slot/sub-slot, PUCCH resources for HARQ-ACK feedback use are selected based on the PRI (PRIMARY RATE INTERFACE, base group rate interface) indicated by the DCI corresponding to the last PDSCH.

Selecting a transmission procedure based on channel priority: when the time domain resources of PUCCH and PUSCH with different physical layer priorities overlap, the UE only selects the channel with higher physical layer priority for transmission, and discards the channel with lower physical layer priority.

When the uplink channels collide, in order to avoid the influence of discarding the uplink control information on the system performance, the uplink control information is supported to be transferred to another uplink control channel or an uplink shared channel for transmission. For uplink channel collisions, a multiplexing timeline requirement is defined, which specifically includes the following two conditions:

The first OFDM (Orthogonal Frequency Division Multiplexing ) symbol of the earliest PUCCH/PUSCH in time in the conflicting channels is not earlier than the T1 time after the last symbol of any corresponding PDSCH transmission;

The first OFDM symbol of the earliest PUCCH/PUSCH in time in the conflict channel is not earlier than the T2 time after the last symbol of the PDCCH for scheduling uplink transmission;

The specific values of T1 and T2 are related to the relevant parameters of the collision channel and the specific situation of the collision channel.

When the PUCCH and the PUCCH/PUSCH collide, the UE can transmit all UCIs on one PUCCH or PUSCH only when the requirement of the time line is met, otherwise, the UCIs are considered as error conditions, and no regulation is made on the error conditions in the standard. That is, the base station needs to avoid occurrence of an error at the time of scheduling.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application.

In the embodiment of the application, aiming at the uplink channel conflict, the consistency of understanding of the user equipment UE and the base station for uplink transmission is ensured, and the transmission performance of the uplink channel is improved.

The embodiment of the application provides an uplink transmission method, which is executed by a network node, wherein a flow diagram of the method is shown in fig. 3, and the method comprises the following steps:

step S201, when any one of the channel rewritten by the first channel, the channel overlapped with the first channel and the second channel overlap, it is determined that a preset timeline requirement is satisfied between the first channel and the second channel at the time of scheduling, or the first channel and the second channel are overlapped.

In one embodiment, the base station needs to meet the corresponding timeline requirements at the time of scheduling, or ensure that no overlap situations occur that are not expected by the UE at the time of scheduling.

The uplink transmission method according to the above embodiment of the present application is described in full detail by the following embodiments:

in one embodiment of the application:

As shown in fig. 4, PUCCH and PUCCH carrying HARQ-ACK-1 collide, and SR or CSI is carried on PUCCH. When the resource carrying HARQ-ACK-2 needs to be indicated in the Slot (Slot) n, the resource carrying HARQ-ACK-2 will overwrite the resource carrying HARQ-ACK-1, and the DCI end time and PUCCH start time corresponding to HARQ-ACK-2 need to meet the timeline requirement.

Mode one of meeting timeline requirements:

When the base station schedules, the DCI end time and the PUCCH start time corresponding to the HARQ-ACK-2 are not less than T2, specifically, when the DCI end time and the PUCCH start time of the DCI carrying the HARQ-ACK-2 are greater than or equal to T2, the base station can indicate the resource carrying the HARQ-ACK-2 in a time slot n, otherwise, when the DCI and the PUCCH start time of the HARQ-ACK-2 are less than T2, the base station cannot indicate the resource carrying the HARQ-ACK-2 in the time slot n. The base station may select the resource that indicates the bearer HARQ-ACK-2 in the next slot.

When the UE receives DCI corresponding to the HARQ-ACK-2, the ending time of the PDCCH bearing the DCI of the HARQ-ACK-2 and the starting time of the PUCCH are always more than or equal to T2, otherwise, the UE can determine the situation of error.

In this embodiment, assuming that SCS (Sub-CARRIER SPACE, subcarrier spacing) used by the carrier where the PUCCH is located is configured to be 15kHz and the first UE uplink processing capability is used, the calculation formula (1) of T2 is as follows:

T2=max ((N ₂+d_2,1)(2048+144)·κ2^-μ·T_C,d_2,2) ≡ 784.9us formula (1)

And a second mode of meeting the requirement of the time line:

When the base station schedules, the time line requirements of multiplexing are met among the HARQ-ACK-2, the HARQ-ACK-1 and the PUCCH, namely, the time line requirements between the PDSCH end time and the PUCCH start time corresponding to the HARQ-ACK-2, the HARQ-ACK-1 are not smaller than The PDCCH end time and the PUCCH start time corresponding to the HARQ-ACK-2 and the HARQ-ACK-1 are not less than/>

When the UE receives the PDCCHs and PDSCH corresponding to the HARQ-ACK-2 and the HARQ-ACK-1, the time line requirement of multiplexing is always met between the PDCCHs, otherwise, the UE determines the situation of error.

In another embodiment of the application:

As shown in fig. 5, PUCCH and HARQ-ACK-1 collide, and SR or CSI is carried on PUCCH. When the resource of the bearing HARQ-ACK-2 needs to be indicated in the time slot n, the resource of the bearing HARQ-ACK-2 can overlap the resource of the bearing HARQ-ACK-1, and the base station needs to ensure that the resource of the bearing HARQ-ACK-2 and the resource of the PUCCH overlap when in scheduling. The UE does not expect the resource carrying HARQ-ACK-2 to overlap the resource carrying HARQ-ACK-1 and the resource carrying HARQ-ACK-1 overlaps with the PUCCH and the resource carrying HARQ-ACK-2 does not overlap with the PUCCH.

In another embodiment of the application:

As shown in fig. 6, the PUCCH is overlapped with the CG PUSCH and the DG PUSCH in the time domain at the same time slot, the CG PUSCH and the DG PUSCH are not overlapped in the time domain, and the PUCCH carries HARQ-ACK and/or CSI, so that UCI carried by the PUCCH is multiplexed (multiplexed) on the DG PUSCH resource, and the DCI end time and the CG PUSCH start time corresponding to the DG PUSCH need to meet the time line requirement.

Mode one of meeting timeline requirements:

When the base station schedules, the DCI end time and the CG PUSCH start time corresponding to the DGPUSCH are not less than T2, specifically, when the end time of the PDCCH carrying the DCI of the DGPUSCH and the CG PUSCH start time are greater than or equal to T2, the base station can schedule the resources of the DGPUSCH and the PUCCH in the time slot n to overlap in the time domain, otherwise, when the end time of the PDCCH carrying the DCI of the DGPUSCH and the CG PUSCH start time are less than T2, the base station cannot schedule the resources of the DGPUSCH and the PUCCH in the time slot n to overlap in the time domain. The base station may schedule DG PUSCH not to overlap PUCCH or select resources to schedule DG PUSCH in the next slot.

When the UE receives DCI corresponding to the DGPUSCH, the DCI of the DGPUSCH and the starting time of the CG PUSCH are always determined to be more than or equal to T2, otherwise, the UE determines that the situation is wrong.

In this embodiment, assuming that SCS configuration used by carriers where DG PUSCH, CG PUSCH and UCI are located is 15kHz at minimum, all use the first uplink processing capability, the calculation formula (1) of T2 is as follows:

T2=max ((N ₂+d_2,1)(2048+144)·κ2^-μ·T_C,d_2,2) ≡ 784.9us formula (1)

And a second mode of meeting the requirement of the time line:

When the base station schedules, the time line requirements of multiplexing are met among DGPUSCH, CG PUSCH and PUCCH, namely, the time line requirements between the PDSCH end time corresponding to the PUCCH and the CG PUSCH start time are not less than The PDCCH end time and the CG PUSCH start time corresponding to DG PUSCH, CG PUSCH and PUCCH are not less than/>

When the UE receives the DGPUSCH, the PDCCH corresponding to the PUCCH and the PDSCH, the time line requirement of multiplexing is always met between the UE and the CG PUSCH, otherwise, the UE can determine the error condition.

In another embodiment of the application:

as shown in fig. 7, PUCCH and CG PUSCH collide, and HARQ-ACK or CSI is carried on PUCCH. When DG PUSCH resources need to be indicated in a time slot n and overlap with PUCCH in the time domain, UCI carried on PUCCH is multiplexed on DG PUSCH, and when a base station needs to ensure that DG PUSCH resources and CG PUSCH resources overlap during scheduling. The UE does not expect the overlapping of DG PUSCH resources and PUCCH resources, and CG PUSCH and PUCCH overlap, and DG PUSCH resources do not overlap CG PUSCH.

In another embodiment of the application:

As shown in fig. 8, the PUCCH is overlapped with the PUSCH and another DG PUSCH carrying a-CSI in the time domain, where the PUSCH and another PUSCH carrying a-CSI are not overlapped in the time domain, and the PUSCH and another PUSCH carrying a-CSI may be in the same time slot or different time slots, where the PUCCH carries HARQ-ACK and/or CSI, and UCI carried by the PUCCH may be multiplexed on DG PUSCH resources carrying a-CSI, where the DCI end time and PUSCH start time corresponding to the DG PUSCH carrying a-CSI need to satisfy the timeline requirement.

Mode one of meeting timeline requirements:

When the base station schedules, it is ensured that the DCI end time corresponding to the DG PUSCH carrying the a-CSI and the PUSCH start time are not less than T2, specifically, when the DCI end time of the DCI PDCCH carrying the DG PUSCH of the a-CSI and the PUSCH start time are greater than or equal to T2, the base station may schedule the DG PUSCH resource carrying the a-CSI and the PUCCH to overlap in the time domain in the time slot n, whereas when the DCI end time of the PDCCH carrying the DG PUSCH of the a-CSI and the PUSCH start time are less than T2, the base station may not schedule the DG PUSCH resource carrying the a-CSI and the PUCCH to overlap in the time domain in the time slot n. The base station may schedule DG PUSCH carrying a-CSI not to overlap PUCCH or select resources to schedule DG PUSCH carrying a-CSI in the next slot.

When the UE receives DCI corresponding to the DGPUSCH carrying the A-CSI, the DCI of the DGPUSCH carrying the A-CSI and the starting time of the PUSCH are always determined to be more than or equal to T2, otherwise, the UE determines that the situation is wrong.

In this embodiment, assuming that SCS configuration used by the carrier where DG PUSCH, PUSCH and UCI carrying a-CSI are located is 15kHz at minimum, all use the first uplink processing capability, the calculation formula (1) of T2 is as follows:

T2=max ((N ₂+d_2,1)(2048+144)·κ2^-μ·T_C,d_2,2) ≡ 784.9us formula (1)

And a second mode of meeting the requirement of the time line:

When the base station schedules, the time line requirements of multiplexing are met among DGPUSCH, PUSCH and PUCCH carrying A-CSI, namely, the time line requirements between the PDSCH end time and the PUSCH start time corresponding to the PUCCH are not less than The time between the PDCCH end time and the PUSCH start time corresponding to the DGPUSCH, the PUSCH and the PUCCH carrying the A-CSI is not less than/>

When the UE receives the DGPUSCH carrying the A-CSI, the PDCCH and the PDSCH corresponding to the PUSCH and the PUCCH, the time line requirement of multiplexing is always met between the UE and the PUSCH, otherwise, the UE can determine the situation of error.

In another embodiment of the application:

As shown in fig. 9, PUCCH and one PUSCH collide, and HARQ-ACK or CSI is carried on PUCCH. When another DG PUSCH resource carrying a-CSI needs to be indicated in time slot n and overlaps with PUCCH in time domain, UCI carried on PUCCH is multiplexed on DG PUSCH carrying a-CSI, and when the base station is scheduled, it needs to ensure that the DG PUSCH resource carrying a-CSI overlaps with PUSCH resource. The UE does not expect the overlapping of the resources of DG PUSCH carrying a-CSI and the resources of PUCCH, and the overlapping of PUSCH and PUCCH and the overlapping of the resources of DG PUSCH carrying a-CSI and PUSCH.

In another embodiment of the application:

as shown in fig. 10, the CG PUSCH overlaps with the PUCCH and another DG PUSCH in the time domain at the same time, the PUCCH and DG PUSCH do not overlap in the time domain, the CG PUSCH and DG PUSCH are on the same carrier, and the PUCCH and CG PUSCH and DG PUSCH are on the same or different carriers. And if the PUCCH carries HARQ-ACK and/or CSI, the UCI carried by the PUCCH is multiplexed on CG PUSCH resources, and the DCI end time and the DGPUSCH start time corresponding to the PUCCH are required to meet the time line requirement.

In this embodiment, when CG PUSCH and DG PUSCH are interchanged, UCI carried by PUCCH is multiplexed on DG PUSCH, and a time line requirement is satisfied between a PDCCH end position requirement corresponding to PUCCH and a CG PUSCH start position.

In yet another embodiment of the present application:

As shown in fig. 11, the PUSCH overlaps with the PUCCH carrying the SR and the other PUCCH carrying the HARQ-ACK or CSI in the time domain, the PUCCH carrying the SR and the other PUCCH carrying the HARQ-ACK or CSI do not overlap in the time domain, the PUCCH carrying the SR and the other PUCCH carrying the HARQ-ACK or CSI are on the same carrier, and the PUSCH and the two PUCCH channels are on the same or different carriers. The UCI carried by the PUCCH is multiplexed on the PUSCH resource, and the DCI end time corresponding to the PUCCH and the PUCCH start time of the SR need to satisfy the timeline requirement.
