Abstract

A user equipment (UE) is described. The UE includes a processor configured to determine whether scheduling request (SR) reporting with hybrid automatic repeat request-acknowledgement (HARQ-ACK) with different priorities is supported. The processor is also configured to generate SR bits for multiplexing HARQ-ACK, wherein the HARQ-ACK having different priorities. The processor is further configured to multiplex the HARQ-ACK and the SR bits. The UE also includes transmitting circuitry configured to transmit the multiplexed HARQ-ACK and SR bits on a physical uplink control channel (PUCCH).

First claim

What is claimed is:

1 . A user equipment (UE), comprising:
a processor configured to:
for multiplexing of uplink control information (UCI) with different priorities, in a case that a first physical uplink control channel (PUCCH) transmission with high priority hybrid automatic repeat request-acknowledgement (HARQ-ACK) overlaps with a second PUCCH transmission with low priority HARQ-ACK, and in a case that the first PUCCH transmission overlaps with at least one transmission occasion for a high priority scheduling request (SR):
generate high priority SR bits for the high priority SR, at least one high priority HARQ-ACK bit, and at least one low priority HARQ-ACK bit, and
multiplex the at least one high priority HARQ-ACK bit, the high priority SR bits, and the at least one low priority HARQ-ACK bit on a PUCCH resource with PUCCH format 2, 3, or 4, configured for a high priority HARQ-ACK; and

transmitting circuitry configured to transmit the multiplexed at least one high priority HARQ-ACK bit, high priority SR bits, and at least one low priority HARQ-ACK bit on the PUCCH resource.

2 . The UE of claim 1 , wherein, the processor is further configured to:
generate the high priority SR bits based on a number of SR PUCCH configurations that overlap with the first PUCCH transmission; and append the high priority SR bits to the at least one high priority HARQ-ACK bits.

3 . The UE of claim 1 , wherein the high priority SR bits are included and low priority SR bits are not included when multiplexing with both the at least one high priority HARQ-ACK bit and the at least one low priority HARQ-ACK bit.

4 . A method performed by a user equipment (UE), the method comprising:
for multiplexing of uplink control information (UCI) with different priorities, in a case that a first physical uplink control channel (PUCCH) transmission with high priority hybrid automatic repeat request-acknowledgement (HARQ-ACK) overlaps with a second PUCCH transmission with low priority HARQ-ACK, and in a case that the first PUCCH transmission overlaps with at least one transmission occasion for a high priority scheduling request (SR):
generating high priority SR bits for the high priority SR, at least one high priority HARQ-ACK bit, and at least one low priority HARQ-ACK bit;
multiplexing the at least one high priority HARQ-ACK bit, the high priority SR bits, and the at least one low priority HARQ-ACK bit on a PUCCH resource with PUCCH format 2, 3, or 4, configured for a high priority HARQ-ACK; and
transmitting the multiplexed at least one high priority HARQ-ACK bit, high priority SR bits, and at least one low priority HARQ-ACK bit on the PUCCH resource.
