Enhancements of high priority sr multiplexing on lp pusch

A base station (gNB), comprising:

• a processor and
• a memory storing instructions,
• wherein the instructions, when run by the processor, cause the UE to:
• in a case that a high priority (HP) physical uplink control channel (PUCCH) for more than 2 bits of HP hybrid automatic repeat request-acknowledgement (HARQ-ACK) with PUCCH format 2 or PUCCH format 3 or PUCCH format 4 overlaps with K PUCCHs for respective K HP scheduling requests (SRs) and a low priority (LP) physical uplink shared channel (PUSCH), and if HP HARQ-ACK multiplexing on the LP PUSCH is configured,
• if there is positive HP SR to be reported, receive a combination of HP HARQ-ACK bits and HP scheduling request (SR) bits multiplexed on the LP PUSCH as HP HARQ-ACK bits, wherein ┌log2(K+1)┐ bits for HP SR are appended to the HP HARQ-ACK, and
• if there is no positive HP SR to be reported, receive only HP HARQ-ACK bits multiplexed on the LP PUSCH.

A method performed by user equipment (UE), the method comprising:

• in a case that a high priority (HP) physical uplink control channel (PUCCH) for more than 2 bits of HP hybrid automatic repeat request-acknowledgement (HARQ-ACK) with PUCCH format 2 or PUCCH format 3 or PUCCH format 4 overlaps with K PUCCHs for respective K HP scheduling requests (SRs) and a low priority (LP) physical uplink shared channel (PUSCH), and if HP HARQ-ACK multiplexing on the LP PUSCH is configured,
• appending ┌log2(K+1)┐ bits for HP scheduling request (SR) to the HP HARQ-ACK;
• and
• if there is no positive HP SR to be reported, dropping the ┌log2(K+1)┐ bits and multiplexing only HP HARQ-ACK bits on the LP PUSCH.
