Overhead reduction and reliability enhancements for dl control signaling

A user equipment (UE) comprising:

• a processor configured to determine:
• that a transmission of a first physical uplink control channel (PUCCH) would overlap in time with a transmission of a physical uplink shared channel (PUSCH), and
• a first priority for the first PUCCH and a second priority for the PUSCH;
• and
• a transceiver, operably coupled to the processor, the transceiver configured to transmit:
• only the PUSCH when the first priority is same as the second priority, wherein the PUSCH includes first uplink control information (UCI), and
• both the PUSCH and the first PUCCH when the first priority is different than the second priority, wherein the first PUCCH includes the first UCI.

A base station comprising:

• a processor configured to determine:
• that a reception of a first physical uplink control channel (PUCCH) would overlap in time with a reception of a physical uplink shared channel (PUSCH), and
• a first priority for the first PUCCH and a second priority for the PUSCH;
• and
• a transceiver, operably coupled to the processor, the transceiver configured to receive:
• only the PUSCH when the first priority is same as the second priority, wherein the PUSCH includes first uplink control information (UCI), and
• both the PUSCH and the first PUCCH when the first priority is different than the second priority, wherein the first PUCCH includes the first UCI.
