Urllc physical uplink control channel (PUCCH) with repetitions
A user equipment (UE) is described. The UE includes a processor configured to determine a subslot structure for physical uplink control channel (PUCCH) repetition for ultra-reliable low-latency communication (URLLC) transmissions. The UE also includes transmitting circuitry configured to transmit the PUCCH repetition for the URLLC transmissions based on the subslot structure.
1. A user equipment (UE), comprising:
a processor configured to determine a subslot structure for physical uplink control channel (PUCCH) repetition; and
transmitting circuitry configured to transmit the PUCCH repetition based on the subslot structure,
wherein the PUCCH repetition is configured for time domain,
PUCCH repetition within a subslot is not supported and one subslot-based PUCCH transmission is transmitted in a subslot, and
the PUCCH repetition is performed by PUCCH transmission in multiple subslots.
2. The UE of claim 1 , wherein the PUCCH repetition is configured for format 0, format 2, format 1, format 3, or format 4.
3. The UE of claim 1 , wherein if a subslot-based PUCCH repetition is scheduled to collide with another PUCCH in a subslot, the processor is further configured to determine an uplink control information (UCI) priority, wherein a PUCCH carrying a first UCI with a higher priority is transmitted and the other PUCCH is dropped.
4. The UE of claim 1 , wherein if a subslot-based PUCCH repetition is scheduled to collide with another PUCCH in a subslot with a same uplink control information (UCI) priority, a PUCCH that starts earlier is transmitted and the other PUCCH is dropped.
5. A base station (gNB), comprising:
a processor configured to determine a subslot structure for physical uplink control channel (PUCCH) repetition; and
receiving circuitry configured to receive the PUCCH repetition based on the subslot structure,
wherein the PUCCH repetition is configured for time domain,
PUCCH repetition within a subslot is not supported and one subslot-based PUCCH transmission is transmitted in a subslot, and
the PUCCH repetition is performed by PUCCH transmission in multiple subslots.
6. The gNB of claim 5 , wherein the PUCCH repetition is configured for format 0, format 2, format 1, format 3, or format 4.
7. The gNB of claim 5 , wherein if a subslot-based PUCCH repetition is scheduled to collide with another PUCCH in a subslot, the processor is further configured to determine an uplink control information (UCI) priority, wherein a PUCCH carrying a first UCI with a higher priority is transmitted and the other PUCCH is dropped.
8. The gNB of claim 5 , wherein if a subslot-based PUCCH repetition is scheduled to collide with another PUCCH in a subslot with a same uplink control information (UCI) priority, a PUCCH that starts earlier is transmitted and the other PUCCH is dropped.
9. A method performed by a user equipment (UE), comprising:
determining a subslot structure for physical uplink control channel (PUCCH) repetition; and
transmitting the PUCCH repetition based on the subslot structure,
wherein the PUCCH repetition is configured for time domain,
PUCCH repetition within a subslot is not supported and one subslot-based PUCCH transmission is transmitted in a subslot, and
the PUCCH repetition is performed by PUCCH transmission in multiple subslots.
