Uplink collision handling for multiple transmit-receive point operation
The present application relates to devices and components including apparatus, systems, and methods to provide collision resolution procedures in wireless communication systems.
1. One or more non-transitory, computer-readable media having instructions that, when executed, cause processing circuitry to:
identify a collision between first physical uplink channel transmission and a second physical uplink channel transmission, wherein the first physical uplink channel transmission is a physical uplink control channel (PUCCH) transmission without repetition and the second physical uplink channel transmission includes a plurality of physical uplink shared channel (PUSCH) repetitions;
determine a first target transmit receive point (TRP) for the first physical uplink channel transmission;
determine a second target TRP for the second physical uplink channel transmission;
perform a collision resolution procedure based on the first and second target TRPs, wherein to perform the collision resolution procedure the processing circuitry is to:
determine a relative priority between the PUCCH transmission and the plurality of PUSCH repetitions based on information corresponding to the first and second TRPs;
drop a first one of the PUCCH transmission or one or more repetitions of the plurality of PUSCH repetitions based on the relative priority; and
output for transmission a second one of the PUCCH transmission or the one or more repetitions of the plurality of PUSCH repetitions based on the relative priority.
2. The one or more non-transitory, computer-readable media of claim 1 , wherein the information corresponding to the first and second TRPs comprises a first TRP index associated with the first TRP and a second TRP index associated with the second TRP, wherein a higher relative priority is associated with a lower value of the first and second TRP indices.
3. The one or more non-transitory, computer-readable media of claim 2 , wherein the first and second TRP indices comprise first and second control resource set pool indices.
4. The one or more non-transitory, computer-readable media of claim 1 , wherein the plurality of PUSCH repetitions are in consecutive slots or in consecutive symbols.
5. A method comprising:
identifying a collision between a physical uplink control channel (PUCCH) transmission and a physical uplink shared channel (PUSCH) transmission, wherein the PUSCH transmission includes a plurality of PUSCH repetitions to be transmitted on at least two beams;
selecting, as a first PUSCH repetition, an earliest PUSCH repetition that is to be transmitted on a first beam that meets a timeline constraint associated with uplink control information (UCI);
selecting, as a second PUSCH repetition, an earliest PUSCH repetition that is to be transmitted on a second beam of the at least two beams that meets the timeline constraint associated with the UCI;
multiplexing UCI from the PUCCH transmission to the first PUSCH repetition and to the second PUSCH repetition; and
outputting the plurality of PUSCH repetitions for transmission.
6. The method of claim 5 , wherein the first PUSCH repetition is the earliest PUSCH repetition of the first beam that meets the timeline constraint and is actually to be transmitted; and the second PUSCH repetition is the earliest PUSCH repetition of the second beam that meets the time constraint and is actually to be transmitted.
7. The method of claim 5 , wherein the first beam and the second beam include different sounding reference signal resource indicators, transmission precoder matrix indicators, or power control parameters.
