SYSTEM AND METHOD FOR UE PROCESSING TIME RELAXATION FOR MULTI-TRP TRANSMISSION

Abstract:

Systems, devices, and techniques for adjusting a user equipment (UE) processing time parameter in a wireless communication system that include transmission and reception points (TRPs) are described. A described technique performed by UE includes receiving a first physical downlink shared channel (PDSCH) from a first TRP corresponding to a first scheduling physical downlink control channel (PDCCH) and a second PDSCH from a second TRP corresponding to a second scheduling PDCCH. The technique further includes transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) message and a second HARQ-ACK message based on the first PDSCH and the second PDSCH in accordance with a first processing time parameter and a second processing time parameter, respectively. The first processing time parameter can be based on a PDSCH mapping type, a processing capability of the UE, and one or more timing characteristics of the first PDSCH and the second PDSCH.
