Title:
HYBRID AUTOMATIC REPEAT REQUEST (HARQ) CODEBOOK ENHANCEMENT AND PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) RESOURCE DETERMINATION WITH SIDELINK FEEDBACK FORWARDING
Document Type and Number:
WIPO Patent Application WO/2021/077400
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.
