Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) indicating that the UE is to retransmit sidelink hybrid automatic repeat request (HARQ) feedback. The UE may retransmit the sidelink HARQ feedback on a physical uplink control channel for one or more sidelink HARQ processes based at least in part on the DCI. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive downlink control information (DCI) indicating that the UE is to retransmit sidelink hybrid automatic repeat request (HARQ) feedback;
- and
- retransmit the sidelink HARQ feedback on a physical uplink control channel (PUCCH) for one or more sidelink HARQ processes based at least in part on the DCI.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit downlink control information (DCI), to a user equipment (UE), indicating that the UE is to retransmit sidelink hybrid automatic repeat request (HARQ) feedback after the sidelink HARQ feedback is dropped;
- and
- receive the sidelink HARQ feedback on a physical uplink control channel (PUCCH) for one or more sidelink HARQ processes based at least in part on transmitting the DCI.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving downlink control information (DCI) indicating that the UE is to retransmit sidelink hybrid automatic repeat request (HARQ) feedback;
- and
- retransmitting the sidelink HARQ feedback on a physical uplink control channel (PUCCH) for one or more sidelink HARQ processes based at least in part on the DCI.
