Retransmission in shared resource

A network entity, comprising:

• a processing system that includes one or more processors and one or more code-storing memories coupled with the one or more processors, the processing system configured to cause the network entity to:
• transmit an identifier (ID) for a user equipment (UE) and a resource pool configuration associated with a resource allocation for downlink control information (DCI) associated with a retransmission grant within a resource pool shared by the UE and one or more other UEs;
• receive a physical uplink shared channel (PUSCH) message based at least in part on the ID and the resource pool configuration;
• and
• transmit the DCI based at least in part on the resource allocation.

A user equipment (UE), comprising:

• a processing system that includes one or more processors and one or more code-storing memories coupled with the one or more processors, the processing system configured to cause the UE to:
• transmit a physical uplink shared channel (PUSCH) message in a first resource allocation within a resource pool shared by more than one UE, based at least in part on a resource pool configuration;
• monitor for feedback for the PUSCH message in a second resource allocation that is associated with the first resource allocation;
• and
• transmit a retransmission of the PUSCH message based at least in part on the feedback being a negative acknowledgment.
