SUPPORTING NETWORK TRANSMISSIONS USING UNICAST SIDELINK COMMUNICATIONS

Abstract:

This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.
