Supporting network transmissions using broadcast sidelink communications

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the UE to:
• receive, from a base station (BS), a set of packets;
• receive, from the BS, an instruction to transmit a first sidelink communication comprising a first set of missed packets, wherein:
• the first set of missed packets are missed by another UE, and
• the first set of missed packets includes one or more decoded packets of a set of decoded packets;
• transmit, to the other UE, the first sidelink communication;
• and
• receive, from the other UE, a second sidelink communication comprising a second set of missed packets, wherein the second set of missed packets are missed by the UE.

An apparatus for wireless communication at a base station (BS), comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the BS to:
• transmit, to a plurality of user equipments (UEs), a set of packets;
• transmit, to a first UE, a first instruction to transmit a first sidelink communication comprising a first set of missed packets, the first set of missed packets having been missed by a second UE, the first set of missed packets including one or more decoded packets of a first set of decoded packets that are not included in a second set of decoded packets;
• and
• transmit, to the second UE, a second instruction to transmit a second sidelink communication comprising a second set of missed packets, the second set of missed packets having been missed by the first UE, the second set of missed packets including one or more decoded packets of the second set of decoded packets that are not included in the first set of decoded packets.
