Superposition of sidelink and uplink transmissions

A method for wireless communications by a base station, comprising:

• transmitting, to a first user equipment (UE), control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE;
• receiving an indication that indicates superposition coding is being used or that indicates an intent to use superposition coding to generate a concurrent sidelink and uplink transmission;
• and
• receiving the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based at least in part on the indication.

An apparatus for wireless communications by a first user equipment (UE), comprising:

• a processor;
• a transceiver,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE;
• transmit, via the transceiver, an indication that indicates superposition coding is being used or that indicates an intent to use superposition coding to generate a concurrent sidelink and uplink transmission;
• and
• transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based at least in part on the indication.
