Techniques for full-duplex operation on sidelink and downlink in wireless communications systems

Abstract

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a first user equipment (UE) to establish a communication link with a base station and a sidelink communication link with a second UE using different transmission reception points associated with the first UE. The first UE may perform an interference measurement between downlink communications received on the communication link and sidelink communications transmitted on the sidelink communication link. The first UE may determine whether it is able to perform full-duplex operations on the communication link and the sidelink communication link based on the interference measurement and may transmit an indication of the capability of the first UE to the base station. In some examples, the second UE may perform measurements of interference from downlink signals on the sidelink communication link, where the measurements may inform the determination to use full-duplex communications at the first UE.
