TRANSMIT POWER ADJUSTMENT FOR FULL DUPLEX FEEDBACK

Abstract:

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) operating according to full duplex (e.g., transmit and receive concurrently) may adapt a transmit power of a sidelink feedback message based on priorities of data messages. For example, the UE may determine a priority of a first data message received at the UE in a previous slot and a priority of a second data message transmitted to the UE in a previous slot. Based on a comparison of the priorities of the data messages, the UE may adjust a transmit power for a feedback message indicating a decoding outcome of the first data message and transmit the feedback message according to the adjusted transmit power while receiving a feedback message indicating the decoding outcome of the second data message thereby increasing efficiency while reducing interference.
