  • Publication number: 20240243823
    Abstract: The present disclosure relates generally to wireless communications, and more particularly, to techniques for self-interference measurement (SIM) at a user equipment (UE). An apparatus for wireless communications may determine downlink (DL) symbols for measuring a self-interference (SI) between an active uplink (UL) transmit (Tx) beam of the UE and an active downlink (DL) receive (Rx) beam of the UE. The active uplink (UL) transmit (Tx) beam may be based on an uplink (UL) subcarrier spacing (SCS), and the active downlink (DL) receive (Rx) beam may be based on a downlink (DL) subcarrier spacing (SCS). The apparatus may perform a self-interference measurement (SIM) between the active uplink (UL) transmit (Tx) beam and the active downlink (DL) receive (Rx) beam. The apparatus may output for transmission, to a network entity, a report of the at least one self-interference measurement (SIM).
