Demodulation reference signal based self-interference measurement

A method of wireless communication performed by a base station, comprising:

• receiving, from a user equipment (UE) in a full duplex communication mode, via an uplink (UL) transmit (Tx) beam from a first panel of the UE a data transmission or a control transmission, wherein the data transmission or control transmission comprises a demodulation reference signal (DMRS);
• receiving, from the UE, a measurement report indicating a self-interference measurement (SIM) associated with the uplink (UL) transmit (Tx) beam from the first panel and a downlink (DL) receive (Rx) beam from a second panel of the UE, wherein the SIM is based at least in part on the DMRS of the data transmission or the control transmission;
• and
• communicating using a selected beam pair based at least in part on the measurement report.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more memories and the one or more processors configured to:
• transmit, in a full duplex communication mode, a data transmission or a control transmission to a base station using an uplink (UL) transmit (Tx) beam from a first panel of the UE, wherein the data transmission or control transmission comprises a demodulation reference signal (DMRS);
• perform, based at least part on the DMRS of the data transmission or the control transmission, a self-interference measurement (SIM) associated with the uplink (UL) transmit (Tx) beam from the first panel and a downlink (DL) receive (Rx) beam from a second panel of the UE;
• and
• transmit, to the base station, a measurement report indicating the SIM.
