MEASUREMENT GAP CONFIGURATION FOR MULTI-TRP ANTENNA CALIBRATION

Abstract:

A base station may perform online calibration of antenna elements at two or more transmission reception points (TRPs) based on measurements by one or more user equipment (UEs). The base station may transmit a request for the one or more UEs to perform antenna calibration measurements, for the two or more TRPs, during measurement gaps. The base station may coordinate, among the two or more TRPs, transmission of reference signals during the measurement gaps. The base station may receive a report based on the antenna calibration measurements from the one or more UEs. The base station may calibrate one or more antenna elements of the two or more TRPs based on the antenna calibration measurements.
