One method determines, in a first mode, a first value associated with a wireless link and a second values associated with the wireless link, the first value being indicative of a first metric and the second value being indicative of a second metric different from the first metric. The first value and the second value collectively indicate a category of channel quality for the wireless link. The method determines that the wireless device can operate in a second mode for subsequent data based on the category of channel quality, wherein in the second mode the wireless device consumes less power than in the first power mode. The method receives, in the second mode, second data over the wireless link.

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.
