Claim 13:
14. A method implemented in a wireless device (WD) the method comprising:
estimating an expected number of multiple-input multiple-output (MIMO) layers based at least in part on at least one of channel state information (CSI) or a sounding reference signal (SRS) configuration;
determining a set of antennas from among a plurality of antennas of the WD based on the estimated expected number of MIMO layers;
turning off antennas which are more than a maximum number of MIMO layers to save power consumption when a first quality metric is satisfied, and employing at least a same or a larger number than the maximum expected number of MIMO layers until a second quality metric is satisfied; and
receiving a MIMO signal using the determined set of antennas.
