Claim 0:
1. A wireless device (WD) configured to communicate with a network node of a communication system, the WD comprising:
a radio interface having a plurality of antennas; and
processing circuitry configured to:
estimate 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;
determine a set of antennas from among the plurality of antennas based on the estimated expected number of MIMO layers;
receive a MIMO signal using the determined set of antennas; and
turn off antennas which are more than a maximum number of MIMO layers to save power consumption when a first quality metric is satisfied, and to employ at least a same or a larger number than the maximum expected number of MIMO layers until a second quality metric is satisfied.
