1. A method implemented in a network node, the method comprising:
determining a number of multiple-input multiple-output, MIMO, layers for a wireless device, WD, the determined number of MIMO layers being adjusted as compared to a maximum number of MIMO layers for the wireless device based at least in part on at least one parameter associated with at least one of the wireless device and the network node, the at least one parameter including at least one of pending downlink, DL, traffic to the wireless device, expected DL traffic to the wireless device, and historical traffic patterns;
determining a power savings gain for the wireless device resulting from the adjustment of the determined number of MIMO layers as compared to the maximum number of MIMO layers, the at least one parameter further including the power savings gain; and
signaling an indication of the determined number of MIMO layers to the wireless device.
