1. A wireless device, comprising:
at least one antenna array, wherein each of the at least one antenna array comprises a plurality of antenna elements;
at least one radio coupled to the at least one antenna element; and
one or more processors coupled to the at least one radio;
wherein the wireless device is configured to:
perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements of one or more antenna arrays of the at least one antenna array;
generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling; and
send the PHR report to a base station in communication with the wireless device.
