Abstract

Systems and methods herein remedy thermal constraints experienced by wireless communication systems operating in the millimeter wave spectrum. User equipment (UE) having a plurality of antenna subarrays controlled by respective RFICs monitor temperature gradients of respective sectors of the UE. Upon the thermal gradient of a sector reaching a temperature threshold, the UE performs thermal management steps to prevent hardware of a respective sector from damage due to overshoot.
