1. A method, comprising:
determining, at a user equipment, user equipment current operating conditions, wherein the user equipment current operating conditions comprise one or more of a temperature, an operating frequency, a required antenna impedance bandwidth, a power level, a modulation, a supply voltage, or a proximity mismatch;
identifying whether an antenna configuration for maintaining a correspondence between user equipment transmission and reception beams is stored by said user equipment for said user equipment current operating conditions;
performing, responsive to failing to identify the antenna configuration, a reference signal sweep procedure to identify the antenna configuration for maintaining the correspondence between the user equipment transmission and reception beams for said user equipment current operating conditions, wherein the antenna configuration for one or more of the user equipment current operating conditions is updated during the reference signal sweep procedure; and
applying, responsive to identifying the antenna configuration, said antenna configuration for maintaining the correspondence between the user equipment transmission and reception beams.
