1. A user equipment (UE) configured for wireless communication, the UE comprising:
one or more power amplifiers (PAs);
at least one processor; and
a memory coupled to the at least one processor,
wherein the at least one processor is configured:
to transmit a capability message to a serving network entity, wherein the capability message includes an identification of a constrained radio frequency (RF) architecture of a beamforming network due to at least one PA of the one or more PAs of the UE when operating at millimeter wave (mmWave) frequencies, wherein the constrained RF architecture due to the at least one PA of the UE is associated with a phase shifting behavior or a gain control behavior or a combination thereof,
to communicate an indication of a communication performance loss of the beamforming network attributable to use, by the UE, of a subset of non-preferred phase shifting states from a plurality of available phase shifting states or a subset of non-preferred gain control states from a plurality of available gain control states or a combination of the subset of non-preferred phase shifting states and the subset of non-preferred gain control states; and
to perform a communication with the serving network entity at the mmWave frequencies according to at least one phase shifting state of the plurality of available phase shifting states or at least one gain control state of the plurality of available gain control states or at least a combination of the at least one phase shifting state and the at least one gain control state.
