1. A method of wireless communication by a user equipment (UE), comprising:
establishing a communication link with a device;
detecting at least one of: one or more obstructed antenna modules of a plurality of total antenna modules of the UE available for communication with the device; or one or more obstructed antenna subarrays of a plurality of total antenna subarrays of the UE available for communication with the device;
generating first information based at least on: a number of the plurality of total antenna modules or a number of the plurality of total subarrays, wherein the first information is a resulting number of antenna modules or antenna subarrays obtained by subtracting a number of the obstructed antenna modules from the number of the plurality of total antenna modules, or subtracting a number of the obstructed antenna subarrays from the number of the plurality of total antenna subarrays;
transmitting the first information associated with first beam configurations of the UE to the device;
receiving, from the device, second information associated with second beam configurations of the device; and
performing a beam training process by transmitting a number of reference signals to the device, wherein the number of the reference signals is derived from the first information associated with the first beam configurations and the second information associated with the second beam configurations.
