This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for a selection of a set of beams that a first cell or a second cell, or both, may use to communicate with a user equipment (UE) within a carrier-aggregation (CA) or dual-connectivity (DC) deployment. In one aspect, the UE may transmit an indication of the selected set of beams based on a mismatch between a default operating frequency (DOF) of antenna ports of each cell and antenna modules of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the first cell and the second cell and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select one or more ports that each cell may use to communicate with the UE based on the comparison.
