1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive a beam refinement configuration indicating beam measurement is restricted to a serving cell and excluded for a neighbor cell;
measure a synchronization signal block (SSB) of the serving cell by sweeping multiple beams restricted based on the beam refinement configuration, wherein measurement of a concurrent SSB of the neighbor cell is excluded in the sweeping of the multiple beams; and
identify a refined beam for the serving cell based on the sweeping of the multiple beams; and
wherein to sweep the multiple beams to measure the SSB of the serving cell, the at least one processor is further configured to:
monitor one or more symbols of the SSB of the serving cell using a respective wide beam from a plurality of wide beams of the UE;
identify a highest rated wide beam of the UE based on the monitoring the one or more symbols of the SSB of the serving cell using the respective wide beam from the plurality of wide beams of the UE; and
monitor one or more different symbols of the SSB of the serving cell using a respective narrow beam associated with the highest rated wide beam.
