1. A method of wireless communication of a user equipment (UE), comprising:
receiving a set of synchronization signal blocks (SSBs), each SSB of the set of SSBs transmitted on four symbols, wherein each SSB of the set of SSBs is transmitted on a respective beam;
determining a subset of SSBs of the set of SSBs for which less than the four symbols associated with the SSBs are to be used for measurement of the SSBs;
applying a zero-element beam (ZEB) to remaining symbols other than the less than the four symbols of each SSB in the subset of SSBs, wherein applying the ZEB reduces a receiving power on at least one receiver at the UE for a reception of the remaining symbols of each SSB in the subset of SSBs; and
when the less than the four symbols is greater than zero, measuring each SSB of the subset of SSBs through the less than the four symbols associated with the SSB.
