1. A method of wireless communication by a user equipment (UE), comprising:
determining a first synchronization signal block (SSB) to monitor for beam management, the first SSB comprising a primary synchronization signal (PSS), a plurality of physical broadcast channels (PBCHs), and a secondary synchronization signal (SSS);
determining a list of receive beams for measuring the first SSB; and
measuring the first SSB by:
measuring the PSS with a first beam from the list of receive beams;
measuring, with a second beam from the list of receive beams, a first demodulation reference signal (DMRS) on a first PBCH symbol of a first PBCH of the plurality of PBCHs;
measuring the SSS with a third beam from the list of receive beams; and
measuring, with a fourth beam from the list of receive beams, a second DMRS on a second PBCH symbol of a second PBCH of the plurality of PBCHs, in which the first beam, the second beam, the third beam and the fourth beam are each different beams.
