1. A method of wireless communication at a user equipment (UE), comprising:
measuring one or more synchronization signal block (SSB) beams from a network entity;
selecting a highest rated SSB beam from the one or more SSB beams based on one or more selection factors;
transmitting a beam report including an identification of the highest rated SSB beam to the network entity;
initiating a timer in response to transmitting the beam report;
determining whether a media access control (MAC) control element (CE) is received from the network entity before expiration of the timer; and
performing beam switching from a current SSB beam to the highest rated SSB beam based on a determination that the MAC CE is not received from the network entity before expiration of the timer.
