1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive, using at least one wake up receiver (WUR) associated with the UE, one or more wake up signals for beam tracking (WUTs),
wherein the one or more WUTs are associated with a first on-off keying (OOK) signal having a first bit sequence that is different than a second bit sequence of a second OOK signal associated with a wake up signal (WUS);
measure a quality of each WUT, of the one or more WUTs; and
activate a main receiver associated with the UE to perform a beam recovery procedure based at least in part on a measured quality of at least one WUT, of the one or more WUTs.
