Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to initiate a random access channel (RACH) procedure with a base station (BS). The UE may determine, based at least in part on determining to initiate the RACH procedure, whether a timing alignment timer, associated with a timing alignment of the UE and the BS, is expired. The UE may initiate the RACH procedure using the timing alignment based at least in part on determining that the timing alignment timer is not expired. Numerous other aspects are provided.
