ALTERNATIVE TWO-STEP RACH PROCEDURE

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform an initial random access channel (RACH) attempt by transmitting, to a base station, an initial request message of an initial two-step RACH procedure; and perform an additional RACH attempt, using an alternative two-step RACH procedure, based at least in part on determining that an initial response message, corresponding to the initial request message, of the two-step RACH procedure is not received during an initial random access response window. Numerous other aspects are provided.
