Title
(EN) REPETITION OF A MESSAGE 3 COMMUNICATION OF A FOUR-STEP RANDOM ACCESS CHANNEL PROCEDURE
Abstract
(EN)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a number of repetitions of a message 3 (msg3) communication of a four-step random access channel (RACH) procedure that are to be transmitted to a base station. The UE may transmit, to the base station, the repetitions of the msg3 communication based at least in part on determining the number of the repetitions of the msg3 communication. Numerous other aspects are provided.
