Title
(EN) REPETITION OF A MESSAGE 3 COMMUNICATION OF A FOUR-STEP RANDOM ACCESS CHANNEL PROCEDURE
(FR) RÉPÉTITION D'UNE COMMUNICATION DE MESSAGE 3 D'UNE PROCÉDURE DE CANAL D'ACCÈS ALÉATOIRE EN QUATRE ÉTAPES
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.
(FR) Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut déterminer un nombre de répétitions d'une communication de message 3 (msg3) d'une procédure de canal d'accès aléatoire (RACH) en quatre étapes qui doivent être transmises à une station de base. L'UE peut transmettre, à la station de base, les répétitions de la communication de msg3 sur la base, au moins en partie, de la détermination du nombre de répétitions de la communication de msg3. La divulgation concerne également de nombreux autres aspects.
