Title
(EN) DETERMINING AN INITIAL PRACH PREAMBLE TRANSMISSION POWER BASED ON HISTORICAL COMPLETED PRACH PROCEDURES
(FR) DÉTERMINATION D'UNE PUISSANCE D'ÉMISSION INITIALE DE PRÉAMBULE DE CANAL PRACH SUR LA BASE DE PROCÉDURES HISTORIQUES TERMINÉES DE CANAL PRACH
Abstract
(EN) In an aspect, a UE may determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures. The UE may further attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.
(FR) Selon un aspect, un EU peut déterminer une puissance d'émission initiale pour la transmission d'un préambule de canal physique d'accès aléatoire (PRACH) d'une procédure de canal PRACH sur la base d'une puissance d'émission finale de préambule de canal PRACH associée à un ensemble de procédures historiques terminées de canal PRACH. L'EU peut en outre tenter une transmission initiale du préambule de canal PRACH sur la base de la puissance d'émission initiale déterminée.
