Title (EN) METHOD FOR PERFORMING A RANDOM ACCESS PROCEDURE IN WIRELESS COMMUNICATION SYSTEM AND A DEVICE THEREFOR
(FR) PROCÉDÉ D’EXÉCUTION D'UNE PROCÉDURE D’ACCÈS ALÉATOIRE DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET DISPOSITIF ASSOCIÉ
Abstract:
(EN) The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a random access procedure in wireless communication system, the method comprising: transmitting a random access preamble (RAP) on a physical random access channel (PRACH) resource in a radio frame; calculating a random access-radio network temporary identifier (RA-RNTI) by considering time-frequency resource associated with the PRACH resource and an index of a first radio frame of the PRACH resource; and monitoring a physical downlink control channel (PDCCH) identified by the calculated RA-RNTI for RAR reception during a RAR window.
(FR) La présente invention concerne un système de communication sans fil. Plus spécifiquement, la présente invention concerne un procédé et un dispositif d’exécution d'une procédure d’accès aléatoire dans un système de communication sans fil, le procédé comportant les étapes consistant à: émettre un préambule d’accès aléatoire (RAP) sur une ressource de canal physique à accès aléatoire (PRACH) dans une trame radio; calculer un identifiant temporaire de réseau radio à accès aléatoire (RA-RNTI) en considérant une ressource temps-fréquence associée à la ressource de PRACH et un index d'une première trame radio de la ressource de PRACH; et surveiller un canal physique de commande de liaison descendante (PDCCH) identifié par le RA-RNTI calculé pour déceler la réception de RAR pendant une fenêtre de RAR.
