Title
(EN) METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR RÉALISER UNE COMMUNICATION DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
Methods and apparatuses for performing communication in a wireless communication system are provided. The method, performed by a user equipment (UE), of performing the communication in the wireless communication system, according to an embodiment, includes identifying an ongoing random access (RA) procedure triggered for a pending scheduling request (SR) transmission, identifying whether an active uplink bandwidth part (UL BWP) or an active downlink bandwidth part (DL BWP) is switched at an initiation of the ongoing RA procedure and performing an operation of switching the active UL BWP or the active DL BWP to an initiation BWP or an operation of terminating the ongoing RA procedure based on a result of the identification.

La présente invention concerne des procédés et des appareils pour réaliser une communication dans un système de communication sans fil. Le procédé, réalisé par un équipement d'utilisateur (UE), pour réaliser la communication dans le système de communication sans fil, comprend, selon un mode de réalisation, les étapes consistant à : identifier une procédure d'accès aléatoire (RA) en cours déclenchée pour une transmission en attente d'une demande de planification (SR); identifier si une partie de largeur de bande de liaison montante (UL BWP) active ou une partie de largeur de bande de liaison descendante (DL BWP) active a été commutée au lancement de la procédure RA en cours; et réaliser une opération pour commuter la UL BWP active ou la DL BWP active vers une BWP de lancement ou une opération pour mettre fin à la procédure RA en cours sur la base d'un résultat de l'identification.
