PROCÉDÉ ET DISPOSITIF DE TRAITEMENT DE RAPPORT D'ÉTAT DE MÉMOIRE TAMPON SUR LA BASE D'UNE REQUÊTE DE RÉSEAU DANS UN SYSTÈME DE COMMUNICATION MOBILE DE NOUVELLE GÉNÉRATION

摘要

According to the present invention, a method by which a terminal transmits a buffer status report (BSR) in a wireless communication system comprises the steps of: receiving, from a base station, a message including information for a BSR request; triggering the BSR on the basis of the information; and transmitting the BSR to the base station. The triggered BSR is a periodic BSR, and the triggering step causes a timer for the periodic BSR to expire. The information for a BSR request is indicated by a polling field included in a medium access control (MAC) sub-head.
