PROCÉDÉ ET APPAREIL PERMETTANT DE DÉCLENCHER UN RAPPORT DE MARGE D'ALIMENTATION DE PUISSANCE POUR UN FONCTIONNEMENT DE FAISCEAU DANS UN SYSTÈME DE COMMUNICATION SANS FIL

摘要

Methods and apparatuses for triggering a power headroom report for beam operation in a wireless communication system are disclosed herein. In one method, a user equipment (UE) uses multiple beams for transmission (2805). The UE triggers a power headroom report due to a change of a pathloss being larger than a threshold, wherein the pathloss is associated with a specific beam or a set of beams (2810).
