Title
(EN) METHOD FOR INDICATING POWER HEADROOM REPORT, AND APPARATUS
(FR) METHODE ET APPAREIL DONNANT LE COMPTE-RENDU DE RESERVE DE PUISSANCE, ET APPAREILLAGE
Abstract
(EN) Embodiments of the present invention disclose a method for determining a frequency resource, and an apparatus. The method includes: first determining, by user equipment (UE), a power headroom report; and subsequently sending, by the UE, the power headroom report (PHR) to a base station in a random access process, where the power headroom report may be carried by a related information segment of message 3 (Message 3) sent by the UE to the base station. According to the solutions provided in the present invention, a base station can obtain, in a timely manner, a basis for performing scheduling configuration when UE performs current uplink data transmission, and can more accurately configure power control and scheduling information for the UE. This avoids allocating the UE a channel that exceeds an uplink transmission capability of the UE, and thereby avoids an uplink bandwidth waste.
(FR) L'invention concerne un procédé et un dispositif pour indiquer un rapport de marge de sécurité de puissance (PHR). Le procédé comprend les étapes suivantes : un équipement utilisateur (UE) détermine premièrement un rapport de marge de sécurité de puissance; puis l'UE envoie le rapport de marge de sécurité de puissance (PHR) à une station de base dans un processus d'accès aléatoire, le rapport de marge de sécurité de puissance pouvant être porté par un segment d'informations associé d'un troisième message (message 3) envoyé par l'UE à la station de base. La solution fournie dans la présente invention peut permettre à une station de base d'acquérir de manière opportune une base pour réaliser une configuration de planification pour une transmission de données de liaison montante actuelle, de telle sorte que des informations de commande de puissance et de planification sont configurées de manière plus précise pour l'UE, évitant ainsi le gaspillage de bande passante de liaison montante provoqué par l'affectation à un UE d'un canal dépassant une capacité de transmission de liaison montante de l'UE.
