一种功率余量上报的方法和设备
Abstract:
(EN)
The embodiments of the present invention relate to the technical field of wireless communications, and in particular, to a method, system and device for reporting power headroom, which are used to achieve the reporting of power headroom at the moment when the PRACH is concurrent with the PUSCH and/or PUCCH. The method provided in the embodiments of the present invention comprises: user equipment determining a power headroom value corresponding to each cell which transmits the physical uplink channel after determining that there is a need to concurrently transmit preamble and the physical uplink channel at the moment of reporting power headroom; and the user equipment reporting the determined power headroom value. Since power headroom can be reported at the moment when the PRACH is concurrent with the PUSCH and/or PUCCH, the power distribution conditions of the user equipment at the concurrent moment can be indicated to the network side to provide a basic assurance for the uplink power distribution on the network side, improving system performance.
(FR)
Selon des modes de réalisation, l'invention concerne le domaine technique des communications sans fil, et en particulier, un procédé, un système et un dispositif servant à rapporter une marge de puissance, qui sont utilisés pour obtenir le rapport d'une marge de puissance au moment où le PRACH est simultané avec le PUSCH et/ou le PUCCH. Le procédé décrit dans les modes de réalisation de la présente invention comprend les étapes suivantes : un équipement utilisateur détermine une valeur de marge de puissance correspondant à chaque cellule qui transmet le canal de liaison montante physique après avoir déterminé qu'il y a un besoin de transmettre simultanément le préambule et le canal de liaison montante physique au moment de rapporter une marge de puissance ; et l'équipement utilisateur rapporte la valeur de marge de puissance déterminée. Etant donné que la marge de puissance peut être rapportée au moment où le PRACH est simultané avec le PUSCH et/ou le PUCCH, les conditions de distribution de puissance de l'équipement utilisateur au moment simultané peuvent être indiquées au côté réseau pour fournir une assurance de base pour la distribution de puissance de liaison montante sur le côté réseau, ce qui améliore la performance du système.
(ZH)
本发明实施例涉及无线通信技术领域,特别涉及一种功率余量上报的方法、系统和设备,用以实现在PRACH与PUSCH和/或PUCCH并发时刻进行功率余量上报。本发明实施例提供的方法包括:用户设备在确定功率余量上报时刻存在preamble和物理上行信道需要并发传输后,确定每个传输物理上行信道的小区对应的功率余量值;所述用户设备上报确定的功率余量值。由于在PRACH与PUSCH和/或PUCCH并发时刻能够进行功率余量上报,从而能够指示给网络侧在并发时刻用户设备的功率分配情况,为网络侧分配上行功率提供基础保证,提高了系统性能。
