Abstract
(EN)
Provided in the present application are a method and apparatus for determining a transmission power. The method comprises: a terminal device determining a first code rate of a first part of channel state information CSI-1, the first code rate being the number of bits of the CSI-1 carried on each resource unit on which the CSI-1 is transmitted; and the terminal device adjusting transmission power of a physical uplink shared channel (PUSCH) according to the first code rate, the PUSCH being used for carrying the CSI-1. According to the embodiments of the present application, the terminal device determines the transmission power of the PUSCH according to the first code rate, the first code rate being the number of bits of the CSI-1 carried on each resource unit on which the CSI-1 is transmitted, so as to facilitate improving the accuracy of the terminal device determining the transmission power of the PUSCH.

La présente invention concerne un procédé et un appareil de détermination d'une puissance de transmission. Le procédé comprend les étapes au cours desquelles : un dispositif terminal détermine un premier taux de codage d'une première partie d'informations d'état de canal CSI-1, le premier taux de codage étant le nombre de bits des CSI-1 transportés sur chaque unité de ressource sur laquelle les CSI-1 sont transmises ; et le dispositif terminal ajuste une puissance de transmission d'un canal physique partagé de liaison montante (PUSCH) en fonction du premier taux de codage, le PUSCH servant à transporter les CSI-1. Selon les modes de réalisation de la présente invention, le dispositif terminal détermine la puissance de transmission du PUSCH en fonction du premier taux de codage, le premier taux de codage étant le nombre de bits des CSI-1 transportés sur chaque unité de ressource sur laquelle les CSI-1 sont transmises, de façon à faciliter l'amélioration de la précision du dispositif terminal qui détermine la puissance de transmission du PUSCH.
