Abstract

一种功率控制方法及装置，可以提高多传输接收点协同传输场景下终端设备确定发送功率的准确性。该方法应用于具有支持被配置多个控制资源集合组索引的能力和/或被配置多个控制资源集合组索引的终端中。该方法包括：接收网络设备发送的第一物理下行控制信道(S501)，第一物理下行控制信道携带物理下行控制信道对应的功率偏移量。根据网络设备对应的功控进程确定发送功率(S502)，功控进程用于对该网络设备指示的功率偏移量进行累加，并根据累加结果确定物理下行控制信道的发送功率。使用发送功率向网络设备发送物理下行控制信道(S503)。通过对来自同一个网络设备的功率偏移量进行独立累加，从而可以使得PUSCH的发送功率和网络设备的指示一致。
