Abstract

一种功率调整方法及装置，用于增加上行信号的发送功率的稳定性，使得上行信号能够有效的传输。该方法包括：接收MAC CE(201)，该MAC CE用于更新路损估计参考信号；根据路损估计参考信号确定路损估计值(202)；其中，该路损估计值的生效时间不晚于n+X+T，该n为发送反馈信息的时间，该反馈信息用于反馈该MAC CE是否被正确接收，该X为固定时长，该T为可变时长。从上可看出，该路损估计值的生效时间不晚于n+X+T，避免了无法在短时间内对路损估计参考信号的接收功率进行多次滤波，从而可使得通信装置可有足够的时间对该路损估计参考信号的接收功率进行多次滤波，路损估计值确定的稳定性和准确性。
