During the process of radio transmission of signals, to
reduce the interference, to increase the utilization efficiency of the
frequency spectrum, and to prolong the battery life, the transmission power can
be adjusted, that is called power control. More specifically, the power control
refers to adjust the transmission power of the mobile station or base station
in the radio mode within a certain range. Its objective is the same as that of
the DTX. When the receiving level and quality is rather strong, the transmission power at the TX terminal can
be reduced appropriately so that the communication can be kept at a certain
level. In this way, the interference on other calls around can be reduced. The
specific process will be described in the subsequent content together with Huawei power control
algorithm.
