ABSTRACT:
A method and apparatus is provided for estimating signal power. This is accomplished by demodulating a received communication signal to derive a stream of samples. These samples may consist of either reference samples, data samples, or a combination thereof. An estimate of the power of the received communication signal is then generated as a function of the stream of samples. The signal power estimate may, for example, be used in a power control algorithm by setting a power control indicator in response to a comparison between the signal power estimate and a predetermined threshold. Subsequently, the power control indicator is transmitted over a communication channel to another communication unit. The communication unit detects a power control indicator within a signal received from over the communication channel and adjusts a particular signal transmission power of a signal transmitter in response to the detected power control indicator.
