Abstract: The invention provides a spread spectrum communication system for maintaining an initial transmit power level of a communication station during periods of inactivity. The system comprises a first station (501) and a second station (502), the initial transmit power level of which is maintained, wherein the first station generates an automatic power control signal by comparing a measured noise power level in a communication channel and an estimated system transmit power level and the second station occasionally transmits a spread spectrum signal whilst in an inactive state and receives the automatic power control signal to adjust an initial transmit power level thereof.

Abstract: An automatic power control (APC) system for a spread-spectrum communications system includes an automatic forward power control (AFPC) system, and an automatic reverse power control (ARPC) system. In the AFDC, each subscriber unit (SU) measures a forward signal-to-noise ratio of a respective forward channel information signal to generate a respective forward channel error signal which includes a measure of the uncorrelated noise in the channel and a measure of the error between the respective forward signal-to-noise ration and a pre determined signal-to-noise value. A control signal generated from the respective forward channel error signal is transmitted as part of a respective reverse channel information signal. A base unit includes AFPC receivers which receive respective reverse channel information signals and extract the forward channel error signals therefrom to adjust the power levels of the respective forward spread-spectrum signals. In the ARPC system, each base measures a reverse signal-to-noise ratio of each of the respective reverse channel information signals and generates a respective reverse channel error signal which includes a measure of the uncorrelated noise in the channel and a measure of the error between the respective reverse signal-to- noise ratio and a pre determined signal-to-noise value. The base unit transmits a control signal generated from the respective reverse channel error signal as a part of a respective forward channel information signal. Each SU includes an ARPC receiver which receives the forward channel information signal and extracts the respective reverse error signal to adjust the reverse transmit power level of the respective reverse spread-spectrum signal.

Abstract: An automatic power control (APC) system for a spread-spectrum communications system includes an automatic forward power control (AFPC) system, and an automatic reverse power control (ARPC) system. In the AFPC, each subscriber unit (SU) measures a forward signal-to-noise ratio of a respective forward channel information signal to generate a respective forward channel error signal which includes a measure of the uncorrelated noise in the channel and a measure of the error between the respective forward signal-to-noise ration and a pre determined signal-to-noise value. A control signal generated from the respective forward channel error signal is transmitted as part of a respective reverse channel information signal. A base unit includes AFPC receivers which receive respective reverse channel information signals and extract the forward channel error signals therefrom to adjust the power levels of the respective forward spread-spectrum signals. In the ARPC system, each base measures a reverse signal-to-noise ratio of each of the respective reverse channel information signals and generates a respective reverse channel error signal which includes a measure of the uncorrelated noise in the channel and a measure of the error between the respective reverse signal-to- noise ratio anda pre determined signal-to-noise value. The base unit transmits a control signal generated from the respective reverse channel error signal as a part of a respective forward channel information signal. Each SU includes an ARPC receiver which receives the forward channel information signal and extracts the respective reverse error signal to adjust the reverse transmit power level of the respective reverse spread-spectrum signal.
