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: A MULTIPLE ACCESS, SPREAD-SPECTRUM COMMUNICATION SYSTEM PROCESSES A PLURALITY OF INFORMATION SIGNALS RECEIVED BY A RADIO CARRIER STATION (RCS) (104) OVER TELECOMMUNICATION LINES FOR SIMULTANEOUS TRANSMISSION OVER A RADIO FREQUENCY (RF) CHANNEL AS A CODE-DIVISION- MULTIPLEXED (CDM) SIGNAL TO A GROUP OF SUBSCRIBER UNITS (SUS). THE RCS (104) RECEIVES A CALL REQUEST SIGNAL THAT CORRESPONDS TO A TELECOMMUNICATION LINE INFORMATION SIGNAL, AND A USER IDENTIFICATION SIGNAL THAT IDENTIFIES A USER TO WHICH THE CALL REQUEST AND INFORMATION SIGNAL ARE ADDRESSED. THE RCS (104) INCLUDES A PLURALITY OF CODE DIVISION MULTIPLE ACCESS (CDMA) MODEMS, ONE OF WHICH PROVIDES A GLOBAL PILOT CODE SIGNAL, AND THE MODEMS PROVIDE A PLURALITY OF MESSAGE CODE SIGNALS SYNCHRONIZED TO THE GLOBAL PILOT SIGNAL. IN RESPONSE TO A CHANNEL ASSIGNMENT SIGNAL, EACH MODEM COMBINES AN INFORMATION SIGNAL WITH A MESSAGE CODE SIGNAL TO PROVIDE A CDM PROCESSED SIGNAL. THE RCS (104) INCLUDES A SYSTEM CHANNEL CONTROLLER COUPLED TO RECEIVE A REMOTE CALL. THE RCS (104), WHICH PROVIDES THE CHANNEL ASSIGNMENT SIGNAL RESPONSIVE TO THE USER IDENTIFICATION SIGNAL.AN RF TRANSMITTER IS CONNECTED TO ALL OF THE MODEMS TO COMBINE THE CDM PROCESSED SIGNALS WITH THE GLOBAL PILOT CODE SIGNAL TO GENERATE A CDM SIGNAL. THE RF TRANSMITTER ALSO MODULATES A CARRIER SIGNAL WITH THE CDM SIGNAL AND TRANSMITS THE MODULATED CARRIER SIGNAL THROUGH AN RF COMMUNICATION CHANNEL TO THE SUS. EACH SU CORRESPONDING TO THE USER IDENTIFICATION SIGNAL INCLUDES A CDMA MODEM, WHICH IS ALSO SYNCHRONIZED TO THE GLOBAL PILOT SIGNAL. THE CDMA MODEM DESPREADS THE CDM SIGNAL TO RECOVER THE INFORMATION' SIGNAL, AND PROVIDES THE INFORMATION SIGNAL TO THE USER. THE SYSTEM INCLUDES A CLOSED LOOP POWER CONTROL METHOD FOR MAINTAINING A MINIMUM SYSTEM TRANSMIT POWER LEVEL FOR THE RCS (104) AND THE SUS, AND SYSTEM CAPACITY MANAGEMENT FOR MAINTAINING A MAXIMUM NUMBER OF ACTIVE SUS FOR IMPROVED SYSTEM PERFORMANCE.(FIG 1)
