Spread spectrum transmitter power control method and system

In a remote station transceiver having a receiver for receiving a base station transmitted outbound spread spectrum signals wherein one of said outbound spread spectrum signals contains first user information and for demodulating said one outbound spread spectrum signal to provide said first user information to a first user, and a transmitter for transmitting to said base station an inbound spread spectrum signal containing second user information, said transceiver having a power control system for controlling at said transceiver the transmission signal power of said inbound spread spectrum signal wherein the signal power of said inbound spread spectrum signal as received at said base station is maintained about a predetermined average signal power level, and wherein said base station measures the signal power of said inbound spread spectrum signal as received at said base station, generates power adjustment commands according to variations in said measured signal power of said inbound spread spectrum signal with respect to said predetermined average signal power level and transmits said power adjustment commands in said one outbound spread spectrum signal, said power control system comprising:

• control processor means coupled to said receiver for receiving from said receiver said power adjustment commands in said one outbound spread spectrum signal, accumulating values corresponding to said power adjustment commands with respect to a predetermined first power level value, and generating a corresponding first power level control signal, said control processor means further for generating a power level set signal;
• automatic gain control means coupled to said receiver for measuring signal power of all of said outbound spread spectrum signals received by said receiver, and providing a corresponding power measurement signal;
• comparator means for receiving and comparing said power measurement signal and said power level set signal, and providing a corresponding second power level control signal;
• and
• amplification means coupled to said transmitter for receiving said first and second power level control signals and amplifying said inbound spread spectrum signal at a gain level determined by said first and second power level control signals.

A system for controlling the transmission power of a first remote transceiver of a plurality of remote transceivers, wherein each remote transceiver is for transmitting a spread spectrum communication signal to a base transceiver within a first predetermined frequency band, said base transceiver also transmitting a spread spectrum communication signal to at least said first remote transceiver within a second predetermined frequency band, said system comprising:

• first power control means for determining combined signal power of said base transceiver transmitted spread spectrum communication signal and other signals within said second predetermined frequency band as received at said first transceiver, detecting variations in said first power control means determined signal power with respect to a first predetermined transmit power level, and adjusting signal power of said first transceiver transmitted spread spectrum communication signal in response to said first power control means detected variations;
• and
• second power control means for determining signal power of said first transceiver transmitted spread spectrum communication signal as received at said second transceiver, detecting variations in said second power control means determined signal power with respect to a second predetermined transmit power level, adjusting signal power of said first transceiver transmitted spread spectrum communication signal in response to said second power control means detected variations.
