Closed-loop power control method for a code-division multiple-access cellular system
Methods and apparatuses for a closed-loop power control in a code-division multiple-access communication system wherein both received signal quality and communication channel quality are used to determine appropriate transmitter power, and transmission may be suspended when a channel quality metric, such as by short-term fading, degrades below a preset minimum threshold, or when a commanded transmitter power exceeds a preset maximum threshold, and wherein the transmitter power is controlled to mitigate fading effects so that received signal quality metric, such as by the average received signal power or by the average received SIR over a control cycle, approaches a preset desired level, and by momentarily suspending a remote terminal, overall system capacity and throughput may be enhanced.
