Abstract

In one embodiment of method and appartus for determining loading in a communication system, the communication system accumulates a power control commands series and corresponding transmit gain adjustments series between a base station and a designated remote station, under regular operating conditions. After transmissions form the remaining remote stations are interrupted, the communication system repeats the accumulation, and determines the loading according to the accumulated series. Alternatively, the communication system measures power of a test signal injected into base station receiver, under regular operating conditions. After transmissions form the remote stations are interrupted, the communication system repeats the measurement, and determines the loading according to the two measurements. Alternatively, the communication system measures gain of an AGC at the base station's receiver, under regular operating conditions. After transmissions form the remote stations are interrupted, the communication system repeats the measurement, and determines the loading according to the two measurements.
