Abstract:
A method for power control in spread spectrum communication systems, the method comprising the steps of:providing two or more multiplexed registers coupled to a control circuit, the multiplexed registers controlled by a control signal derived from transmit power control (TPC) information, one register containing an increased power control value, the other register containing a decreased power control value; measuring a transmit power after an uplink transmit slot; precalculating the increased power control value and the decreased power control value before receiving the TPC information using the measured transmit power; writing the increased power control value and the decreased power control value to their corresponding registers; receiving the TPC information; and applying the control signal corresponding to the TPC information to a multiplexer of the registers to select the value of appropriate register to the control circuit.
