Patent CA-2335095-A1 (CA)
Inventor: NAGHIAN SIAMAK
IPC: H04J13/00
Filed: 1999-07-14
Abstract: A method for controlling transmission power in a radio system and in a WCDMA system network in particular for maximizing cell capacity. An acceptable transmission power margin and an optimum power level, which may change specifically for each connection and service class, are determined for the transmission power. Transmission power is adjusted using power control steps utilizing am incoming power control command and previous power control steps.      The power control step size is adjusted as a sum of a fixed and a variable dynamic step size where the dynamic value is obtained on the basis of the measured value and the target value of the signal-to-noise ratio. Information on the network state can be obtained by comparing AC and LC data and the cell capacity can be maximized by controlling the amount of transmission power calculated by the mobile station before the final power transmission.
