Patent ID: 7187664

Claim:
Method for automatically minimizing impact of inter-cell interference and/or interference between co-existing Code Division Multiple Access (CDMA) telecommunication systems, wherein a transceiver unit is located within a radio base station in one CDMA system, said transceiver unit comprises a High Power Amplifier (HPA) unit configured to transmit radio signals to a mobile terminal and a Low Noise Amplifier (LNA) unit configured to receive radio signals from the mobile terminal, the method comprising: automatically controlling a maximum output level of the High Power Amplifier (HPA) unit based on current inter-cell interference and/or interference between co-existing systems by, performing estimations of interference related parameters, wherein performing estimations further includes estimating a relative downlink load level η d , where the relative downlink load level η d is equal to a measured downlink load level (η measured,d ) divided with a predefined target downlink load level (η target,d ) (i.e. η measured,d /η target,d ), and estimating a downlink quality Q d value, and controlling the output power levels of the output signals of the HPA unit by an Automatic Gain Control (AGC) unit connected to said HPA unit by using said estimations.
