Patent ID: 6985741

Claim:
A method for determining channel quality in a radio communication network comprising the steps of: measuring, by the network, a transmitted code power associated with a base station; acquiring, by the network, a power associated with a pilot channel; receiving, by the network from a mobile station, a measurement of a quality of the pilot channel received by the mobile station; measuring, by the network, a transmitted carrier power; and, determining downlink channel quality using the measured transmitted code power, the acquired power associated with the pilot channel and the received measurement of the quality of the pilot channel received by the mobile station, wherein the step of determining downlink channel quality comprises a step of determining a channel quality based on interference within a cell associated with the base station using the following formula: (Transmitted Code Power/Primary CPICH Power)×(1/((1/Received CPICH — E c /I o I RX )−(Transmitted Carrier Power/Primary CPICH Power))) wherein the Primary CPICH Power is the power associated with the pilot channel, the Received CPICH — E c /I o I RX is the measurement of the power of the pilot channel received by the mobile station.
