Abstract
The present invention refers to a method for reducing the uplink interferences produced by non-serving user equipments (23) using an enhanced-dedicated channel "E-DCH" in a wireless cellular communication network comprising radio network subsystems (1, 15) that are independent and that present coverage areas that are at least partially overlapping wherein it comprises the following steps: - the establishment of a set up parameter exchange interface (7) between the first (1, 15) and the second (1, 15) radio network subsystem, - when a user equipment attached to a first radio network subsystem (1, 15) is located in the coverage area of a second radio network subsystem (1, 15) independent from the first radio network subsystem, the transmission, through the said established interface (7), of radio link set up information including physical layer parameters information from the first radio network subsystem to the second, - the reception by the second radio network subsystem (1, 15) of uplink coded E-DCH control channel information sent from the user equipment, - the configuration of the second radio network subsystem (1, 15) based on the transmitted radio link set up information in order to decode the received E-DCH control channel information, - the estimation of the uplink interference level produced by the user equipment (23) in the second radio network subsystem based on the decoded E-DCH control channel information, if the estimated uplink interference level in the second radio network subsystem meets a predetermined criterion, - the establishment of a downlink connection between the second radio subsystem and the user equipment (23) based on the transmitted radio link set up information and the sending through the established downlink connection of a request to reduce the uplink power level of the user equipment (23).
