HANDLING CONTROL CHANNELS IN A WCDMA SYSTEM

摘要

A radio base station for use in a Wideband Code Division Multiple Access network. The radio base station comprises a receiver for receiving radio signals transmitted over the air by users, and a first processor for processing the received signals in order to recover signals for a first group of users, the “cancellers”, and a first set of control signals for a second group of users, the “cancellees”. The radio base station further comprises an interference canceller for performing interference cancellation on the received signals using the recovered signals in order to generate an interference cancelled signal, a second processor for subsequently processing the interference cancelled signal in order to recover a second set of control signals for the cancellees, and a controller for using the control signals to control the transmission of data towards said cancellees.
