Abstract
In a cellular wireless network methods and apparatus are disclosed for a signal broadcasting scheme that can be individually augmented for users with poor reception. The network employs a first downlink channel (broadcast CH) for broadcasting data to all mobile stations (S 1 S2 S3) a second downlink channel (regular CH) for sending signals to a specific mobile station in a cell and an uplink channel for feeding back information to the base station. To achieve a certain user reception quality the system adjusts its broadcasting parameters based on the statistical analysis of the feedback data (feedback). If some users still require better reception the system individually augments their broadcast signals via the second downlink channels. Methods and apparatus are also disclosed for synchronization of data distribution by base stations (12) which in part allows the receivers to combine the receiving signals and improve their reception quality.
