Abstract
The invention relates to mobile cellular communication systems in which asymmetric access to a time division duplex (TDD) communication channel is provided. The channel is divided (by TDD) into slots which are allocated to either uplink communication or downlink communication by the base station in each cell. Timing of slots, and thus of compulsory uplink and downlink slots, is coordinated across the cells of a system.
