Abstract
In the present invention, in a cellular communication system using frames (20) of communication resources in time and/or frequency domain, the communication resources (22) are divided into at least two regions (24, 26, 28). A first region (24) has a higher reuse in time and/or frequency domain than a second region (26, 28). The first region is a hybrid region (24), in which the communication resources individually are allocable for either uplink or downlink communication on a cell-to-cell basis. The second region is preferably a dedicated region (26), in which all communication resources have either uplink or downlink allocation. A third region (28) is preferably also present, in which all communication resources are allocated in the opposite direction to the second region (26). In preferred embodiments, the actual allocation of the hybrid region (24) is based on the traffic situation in each individual cell.
