Abstract
Radio resources are allocated to communication between a mobile station and a base station. The available set of radio resources may comprise radio resources primarily assigned to a neighboring cell if the 5 mobile station experience an instantaneous low level of co-channel interference from such neighboring cells. The existence of interference is preferably deduced from signal quality measurements of pilot signals. The allocation may concern uplink and/or downlink communication. Devices for performing the measurements are located in the mobile station, while devices for performing the evaluation, selection and actual allocation can be placed in different parts of the communications system-in the mobile station, in a base station or in a core network node, or as a distributed means.

19. A base station of a radio communications system, comprising:
-
evaluation means arranged to determine a radio resource reuse area occupied by a mobile terminal (occupied reuse area) based on a quality report from said mobile terminal, the quality report including a report of quality measures of signals transmitted from a plurality of base stations measured at said mobile terminal; selection means arranged to select a set of one or more radio resources allowed to be used (allowed resource set) based on the occupied reuse area; and allocation means arranged to allocate one or more radio resources from the allowed resource set for use in actual communication (actual radio resource(s)) between said mobile terminal and said base station, wherein the occupied reuse area is one of a plurality of radio resource reuse areas of said base station, the plurality of radio resource use areas including at least an inner part that encloses said base station, an intermediate part that encloses the inner part, and an outer part that encloses the intermediate part and bounded by a cell of said base station, and a reuse factor of radio resources is highest for the outer part and lowest for the inner part. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
