Abstract: In a method of interference mitigation in a multi user detection capable radio base station in a communication system, which radio base station comprises a set confined detection modules (11,12,13,21,22,23), at least one of which is capable of handling multiple user connections, first (10) and at least a second (20) subset of detection modules are formed from said set, wherein the second set comprises at least one interference mitigation capable detection module (21). Interference information from the first subset is communicated to the second subset, interference originating in user connections of the first subset are then mitigated from the user connections of the second subset. Subsequently, interference is mutually mitigated between the connections within the interference mitigation capable detection module.

Abstract: The invention involves data processing during intra-site handover procedures. At least two directional antennas (140; 160) of a base station (100) receive user data carrying signals originating from a mobile units (400) positioned in an intra-site handover area (15) defined by the overlapping radio coverage (14; 16) of the antennas (140; 160). The directional antennas (140; 160) performs an initial data signal detection of the received data signals resulting in detected user data, which typically results in a loss of radio performance of the antenna (140; 160). The detected user data from the directional antennas (140; 160) is then jointly processed to generate processed user data. The performance loss is compensated by providing differential antenna gain of the directional antennas (140; 160) within the handover area (15). As a result, a similar radio coverage in this area (15) as prior art solutions is obtained but with a less complex antenna-related design. ® KIPO & WIPO 2007
