摘要： The technology involves data processing during intra-site handover procedures. At least two directional antennas of a base station receive user data carrying signals originating from a mobile units positioned in an intra-site handover area defined by the overlapping radio coverage of the antennas. The directional antennas 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. The detected user data from the directional antennas is then jointly processed to generate processed user data. The performance loss is compensated by providing differential antenna gain of the directional antennas within the handover area. As a result, a similar radio coverage in this area as prior art solutions is obtained but with a less complex antenna-related design.
