DATA PROCESSING IN INTRA-SITE HANDOVER

摘要

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
