    • 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.
    • 本发明涉及在站内切换过程中的数据处理。 基站(100)的至少两个定向天线(140; 160)接收承载来自位于由重叠的无线电覆盖(14; 14)定义的站内切换区域(15)内的移动单元(400)的信号的用户数据。 16)的天线(140; 160)。 定向天线(140; 160)执行接收的数据信号的初始数据信号检测,导致检测到的用户数据,这通常导致天线(140; 160)的无线电性能的损失。 来自定向天线(140; 160)的检测到的用户数据然后被联合处理以产生经处理的用户数据。 通过提供切换区域(15)内的定向天线(140; 160)的差分天线增益来补偿性能损失。 结果,获得了作为现有技术解决方案的该领域(15)中类似的无线电覆盖,但是具有较不复杂的天线相关设计。
