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.

摘要： A controlling station (110, 400) comprising an antenna arrangement (420) with a number of antennas, which each covers one of a number of adjacent cells, with a main beam with a beamwidth that extends into two immediately adjacent cells. The controlling station (110, 400) is adapted to: - transmit on a control channel on a first number of antennas, - measure the output power on the traffic channels on the first number of antennas, - if the traffic channel output power on any of said first number of antenna is above a threshold, transmission on the control channel is activated on a second number of antennas, - measure the traffic channel output power on each antenna in the antenna arrangement, - if the measured traffic channel output power on an antenna is below a second threshold and the traffic channel on the antennas of both adjacent cells is active, the control channel transmissions on that antenna are deactivated.

摘要： A solution is disclosed for minimizing the amount of hardware and hardware accuracy requirements to simultaneously give the feature of both cell and narrow beams transmission, while enabling methods for capacity/coverage increase. The main property utilized by the present invention for maintaining cell-coverage pattern control, when radiating information in two simultaneous beams, is to use orthogonal polarization states for the two beams. The two orthogonal polarization states may for instance constitute linear polarization slanted at +45° and -45°, respectively. The dedicated broadcast transmission needs to be conveyed defining the total cell coverage area. The total cell coverage area is matched by the coverage of the two fixed narrow-beams. The broadcast signal transmission is divided into two signal streams/paths, one for each of the two fixed narrow-beams (no coherency requirements existing between the two parallel signal streams/paths). The two broadcast signal streams/paths are combined by means of combiner units with the dedicated combined signals from all fixed narrow-beam selected users in each of the two branches. The signals to the two antennas are then transmitted having an orthogonal polarization.

摘要： The invention relates to adjusting the shape of the antenna beam (20) of a directional antenna (120) in a communications system (1). According to the invention, the antenna beam (20) is divided into at least a handover beam sector (24) and a main beam sector (22). The shape of the at least two beam sectors (22; 24) are then adjusted based on different requirements and objectives. The shape of handover beam sector (24) is adjusted based on the handover parameter settings of the communications system (1), e.g. by adjusting the angular interval of this handover beam sector (24) based on the parameter settings. Optionally, the shape of the main beam sector (22) is adjusted by maximizing the antenna gain of the directional antenna (120) within this beam sector (22).
