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： A method is provided for using an antenna array to create two beams (a first beam and a second beam). In one aspect, the method uses dual polarization beam forming, which allows for many degrees of freedom in designing a desired power pattern. The method is well suited for systems with multiple radio chains (e.g., systems with active antennas). The method is also well suited for multi-port systems such as TD-SCDMA. In some embodiments, the method produces two beams where (a) the shape of the power beam pattern for the first beam and the shape of the power beam pattern for the second beam are the same (or substantially the same) in a plurality of directions of interest and (b) the beams have orthogonal (or substantially orthogonal) polarizations in the coverage area.

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).
