摘要： The invention 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.

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).

摘要： The invention discloses a wireless telecommunications system for stationary or semi-stationary equipment, Q and comprises a main node (C) and a first plurality (SI-S3) of terminals belonging to the same access subset and arranged to receive Q from and transmit to the main node (C). The main node transmits in at least one beam and receives in at least two beams, and the system comprises means (C) for indicating to terminals that they mayor may not transmit to the central node (C). Based upon certain criteria, two or more terminals (Si-SN) located in different receive beams of the main node (C) may be given permission to transmit to the central node simultaneously. Suitably, two or more terminals which are given permission to transmit simultaneously do so using the same frequency, or the same code or the same time slot.
