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： 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 present invention relates to radio systems and, more particularly, to a method and apparatus for receiving radio signals with the aid of beams generated by antenna assemblies. For each of the beams in a first of the antenna assemblies there is a beam in the second of the antenna assemblies that covers the same space area. Signals received by the second are delayed relative to signals received by the first of the antenna assemblies. Then signals from the first antenna assembly are combined with signals from the second of the antenna assemblies. The combined signals derive from beams covering the same space area. Each combined signal is then radio received in a joint radio receiver. A DOA-estimation can be calculated on the basis of radio received signals derived from all beams.

摘要： Random access coverage is assured while at the same time supporting high uplink data rates in a same service area served by a base station. A set of radio resources are shared by multiple mobile terminals for transmitting uplink to the base station including requests for access to service from the base station and transmissions for active connections with the base station. A first repeating time period and a second different repeating time period are defined. Uplink transmission grants are scheduled for active connections that permit use of a greater amount of the radio resources during the first repeating time period. Uplink transmission grants are also scheduled for active connections that permit use of a smaller amount of those resources during the second repeating time period. At least some random access requests to the base station are controlled to occur only during the second repeating time period.

摘要： A Radio Base Station (RBS) and method of operating the same are provided. The RBS may enable a fast and flexible reconfiguration of the system from a first configuration to a second confirmation where the RBS is triggered to initiate a system reconfiguration and the reconfiguration is performed by starting a new cell with the wanted new configuration in parallel with the original cell. During a certain time period, both the original and the new cell are available. Thereafter, the original cell is shut down. The time offset between the start up of the new cell and the shut down of the original cell may be long enough to ensure that user equipment associated with the original cell can be handed over or can reselect the new cell. The time offset may be short enough to reduce the interference between the original and new cells.
