摘要： The technology 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 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： A method and arrangement for enabling communication of data between a UE and a first base station in a cellular communication network further comprising the second base station, and the second base station is connected to the first base station via a communication interface. A scheduling request is received from the first base station. The scheduling request is based on a suggested scheduling which is determined by the first base station, and the suggested scheduling concerns the communication of data. Scheduling information is determined based on the scheduling request, and the scheduling information is transmitted to the UE. By determining a suggested scheduling in a micro base station, but transmitting scheduling information from an overlaying macro base station, local awareness of communication conditions may be applied, and interferences from neighboring micro base stations may be decreased.
