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： 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： An object of the present invention is to enable coordination of VP/HP polarizations generated by cross-polarized, i.e. orthogonally polarized antenna configurations, of one radio device with another radio device. The object is achieved by a method in a first eNB (100c) of coordinating polarizations of the first eNB with polarizations of an additional eNB (100a). The polarizations are generated by an antenna configuration comprising at least two orthogonally polarized antennas. The first and additional eNB (100c, 100a) communicate wirelessly with a UE (150a). The method comprises the steps of establishing a first amplitude and/or phase offset of the antenna configuration generating a vertical or horizontal polarization, and a second amplitude and/or phase offset of the antenna configuration generating a polarization orthogonal to said polarization generated by the first amplitude and/or phase offset, defining the polarization generated by the first amplitude and/or phase offset to be vertical and the polarization generated by the second amplitude and/or phase offset to be horizontal, determining a polarization of the UE, and coordinating the defined polarizations with polarizations of the additional eNB based on the determined UE polarization.

摘要： The present invention relates to methods and arrangements in a wireless communication system that enable the allocation of resources to UEs based on measurements of their antenna polarization, in order to suppress the interference between different UEs at a very low overhead cost. This is achieved by a solution where the scheduling unit retrieves information about the polarization of the UE antenna configurations, and based on this information allocates radio resources to the different UEs, with the aim to minimize the interference. The scheduling unit may retrieve the information from the RBSs or from the UEs. The RBS and the UE will determine the polarization and transmit information regarding this polarization to the scheduling unit. The scheduling unit coordinates the allocation of resources with other scheduling units if necessary.

摘要： The present invention relates to a node in a wireless communication system, the node having a central point and comprising at least two antenna functions. Each antenna function is arranged to cover a corresponding sector area, the sector areas being positioned around the central point successively such that each sector area is adjacent to at least one other sector area separated by corresponding borders. The polarization of at least one of said antenna functions is variable between the borders of the corresponding sector area such that for each border, the polarizations of the antenna functions at each side of the border are essentially orthogonal at the border. The present invention also relates to a corresponding wireless communication system and corresponding antenna functions.

摘要： The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross-polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.
