摘要： A beam having the best performance for the present downlink transmits the signal carrying information. In another beam transmitted, in a corresponding manner having the best performance in regard to the next mobile station to be communicated in a next time slot, a signal is created which has a low cross correlation relative to the present signal carrying information. The average power in the direction to the next mobile station to be communicated in the next TDMA time slot will be given by the sum of the average power of the two signals after amplification by the respective antenna pattern. This takes place because the cross correlation between the signals is low due to which fact the summed signal will show a power addition but not a coherent addition. This is feasible as the summed signal is not be decoded by the next mobile station, but used entirely as a measurement of power. To further improve operation, the interleaving beams produced by two offset Butler Matrixes and then applied to a combiner may be used.

摘要： Multipoint wireless communications are coordinated in cells with radiation that is emanated from antennas in an inward direction. In an example embodiment, an apparatus includes a first antenna, a second antenna, a third antenna and a controller. The first antenna emanates radiation from a first location in an inwardly direction for a cell. The second antenna emanates radiation from a second location in an inwardly direction for the cell. The third antenna emanates radiation from a third location in an inwardly direction for the cell. The controller coordinates the emanation of the radiation via the first, second, and third antennas so as to reduce intra-cell interference for remote terminals located within the cell. The coordination may be effected in accordance with one or more coordinated multi-point (transmission/reception) (CoMP) techniques. Different numbers of sub-cells and antennas per cell and different CoMP cell organizations may be implemented.

摘要： The invention relates to an apparatus and a method for simultaneously generating, with the same radio antenna apparatus (10), a number of narrow beams and a wide beam, covering substantially the same area covered by the individual pointed beams together. The radio antenna apparatus (10) comprises an antenna array (3) a Butler matrix (2) connected to the antenna array and a set of amplifying modules (1a, . . . 1h). The activation of each of the inputs (L1, . . . , L8) of the radio antenna apparatus corresponds to a radiation pattern characterized by a narrow beam with a high antenna gain from the antenna array (3). By simultaneously activating the beam ports with the same signal with suitable phase relationships a superimposition of the radiation patterns to which the activated beam port corresponds is achieved in such a way that a wide beam is generated. Since all amplifying modules (1a, . . . , 1h) are used simultaneously, the lower antenna gain of the wide beam will be compensated by a corresponding higher amplification. The wide beam will therefore have substantially the same range as the narrow beams.
摘要翻译：本发明涉及一种利用相同的无线电天线装置（10）同时产生多个窄波束和宽波束的装置和方法，该窄波束和宽波束覆盖由各个尖波束覆盖的基本相同的区域。无线电天线装置（10）包括天线阵列（3）连接到天线阵列的巴特勒矩阵（2）和一组放大模块（1a，...，1h）。无线电天线设备的每个输入（L1，...，L8）的激活对应于由天线阵列（3）具有高天线增益的窄波束表征的辐射图。通过以适当的相位关系同时激活具有相同信号的波束端口，实现激活的波束端口对应的辐射图案的叠加，使得产生宽波束。由于同时使用所有放大模块（1a，...，1h），所以宽波束的较低天线增益将通过相应较高的放大来补偿。因此，宽光束将具有与窄光束基本相同的范围。

摘要： A method and a system for calibrating the reception and transmission of an antenna array for use in a cellular communication system is disclosed. The calibration of the reception of the antenna array is performed by injecting a single calibration signal into each of a number of receiving antenna sections, in parallel. The signals are collected after having passed receiving components that might have distorted the phase and amplitude. Correction factors are generated and applied to received signals. The calibration of the transmission of the antenna array is performed in a similar way. A single calibration signal is generated and injected into each of a number of transmitting antenna sections, one at a time. The signals are collected, one at a time, after having passed transmitting components that might have distorted the phase and amplitude. Correction factors are generated and applied to signals that are to be transmitted.
