摘要： The present invention relates to a solution for efficient handling of radio resources in communication devices in a wireless communication network. In the solution a subset of available antennas to be used is chosen using a method for determining a singular valued metric from a sub matrix related to a full channel matrix. Sub-channel matrices are chosen by deducing the metric and comparing to other sub-matrices. Preferably the best sub-channel matrix is used to determine a suitable full channel matrix to use in communication and this full channel matrix is communicated to each involved communication device.

摘要： A method of and a precoding device and a communication device for precoding transmit data signals in a wireless Multiple-Input Multiple-Output, MIMO, channel transmission scheme for maximizing channel capacity of the MIMO system given available amounts of transmit power. The precoding is expressed in a complex precoding matrix (W), which is calculated involving individual transmit power constraints of the multiple outputs (71, . . . , 7t) of the MIMO channel. The individual transmit power constraints are comprised of predetermined individual output transmit power amplifier (PA1, . . . , PAt) limitations.

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.
