摘要： There is provided mechanisms for obtaining channel conditions per antenna element, A method is performed by a wireless radio transceiver device comprising N antenna elements in an antenna array with analog beamforming and being configured to communicate using beams. The method comprises obtaining, for a stationary radio propagation channel, channel conditions for signals received by the wireless radio transceiver device in M beams, where M>1. The method comprises transforming the channel conditions for the M beams to channel conditions for the N antenna elements by using a relation based on beamforming weights that map the N antenna elements to the M beams.

摘要： There is provided mechanisms for beam forming using an antenna array comprising dual polarized elements. A method comprises generating one or two beam ports, wherein the one or two beam ports are defined by combining at least two non-overlapping subarrays. Each subarray has two subarray ports, the two subarray ports having identical power patterns and mutually orthogonal polarization. The at least two non-overlapping subarrays are combined via expansion weights. The expansion weights map the one or two beam ports to subarray ports such that the one or two beam ports have the same power pattern as the subarrays. At least some of the expansion weights have identical non-zero magnitude and are related in phase to form a transmission lobe. The method comprises transmitting signals using said one or two beam ports.

摘要： There is provided beam forming using an antenna array. The antenna array is configured to transmit across an angular sector. The angular sector is divided into at least two sub-sectors by respective port weights being applied to respective physical antenna ports of the antenna array. A respective set of virtual antenna ports is determined for each sub-sector. A first set of reference signals for acquiring channel state information on the set of virtual antenna ports is alternatingly transmitted in each one of the at least two sub-sectors.

摘要： There is provided a dual-polarized N/2-column antenna arrangement. The antenna module arrangement comprises a coupler module. The coupler module is arranged to direct a first summation of energy from signals from a first distinct set of power amplifiers of an N-channel radio to a first single output port connected to a first polarization of a first column of the dual-polarized N/2-column antenna arrangement. The coupler module is arranged to direct a second summation of energy from signals from a second distinct set of power amplifiers of the N-channel radio to a second single output port connected to a second polarization of a second column of the dual-polarized N/2-column antenna arrangement.

摘要： The present invention relates to a node in a wireless communication system (W), the node comprises an antenna arrangement with at least three physical antenna elements and a first beam-forming network. Each physical antenna element has a corresponding physical phase center and antenna port. The physical phase centers are separated by corresponding physical distances, and the physical antenna ports are connected to the first beam-forming network. The first beam-forming network is arranged to transform the physical antenna ports to at least two virtual antenna ports which correspond to virtual antenna elements. Each virtual antenna element has a certain virtual phase center where the virtual phase centers are separated by corresponding virtual distances, where the physical distances differ from the virtual distances. The present invention also relates to a corresponding method.
