Abstract
A method of configuring a dual polarized antenna array for communication between a wireless device () and a wireless access network (), the antenna array comprising antenna elements with respective polarizations, where each antenna element is associated with a respective beamforming weight, the method comprising configuring the antenna array for transmission by a first set of beamforming weights w, wherein the first set of beamforming weights is arranged to provide a transmit antenna port connected to antenna elements of a first polarization and of a second polarization, wherein the transmit antenna port is associated with an antenna power pattern; transmitting a first signal via the transmit antenna port on a downlink, DL, from the antenna array to the wireless device; configuring the antenna array for reception by a second wand a third wset of beamforming weights, wherein the second set of beamforming weights wis arranged to provide a first receive antenna port connected to antenna elements of the first and of the second polarization, wherein the third set of beamforming weights wis arranged to provide a second receive antenna port connected to antenna elements of the first and of the second polarization, where each of the receive antenna ports is associated with the antenna power pattern, and where the receive antenna ports have different polarizations; and receiving a second signal on an uplink, UL, from the wireless device () to the antenna array, via the first receive antenna port and the second receive antenna port.
