Abstract: A wireless communication system comprising a first network node and a wireless device is provided. The system is adapted to establish communication between the first network node and the wireless device. The device is adapted to obtain information related to a geographic location of the device, to transmit the information related to the geographic location to the network node, and to transmit a Sounding Reference Signal to the node. The node is adapted to receive information related to a geographic location of the device, and to determine an antenna configuration of the network node for communicating with the device via a directive antenna, based on the geographic location of the device. A network node is adapted to communicate with the device by the first network node, via the directive antenna, by means of the determined antenna configuration.

Abstract: The present disclosure relates to an antenna system (1, 1?) comprising: —a first set of antenna ports (2), —a second set of antenna ports (3) separate from the first set of antenna ports (2), —a third set of antenna ports (28) that at least partly comprises each one of the first set of antenna ports (2) and the second set of antenna ports (3), —a transmitter arrangement (4, 4?), and —a receiver (5, 5?).

Abstract: The disclosure relates to a node in a wireless communication arrangement, the node comprising an antenna arrangement that comprises a first and second inverted F antenna. The inverted F antennas comprise a corresponding first and second feed connection, first and second ground connection and a corresponding first and second radiating element mainly extending from the respective ground connection along a corresponding first and second longitudinal extension. The inverted F antennas are arranged on, or in, a plane. Furthermore, the first and second radiating elements are extending in opposite directions along their respective longitudinal extensions from the respective ground connections, the first longitudinal extension and the second longitudinal extension being mutually parallel. The closest distance between the first radiating element and the second radiating element exceeds 0.4*?0, where ?0 is the wavelength for the center frequency of the frequency band for which the inverted F antennas are intended.
