    摘要: There is provided mechanisms for configuring an antenna system having individual antenna elements arranged in at least two antenna subarrays. Each pair of antenna subarrays has a respective first spatial separation. Each pair of the individual antenna elements has a respective second spatial separation. A method is performed by a network device. The method includes obtaining channel measurements for each of the at least two antenna subarrays. Channel covariance information between the subarrays using the obtained channel measurements is determined. Channel covariance information between all individual antenna elements of the antenna system is determined by interpolating the channel covariance information between the subarrays according to a spatial relation between all first spatial separations and all second spatial separations. Combining of the individual antenna elements of the antenna system is controlled based on the determined channel covariance information between all the individual antenna elements.

    摘要: There is provided mechanisms for determining antenna settings associated with at least one network node in a wireless communications network. A method is performed by a network node. The method comprises detecting an event of a network node in the wireless communications network, the event indicating a need for adjustment of at least one antenna setting of the network node and/or at least one other network node in the wireless communications network. The method comprises determining the adjustment of the at least one antenna setting by identifying stored key performance information based on the event. The method comprises determining the adjustment of the at least one antenna setting by assessing a candidate set of possible antenna settings of the network node and/or the at least one other network node, wherein the candidate set is defined by the key performance information.

    摘要: The present disclosure relates to a wireless communication node (1) comprising at least one antenna arrangement (2, 2′, 2″). Each antenna arrangement (2, 2′, 2″) comprises at least one antenna port (3), at least two antenna elements (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b) arranged for providing an antenna beam pattern (8), and a phase control arrangement (9, 9′, 9″) arranged to receive at least one input signal (10) via said antenna port (3) and to determine a plurality of intermediate signal components (11) from said input signal (10) by determining a first set of respective phase shifts (φ1, φ2, 10 φ3, φ4; θ1, θ2, θ3, θ4, θ5, θ6, θ7, θ8) for said input signal (3). The phase control arrangement (9) is further arranged to determine a final signal component (12) for each antenna element (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b) from said intermediate signal components (12) by determining a second set of respective phase shifts (β1, β2, β3, β4: Φ1, Φ2, Φ3, Φ4, Φ5, Φ6, Φ7, Φ8) for said intermediate signal components (12), wherein the second set of phase shifts (β1, β2, β3, β4; Φ1, Φ2, Φ3, Φ4, Φ5, Φ6, Φ7, Φ8) is arranged to provide a lowered gain of the antenna arrangement (2, 2′, 2″) in at least one direction (D). The present disclosure also relates to a corresponding method.
