    Abstract: An advanced antenna system, AAS, comprising a plurality of antenna elements (210), where the AAS extends on a surface (S) defined by a normal vector (N), where an x-direction (x) at a point (P) on the surface (S) is parallel to the normal vector (N) at the point (P), where a z-direction (z) at the point (P) on the surface (S) is tangent to the surface (S) and orthogonal to the x-direction (x), where a y-direction (y) at the point (P) on the surface (S) is tangent to the surface (S) and orthogonal to both the x-direction (x) and the z-direction (z), where the antenna elements (210) are arranged in at least three columns (230) extending in the z-direction (z) on the surface (S), where each column (230) comprises at least two antenna elements (210), where at least two of the columns (230) are arranged offset in the z-direction at respective non-zero offset distances (O), relative to a reference column (REF) of the AAS, such that a first offset distance of a first column differs from a second offset distance of a second column in the AAS.

    Abstract: Embodiments of the present disclosure provide methods, apparatuses, and computer products for base station antenna calibration. A method is implemented in a base station (402-1) for a cellular communications system (400). The method includes selecting (500), from a plurality of User Equipments, UEs, (412), assistant UEs (412-1) to assist the base station (402-1) with antenna calibration, wherein selecting (400) the assistant UEs (412-1) is based upon criteria that includes UE channel state information, CSI, from the UEs (412); one or more uplink channel characteristics of an uplink channel from the UEs (412) to the base station (402); a UE capability of the UEs (412), UE traffic information related to the UEs (412); and any combination thereof. A further step is obtaining (514) antenna calibration assistance information from the assistant UEs (412-1), the antenna calibration assistance information being information that is used by the base station (402-1) for antenna calibration.

    Abstract: A method for compensating a movement of an antenna structure having a directive antenna mounted thereto is disclosed. The method comprises obtaining sensor data from a motion sensor, where the sensor data is indicative of the movement of the antenna structure relative to a reference orientation. Moreover, the motion sensor is associated with a set of calibration parameters such that when applied to the obtained sensor data, calibrated sensor data is formed. Further, the method comprises generating a compensation signal at an output for controlling a beam direction of the directive antenna based on the formed calibrated sensor data such that the beam direction is an intended direction of the directive antenna and such that the (unwanted) movement of the antenna structure is compensated. The method further comprises re-calibrating the motion sensor in order to generate a set of calibration coefficients upon either one of an expiry of a predefined time period, a counter reaching a counter threshold, or upon a measured antenna parameter or signal parameter diverging from a parameter range. Once, one of these conditions are fulfilled, the re-calibration is performed by obtaining a received signal strength indication (RSSI) while the beam direction is controlled based on the generated compensation signal, generating the set of calibration coefficients based on the obtained RSSI, and updating the set of calibration parameters for the motion sensor with the determined set of calibration coefficients.
