摘要： Example embodiments presented herein are directed towards an eNodeB, and method therein, for generating downlink communications in a multiple antenna system. The method comprises transmitting, to a number of user equipments, a plurality of reference signals, where each signal is beamformed in a distinct direction within at least one correlated domain (e.g., elevation and/or azimuth). The eNodeB receives at least one CSI report from a specific user equipment and determines a primary reference signal based on, for example, the at least one CSI report. The eNodeB may thereafter generate downlink communication signals for antenna element(s) and/or subelements of the multiple antenna system. The downlink communication signals are beamformed into a transmitting direction that aligns most closely with a beamforming direction of the at least one primary reference signal, as compared to any other beamforming direction of the reference signals.

摘要： The initialization of the CoMP Resource Management Set for a given mobile terminal is based, at least in part, on an estimation of the mobile terminal's geographical location, which can be estimated using network positioning of the mobile terminal. One example method begins with the acquisition (410) by a network node of a geographical position estimate for the mobile terminal of interest. The network node then selects (420) a set of one or more CSI-RS resources for measurement by the mobile terminal, based on the estimated geographical position of the mobile terminal. Finally, the network node configures the mobile terminal to measure the selected CSI-RS resources by sending (430) control information identifying the set to the mobile terminal.

摘要： Embodiments herein relate to a method in a radio base station (12) for transmitting a data signal to a user equipment (10) in a radio communications network. The radio base station (12) is connected to an active antenna array of a number of active transmitting antennas and the radio base station (12) serves the user equipment (10) in the radio communications network. Each active transmitting antenna comprises sub elements. The radio base station (12) transforms a precoded data signal using a transformation, which transformation directs signals vertically. Furthermore, the radio base station (12) transmits the transformed data signal over at least one sub element to the user equipment (10). The transmitted data signal is enabled to be directed vertically, and the transformed data signal is limited to be transmitted in a direction within a range of elevation angles.
