摘要： Some of the example embodiments presented herein are directed towards an eNodeB (401), and corresponding method therein, for establishing beamforming for downlink communications in a multiple antenna system. The eNodeB (401) may be configured to transmit a plurality of reference signals, where each reference signal is beamformed into a distinct direction with in at least one correlated domain (e.g., an elevation and/or azimuth domain). The eNodeB (401) may thereafter generate beamformed downlink communications for antenna elements and/or subelements based on received signal quality assessments of the plurality of reference signals. Some example embodiments may be directed towards a user equipment (505), and corresponding methods therein, for establishing beamforming for downlink communications. The user equipment (505) may be configured to receive the plurality of reference signals and provide signal assessments of the reference signals based on measurements performed by the user equipment (505). The user equipment (505) may thereafter transmit the signal quality assessments to the eNodeB (401) and receive beamformed downlink communications based on the signal quality assessments.

摘要： Example embodiments presented herein are directed towards an eNodeB (401), and method therein, for establishing beamforming for downlink communications in a multiple antenna system. The eNodeB may be configured to receive, from a user equipment, a plurality of signal quality assessments which correspond to a distinct direction within at least one correlated domain (e.g., an elevation and/or azimuth domain). Based on the signal quality assessments, at least one first and second signal quality assessment may be identified according to a predetermined signal characteristic. Thereafter, a transmission direction may be determined based on the at least one first and second signal quality assessment and associated directions within the at least one correlated domain. Based on the determined transmission direction, downlink communications may be transmitted to the user equipment.

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 fay 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 transforming a data transmission signal in a radio communications network. The radio base station (12) is connected to an active antenna array of a first number of active transmitting antennas, which each active transmitting antenna comprises sub elements. The radio base station (12) comprises a precoder codebook comprising precoders for transmitting signals in a diversified manner for a second number of antenna ports. The radio base station serves a user equipment in the radio communications network. The radio base station (12) precodes the data transmission signal with a precoder selected from the precoder codebook. The radio base station (12) furthermore transforms, linearly, the precoded data transmission signal by neutralizing a direction of the precoded data transmission signal and then directing the precoded data transmission signal vertically. The precoded data transmission signal is thereby enabled to be vertically adjusted towards the user equipment (10).

摘要： A transmitting radio node (10) precodes a transmission from an antenna array, which includes antenna elements arranged along at least two axes, using a main codebook which is representable as a Kronecker product of a first codebook and a second codebook, where the first codebook comprises predetermined sub-precoders and the second codebook comprises configurable sub-precoders. A receiving radio node (20) may benefit from adaptive beamforming made possible by the configurability of the main codebook, while still using a stable format, which remains valid also after reconfiguration, for the exchange of reference signals and corresponding feedback information.

摘要： According to one aspect of this disclosure, the configuration of which Interference Measurement Resources, "IMRs", a given user equipment, "UE", should measure for Channel State Information, "CSI", reporting is made more or less invariant to dynamic traffic variations affecting the set of Coordinated Multi-Point, "CoMP", transmission points used for serving the UE, or to the use of dynamic blanking for those transmission points. These goals are achieved at least in part by configuring one or more of the transmission points to follow a first rule embodying a negative logic. According to the first rule, the transmission point transmits on a given IMR if it has been deemed as being not likely to transmit data at a time relevant to the IMR, and, conversely, to not transmit the IMR if it has been deemed as being likely to transmit data at a time relevant to the IMR.
