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： A precoder for an effective channel linking a wireless receiver to a wireless transmitter includes a precoder report and a precoder update report, the effective channel including a propagation channel, transmit filters and receive filters. A structured frequency-selectivity of the effective channel is determined, the structured frequency-selectivity being induced by one or more long term and/or persistent parameters of the effective channel. The precoder update report is generated based on the structured frequency-selectivity. The precoder update report includes frequency-dependent phase compensation which accounts for the structured frequency-selectivity. The precoder report is generated for the effective channel based on channel state information determined for the effective channel. The precoder report and the precoder update report are transmitted to the wireless transmitter. The transmitter determines a transmission operation based on the precoder report and the precoder update report, and transmits data to the wireless receiver in accordance with the transmission operation.

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.

摘要： A network node in a wireless communication network communicates an enhanced Physical Downlink Control Channel (ePDCCH) to a user equipment (UE). This begins with the transmission, to the UE, of a configuration message that indicates the mappings of eDPCCH onto resource elements for both a first eDPCCH set and a second eDPCCH set. The mapping for the first eDPCCH set avoids the use of resource elements already in use by a first type of signal (e.g., a Cell-Specific Reference Signal or CRS), whereas the mapping for the second eDPCCH set avoids the use of resource elements in use by a second type of signal. The choice of an eDPCCH set for transmitting data to a UE may then be dynamically made in order to avoid interference caused by the first or second types of signal.

摘要： The invention relates to a method and an arrangement in a transmitting node (560) for enabling a receiving node (540) to perform measurements on interference caused by transmissions from at least one transmission point (510, 520, 530) controlled by the transmitting node (560) on receptions at the receiving node (540). The transmitting and receiving nodes (560, 540) are comprised in a wireless communications system (500, 600, 700). The transmitting node determines (910) an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference. The transmitting node then transmits (930) at least one interfering signal on said IMR as said interference. The at least one interfering signal comprises at least one of a desired signal, that is expected to be decoded or coherently measured upon by the receiving node (540) or another node (550) served by said transmitting node (560), and another signal, that is not expected to be decoded or coherently measured upon by any node (540, 550) served by said transmitting node (560). The desired signal is transmitted in place of the another signal as said at least one interfering signal on one or more TFREs of the IMR when the at least one transmission point is to transmit the desired signal to the receiving node (540) or to the another node (550). The another signal is transmitted on TFREs of said IMR where no desired signal is transmitted and the another signal is muted on TFRE's of said IMR where the desired signal is transmitted.
