摘要： Indication(s) of a configuration of first interference measurement resources in first subframe(s) and of a configuration of second interference measurement resources in second subframe(s) are received at a first BS and from a second BS using an interface between the first and second BSs. The first BS transmits zero or low power REs that coincide with the REs belonging to the first interference measurement resources in the first subframe(s). The first BS transmits full power REs that coincide with the REs belonging to the second interference measurement resources in the second subframe(s). The first interference measurement resources in the first subframe(s) are to be used by a UE (e.g., attached to the second base station) to measure interference for zero or low power REs and the second interference measurement resources in the second subframe(s) are to be used by the UE to measure interference for full power REs.

摘要： A method of operating an array of antennas in a wireless communication system to provide user-specific azimuth and elevation beamforming is described. The method includes providing a product codebook structure consisting of both an azimuth and elevation portion. A receiver receives reference signals from a transmitter corresponding to both the azimuth and elevation portions of the array of antennas. The method also includes determining the index of the azimuth codebook portion of the product codebook from the azimuth portion of the received reference signals and determining the index of the elevation codebook portion of the product codebook from the elevation portion of the received reference signals.

摘要： A method includes receiving a number of indicators from a number of UEs. Each value of an indicator corresponds to entry(ies) of a codebook the corresponding UE recommends to be used for transmission. The method includes assigning the UE to a number of groups, including a first group of UEs having values of indicators corresponding to first codebook entries that when applied to an antenna array produce a pattern in elevation that steers a beam away from an underlying cell, and a second group of UEs having values of indicators corresponding to second codebook entries that are different from the first codebook entries. The method includes transmitting, in a first set of RBs having a first characteristic, to the UEs in the first group and transmitting, in a second set of RBs having a second, different characteristic, to the UEs in the second group. Apparatus and program products are disclosed.

摘要： Systems and techniques for crosstalk estimation. One or more user devices feed back preceding matrix indicator rank information to one or more base stations, which generated channel state information reference sources, at least one of which includes weightings based on the preceding matrix indicator rank information. One or more user devices estimates channel information based on active preceding matrix indicator information received by the base station from at least one user device. One or more user devices computes channel estimates for a desired transmission channel and one or more other potential transmission channels associated with other user devices and performs crosstalk estimation for the estimated channels. Crosstalk estimation information is fed back to a base station, which performs scheduling based at least in part on the crosstalk estimation from the one or more user devices.

摘要： A method to use RSs for per-user elevation beamforming is described. An eNB sends, to a UE, an indication of which RSs in a plurality of RSs sound in the elevation dimension and which RSs in the plurality of RSs sound in the azimuthal dimension. Then, the eNB sends to the UE, the plurality of RSs using a plurality of antenna. The UE separates the plurality of RSs into the first portion and the second portion based at least in part on the indication and sends elevation and azimuthal feedback based on the received RSs to the eNB. The eNB determines beamforming weights for the plurality of antenna based at least in part on the elevation feedback and the azimuthal feedback. Apparatus and computer readable media are also described.
