摘要： A system and method to instruct a User Equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.

摘要： The invention relates to methods and arrangements in a transmitting node for enabling a receiving node to perform measurements on interference caused by transmissions from at least one transmission point controlled by the transmitting node on receptions at the receiving node. The transmitting and receiving nodes are comprised in a wireless communications system. The transmitting node determines an interference measurement resource, IMR, for the receiving node. The receiving node is expected to measure interference on the IMR. The transmitting node then transmits at least one interfering signal on the IMR. The at least one interfering signal is not expected to be decoded or coherently measured upon by any node served by the transmitting node.

摘要： Some example embodiments presented herein are directed towards an eNodeB, and corresponding method therein, for establishing beamforming for downlink communications in a multiple antenna system. The eNodeB may 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 may 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, and corresponding methods therein, for establishing beamforming for downlink communications. The user equipment may receive the plurality of reference signals and provide signal assessments of the reference signals based on measurements performed by the user equipment. The user equipment may transmit the signal quality assessments to the eNodeB and receive beamformed downlink communications based on the signal quality assessments.

摘要： Some embodiments provide a method in a wireless device for reporting channel state information, CSI, for a CSI process. The CSI process corresponds to a reference signal resource and an interference measurement resource. According to the method, the wireless device obtains an adjustment value associated with the CSI process. The wireless device estimates an effective channel based on one or more reference signals received in the reference signal resource, and applies the adjustment value to the estimated effective channel, thereby obtaining an adjusted effective channel. Furthermore, the wireless device determines channel state information based on the adjusted effective channel, and on interference estimated based on the interference measurement resource. Finally, the channel state information is transmitted to a network node.

摘要： Some of the example embodiments presented herein are directed towards an eNodeB (401), and corresponding method therein, for providing data transmission in a multiple antenna system. The eNodeB (401) may be configured to receive a plurality of signal quality assessments and a CSI report from a user equipment.

摘要： A method for wirelessly transmitting user data and at least a first type of control information using a plurality of transmission layers including encoding bits of a first type of control information to form one or more control codewords and encoding bits of user data to form one or more user data codewords. The method also includes generating a plurality of vector symbols based on the control codewords and the user data codewords. Each vector symbol includes a plurality of modulation symbols that are each associated with a transmission layer over which the associated modulation symbol will be transmitted. Generating the plurality of vector symbols includes interleaving bits of the one or more control codewords and bits of the one or more user data codewords so that the first type of control information is carried in modulation symbols associated with the same transmission layers in all the vector symbols transmitted during the subframe that carry the first type of control information. The method also includes transmitting the plurality of vector symbols to a receiver over a plurality of transmission layers.

摘要： A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords to be transmitted during a subframe and calculating a number of control vector symbols to allocate to control information during the subframe. The number of control vector symbols is calculated based at least in part on the number of bits in the one or more user data codewords to be transmitted during the subframe and an estimate of the number of vector symbols onto which the one or more user data codewords will be mapped. The estimate of the number of vector symbols depends, at least in part, on the number of control vector symbols to be allocated to control information. The method also includes mapping one or more control codewords to the calculated number of control vector symbols and transmitting vector symbols carrying the one or more user data codewords and the one or more control codewords over the plurality of transmission layers during the subframe.
