摘要： The present invention provides a unified, rank independent mapping between antenna ports and group/code pairs. Each antenna port is uniquely associated with one code division multiplexing (CDM) group and one orthogonal cover code (OCC). The mapping between antenna ports and group/code pairs is chosen such that, for a given antenna port, the CDM group and OCC will be the same for every transmission rank.

摘要： Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.

摘要： Downlink control information (DCI) extensions to support 3GPP Rel-10 functionalities comprise minimal extensions of DCI format 2B. In some embodiments, only two extra bits (20) are introduced to signal rank up to eight, by reusing the Scrambling Identity bit (16) while at the same time supporting different MU-MIMO dimensioning for the important cases of rank-1 and rank-2. This new DCI format can potentially support not only single cell downlink transmission but also some other Rel-10 functionalities, e.g. CoMP or relaying/HetNet.

摘要： A method and an arrangement in a radio network node for adapting transmission power of resource elements for demodulation reference signals, referred to as “reference elements” are provided. The radio network node is configured for multiple-input multiple-output transmission, referred to as “MIMO transmission”, to a user equipment. The MIMO transmission comprises at least three layers. Two consecutive subcarriers of a resource block carry at least three reference elements. A first subcarrier of the resource block carries data elements. The radio network node adapts transmission power of said at least three reference elements such that an average transmission power, over said two consecutive subcarriers, of said at least three reference elements is equal to a transmission power, for the first subcarrier, of the data elements for said at least three layers. The radio network node uses the adapted transmission power to transmit, to the user equipment, said at least three reference elements.

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： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node and a receiving node. When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： A method for wirelessly transmitting data using a plurality of transmission layers includes estimating a number of data vector symbols to be allocated to one or more user data codewords during the subframe and determining a number of bits in the one or more user data codewords. The method also includes calculating a nominal number of control vector symbols to allocate to control information based, at least in part, on the estimated number of data vector symbols and the determined number of bits in the one or more user data codewords. Additionally, the method includes determining an offset value based, at least in part, on a number of layers over which the wireless terminal will be transmitting during the subframe and calculating a final number of control vector symbols by multiplying the nominal number of control vector symbols and the offset value. The method also includes mapping one or more control codewords to the final 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.
