  • Patent number: 9237459
    Abstract: A method includes receiving in a receiver transmissions from a serving cell that serves the receiver and from one or more neighbor cells. The transmissions are received via multiple receive antennas to produce multiple respective output signals. The multiple output signals are weighed with respective weights, and the weighted output signals are combined to produce a combined output signal. The weights are selected so as to form a composite antenna pattern having a first antenna gain in one or more first directions that point toward the neighbor cells, and a second antenna gain, lower than the first antenna gain, in a second direction that points toward the serving cell. Characteristics of the one or more neighbor cells are measured by processing the combined output signal in which the transmissions received from the serving cell are attenuated.

  • Patent number: 9178591
    Abstract: A method in a mobile communication terminal includes holding a definition of a sub-sampled codebook identifying precoding matrices to be used for providing precoding feedback by the terminal. The precoding matrices in the sub-sampled codebook are selected from a master codebook that is made-up of a long-term sub-codebook and a short-term sub-codebook. The definition defines a first subset of the long-term sub-codebook and a second subset of the short-term sub-codebook. A Multiple-Input Multiple-Output (MIMO) signal is received in the terminal via multiple receive antennas. Based on the received MIMO signal, a precoding matrix is selected from the sub-sampled codebook for precoding subsequent MIMO signals transmitted to the terminal. The precoding feedback indicating the selected precoding matrix is calculated.

  • Patent number: 9124327
    Abstract: A method for mobile telecommunication includes receiving in a mobile communication terminal downlink signals from at least first and second cells that coordinate transmission of the downlink signals with one another. Channel feedback is calculated in the terminal based on the received downlink signals. The channel feedback is configured to enable the first cell to precode a first signal destined for the terminal in response to the channel feedback with a first precoding vector, and to enable the second cell to precode a second signal destined for the terminal in response to the channel feedback with a second precoding vector that differs in magnitude from the first precoding vector. The first and second signals convey same data. The channel feedback is transmitted from the terminal. Calculating the channel feedback includes calculating one or more of a single-user Channel Quality Indicator (CQI), a multi-user CQI, and a non-cooperative-transmission CQI.

  • Patent number: 9048970
    Abstract: A method in a mobile communication terminal includes receiving signals from a serving cell and from one or more interfering cells. Respective channel responses are estimated in the terminal for the signals received from the interfering cells. A level of interference, caused by the signals of the interfering cells to a signal received from the serving cell, is derived from the channel responses. A Signal to Noise Ratio (SNR) is calculated for the signal received from the serving cell based on the level of interference caused by the signals of the interfering cells. Feedback information is produced based on the SNR and transmitted from the terminal.

  • Patent number: 8788918
    Abstract: A control channel encoder includes a determiner configured to determine a current value of K for encoding control signals of a length M, wherein K is a function of a code rate for a data channel. A table generator is configured to, if K is greater than a predetermined threshold, generate a repeated matrix from a fixed block encoding matrix by variably repeating rows from said fixed block encoding matrix. A puncturer is configured to, if K is less than the predetermined threshold, puncture the fixed block encoding matrix to reduce a size of the fixed block encoding matrix. A block encoder is configured to utilize said repeated matrix, to encode M input control bits as K encoded control bits, by generating an encoded payload from said repeated matrix.

    Abstract: A method for communication includes receiving in a receiver signals, which include one or more dedicated reference signals and are transmitted from a transmitter over a communication channel in multiple blocks. The signals in each block, including the dedicated reference signals, are transmitted on a respective group of subcarriers over a respective time interval and are precoded using a respective precoding scheme that maps the signals onto multiple antenna ports of the transmitter. One or more parameters of the communication channel are estimated over the dedicated reference signals included in two or more of the blocks whose respective precoding schemes do not differ from one another. The signals are decoded based on the estimated parameters.
