摘要： A method for communication includes receiving in a receiver (70) signals, which include one or more dedicated reference signals (98), that are transmitted from a transmitter (20) over a communication channel in multiple blocks. The signals in each block, including the dedicated reference signals, are transmitted on a respective group of sub carriers over a respective time interval and are precoded using a respective precoding scheme that maps the signals onto multiple antenna ports (52) of the transmitter. Based on the received signals, feedback is computed in the receiver with respect to the communication channel in each of multiple spectral sub-bands, and the feedback for the multiple spectral sub-bands is reported to the transmitter.

摘要： A method includes, in a mobile communication terminal, receiving from at least first and second base stations, which cooperate in a coordinated transmission scheme, signals that are transmitted over respective first and second communication channels. Respective channel measures are calculated for the communication channels based on the received signals. First and second feedback data, which are indicative of the respective channel measures of the first and second communication channels, are formulated such that the first feedback data has a first data size and the second feedback data has a second data size, different from the first data size. The first and second feedback data are transmitted from the mobile communication terminal to at least one of the base stations.

摘要： A method includes receiving in a mobile communication terminal (24) downlink signals from at least first and second cells (28) 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 cause the first cell to precode subsequent downlink signals in response to the channel feedback with a first precoding vector, and to cause the second cell to precode the subsequent downlink signals in response to the channel feedback with a second precoding vector that differs in magnitude from the first precoding vector. The channel feedback is transmitted from the terminal.

摘要： A method for communication includes receiving in a receiver (70) signals, which include one or more dedicated reference signals (98) and are transmitted from a transmitter (20) over a communication channel in multiple blocks (9OA, 90B). 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 (52) of the transmitter. Two or more of the blocks whose respective precoding schemes differ from one another by no more than a predefined distance are identified. One or more parameters of the communication channel are estimated over the dedicated reference signals included in the identified blocks. The signals are decoded based on the estimated parameters.

摘要： A method includes receiving a Multiple-Input Multiple Output (MIMO) signal over multiple communication channels from an antenna array including a first set of antennas having a first polarization and a second set of the antennas having a second polarization that is orthogonal to the first polarization. First feedback information is calculated relating to first interrelations between the antennas within either the first set or the second set. Second feedback information is calculated relating at least to second interrelations between the first set and the second set of the antennas. The first feedback information is transmitted at a first time/frequency granularity, and the second feedback information is transmitted at a second time/frequency granularity that is finer than the first time/frequency granularity.

摘要： A method for communication includes, in a transmitter (20) having a first number of transmit antenna ports (52), setting an upper limit on a second number of spatial layers to be used by the transmitter to be less than the first number. An actual number of the spatial layers, which does not exceed the upper limit, is allocated for transmission to a given receiver. One or more streams of modulated symbols are mapped onto the allocated actual number of the spatial layers. The actual number of the spatial layers are transmitted from the transmitter to the given receiver.
