    摘要： A method for communication includes, in a transmitter having a first number of transmit antenna ports, 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. A precoding operation maps the spatial layers onto the transmit antenna ports. A first upper limit is set when the precoding operation depends on feedback from the given receiver. A second upper limit, which does not exceed the first upper limit, is set when the precoding operation is not dependent on the feedback.

    摘要： A method for communication includes configuring a communication system that includes a transmitter (20) and a receiver with first precoding matrices for mapping up to N data streams onto N transmit antenna ports (52) of the transmitter. Each of at least some of the first precoding matrices are derived from respective second and third precoding matrices. The second and third precoding matrices are configured for mapping data onto respective numbers of transmit antenna ports that are less than N. The data streams are mapped onto the N transmit antenna ports using a precoding scheme based on one of the first precoding matrices. The mapped data streams are transmitted over the N transmit antenna ports from the transmitter to the receiver.

    摘要： A method for wireless communication includes receiving in a wireless communication terminal, which is configured to receive and transmit signals using one or more transceiver chains, an instruction from a base station to modify electrical power consumption of the wireless communication terminal. In response to the instruction, the electrical power consumption is modified by performing one or more of: (i) modifying a number of the transceiver chains that are active and (ii) modifying a clock rate in the wireless communication terminal.

    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 includes receiving a Multiple-Input Multiple Output (MIMO) signal over multiple communication channels from an antenna array (40) including a first set of antennas (44A...44D) having a first polarization and a second set of the antennas (48 A...48D) 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.
