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 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, 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 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.

摘要： A user device on a wireless network includes a receiver, a noise detector and a noise determiner. The receiver receives downlink data communications from a base station that indicates an allocation of time/frequency resource blocks at least to user devices that are communicating with the base station. The noise detector measures noise in a time/frequency resource block, comprising plural time/frequency bins, that is not allocated to one of the user devices. The noise determiner determines a level of interfering noise based on noise in the resource block that is not allocated to one of the user devices.

摘要： A method for a user equipment device includes receiving a reference signal from a desired transmitter and obtaining information about other, interfering transmitters whose signals are receivable by the user equipment. The information includes a reference signal sequence of reference signals transmitted by the other transmitters. The method also includes modeling interference caused by the reference signals of the other transmitters on the received reference signal when determining a channel estimate for a channel between the user equipment device and the desired transmitter.
