摘要： A method for communication includes providing a first transceiver configured to communicate with a second transceiver over a bi-directional link having a first aggregation of frequencies that are assigned to carry first communication traffic in a first link direction from the first transceiver to the second transceiver and a second aggregation of frequencies that are assigned to carry second communication traffic in a second link direction from the second transceiver to the first transceiver. Communication feedback is transmitted from the first transceiver to the second transceiver communication feedback at an adaptive feedback rate. The feedback rate is determined so as to achieve a desired balance between the information carrying capacities of the first and second aggregations. An information carrying capacity of the second aggregation is controlled responsively to the communication feedback.

摘要： A method includes receiving signals that are transmitted over a communication channel in multiple blocks that are transmitted in respective frequency bins during respective time intervals, some of the blocks in a predefined subset of the frequency bins containing reference signals. An estimate of the communication channel, for a given block transmitted during a respective time interval, is computed by (i) computing respective interim filtering results for the blocks transmitted in the respective time interval in the respective frequency bins belonging to the predefined subset, by filtering one or more of the reference signals transmitted in the respective frequency bins of the block; and (ii) combining the interim filtering results to produce the estimate of the communication channel.

摘要： A method in a receiver includes receiving from a transmitter an aggregated-spectrum signal including at least first and second component carriers in respective spectral bands. Information related to processing one or more of the component carriers is buffered in at least one shared buffer, such that storage locations in the shared buffer are selectably assignable for storing at least first information related to the processing of the first component carrier and second information related to the processing of the second component carrier. The one or more of the component carriers are processed in the receiver using the information buffered in the shared buffer.

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 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.
