  • Patent number: 9265004
    Abstract: A method for communication in a receiver (20) includes receiving over a wireless communication channel a signal that carries at least a control channel. A first estimate of a response of the wireless communication channel is computed using a first estimation process having a first latency, and the control channel is decoded based on the first estimate. Upon identifying, based on the decoded control channel, a time period during which no data channel is to be addressed to the receiver, circuitry (24) of the receiver is shut down for at least part of the identified time period. A second estimate of the response is computed using a second estimation process having a second latency, higher than the first latency, and a data channel that is addressed to the receiver is decoded based on the second estimate.

  • Patent number: 9258833
    Abstract: A method for communication in a wireless device (24) includes establishing a first connection with a base station (BS-28) of a long-range wireless data network, and a second connection on a Wireless Local Area Network (WLAN). A time interval (96) is selected in the wireless device for communicating over the second connection. In preparation for the selected time interval, the BS is caused to refrain from scheduling data transmission from the wireless device to the BS over the first connection during the time interval, by reporting to the BS prior to the time interval that no data is pending for transmission from the wireless device. The wireless device communicates over the second connection on the WLAN during the time interval.

    Abstract: A method for communication includes communicating between one or more first base stations (28A) and first wireless communication terminals (32A) using a first alternating pattern (56) of downlink time intervals and uplink time intervals. A time offset is selected between the first alternating pattern and a second alternating pattern (60), which is used by one or more second base stations (28B) for communicating with second wireless communication terminals (32B), so as to minimize impact of interference between the first and second wireless communication terminals. The first base stations are synchronized relative to the second base stations according to the selected time offset.

  • Patent number: 9170816
    Abstract: A processor includes one or more processing units, an execution pipeline and control circuitry. The execution pipeline includes at least first and second pipeline stages that are cascaded so that program instructions, specifying operations to be performed by the processing units in successive cycles of the pipeline, are fetched from a memory by the first pipeline stage and conveyed to the second pipeline stage, which causes the processing units to perform the specified operations. The control circuitry is coupled, upon determining that a program instruction that is present in the second pipeline stage in a first cycle of the pipeline is to be executed again in a subsequent cycle of the pipeline, to cause the execution pipeline to reuse the program instruction in one of the pipeline stages without re-fetching the program instruction from the memory.

  • Patent number: 9036569
    Abstract: A method for communication includes allocating, in a multiple-access communication system (20) that uses multiple subcarriers, first subcarriers to a first communication terminal for transmitting first data, and second subcarriers to a second communication terminal for transmitting second data. The first communication terminal is assigned to modulate the first data onto at least some of the first subcarriers using a first multi-carrier modulation scheme, to produce a first signal. The second communication terminal is assigned to modulate the second data onto at least some of the second subcarriers using a second multi-carrier modulation scheme, which has a reduced peak-to-average power ratio (PAPR) relative to the first multi-carrier modulation scheme, to produce a second signal. Simultaneous communication is carried out with the first and second communication terminals by simultaneously receiving the first and second signals over the first and second subcarriers.

  • Patent number: 8462746
    Abstract: A terminal (24) for use in a wireless network (20) includes a radio frequency (RF) receiver (30), which is configured to receive and downconvert a RF signal. The RF signal includes downlink frames, each downlink frame including at least an allocation zone followed by a data zone. The allocation zone contains an indication of a time allocation in the data zone during which downlink data will be transmitted to the terminal. An analog/digital (A/D) converter (36) converts the output signal from the RF receiver into a stream of digital samples. A digital processing circuit (40, 52, 54, 56) processes the digital samples so as to identify the time allocation and to recover the downlink data transmitted during the identified time allocation, while shutting down the RF receiver during at least one interval during the downlink frame that is outside the identified time allocation.

A maximum number of the subcarriers on which the transmitter may transmit the data simultaneously without violating a predetermined signal power criterion is calculated. The transmitter is allocated a time-frequency allocation containing the maximum number of the subcarriers. The data is transmitted from the transmitter to the receiver using the allocated time-frequency allocation.

  • Patent number: 8194801
    Abstract: A method for communication includes receiving a spatially-multiplexed signal using multiple receivers to produce multiple respective received signals. The spatially-multiplexed signal includes multiple simultaneously-transmitted symbols, which are selected from respective sets of constellation symbols, each constellation symbol representing a respective set of values of a group of data bits. Combinations of the constellation symbols are traversed iteratively. Each combination includes one constellation symbol from each of the sets of the constellation symbols and represents N data bits. The traversed combinations are searched for a combination that matches the received signals. During traversal of the combinations, at least 2N measures of likelihood regarding the values of the data bits represented by each traversed combination are accumulated. The accumulated measures of likelihood are processed to produce soft bit metrics.

  • Patent number: 8165168
    Abstract: A communication terminal includes a Radio Frequency (RF) unit and a baseband processor. The RF unit is operative to receive signals from a Base Station (BS) of a wireless communication network using a communication protocol that defines time frames divided in a time domain into zones. Each zone corresponds to a respective communication mode between the BS and the terminal and occupies respective time intervals within the frames. The baseband processor is coupled to receive from the BS via the RF unit synchronization information indicating whether the time intervals allocated to at least a given zone by the BS and by at least one other BS of the wireless communication network are synchronized with one another, and to process the signals received from the BS so as to cancel, responsively to the synchronization information, interference caused to the signals by the at least one other BS.

  • Patent number: 8160001
    Abstract: A communication method includes establishing a first communication session over a first connection between a wireless terminal and a base station (BS) of a long-range wireless data network, which operates in accordance with a first protocol that defines a sequence of time frames. Based on the time frames defined by the BS, time slots are allocated for establishing a second communication session over a second connection between the wireless terminal and a peripheral wireless device, which operates in accordance with a second, short-range time-slotted communication protocol different from the first protocol. Time intervals are allocated within the time frames for communication between the BS and the wireless terminal over the first connection, such that the allocated time intervals are interleaved with and do not overlap the allocated time slots. The first and second communication sessions are concurrently conducted in the allocated time intervals and the assigned time slots, respectively.
