摘要： 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. The values of the data bits carried by the multiple transmitted symbols are reconstructed responsively to the soft bit metrics.

摘要： 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.

摘要： 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.

摘要： A method for communication includes establishing a first connection between a wireless terminal and a base station of a long-range wireless data network, which operates in accordance with a first protocol that defines a sequence of time frames for transmission of data between the wireless terminal and the base station. A signal is sent from the wireless terminal to the base station identifying an interval including one or more of the time frames during which the wireless terminal will not receive data from the base station. During the interval, a second connection is established between the wireless terminal and an access point of a wireless local area network (WLAN) in accordance with a second protocol, different from the first protocol.

摘要： 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.

摘要： 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.
