摘要： 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.

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 method for communication includes accepting a request from a transmitter (48) to transmit data to a receiver (56) in a multiple-access communication system that uses multiple subcarriers. 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.

摘要： 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.

摘要： A method for communication includes establishing a first connection between a wireless terminal (22) and a base station (26) of a long-range wireless data network, which operates in accordance with a first protocol that defines a sequence of time frames (120) 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 (24) 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.
