    Abstract: An antenna (740) listens in each of a plurality of steerable sectors to determine if a primary beacon is present; transmits a primary device beacon in each of the plurality of steerable sectors if the primary beacon is not present; and transmits a secondary device beacon in a first one of the plurality of steerable sectors if a primary beacon is discovered. The antenna (740) may transmit the primary and secondary beacons on a different communication channel than a data communication channel or may transmit the primary and secondary beacons on a same communication channel as a data communication channel. The antenna (740) may divide the same communication channel into time slices wherein different time slices of a super-frame are utilized for the primary beacon, the secondary beacon, and the data communication. The secondary device (C, D) sends additional beacons in additional sectors if it receives non-primary beacon from the additional sectors.

    Abstract: A wireless network (300) operates with at least two different types of wireless devices, including Type-A wireless devices (320) that communicate using a first transmission scheme and Type-B wireless devices (310) that communicate using a second transmission scheme. Type-A wireless devices (320) can transmit Type-A beacons (325) using the first transmission scheme. Type-B wireless devices (310) can transmit and receive Type-B beacons (315) using the second transmission scheme. Type-B wireless devices (310) can also transmit Type-A beacons (325) using the first transmission scheme, but cannot receive the Type-A beacons (325). Before establishing communications in a new channel, a Type-B wireless device (310) performs power sensing to detect the presence of any non-Type-B wireless devices (200), and if such wireless devices (200) are detected, it switches to another channel. Otherwise, it transmits a Type-A beacon (325) and a Type-B beacon (315) to establish communications in the channel.

    Abstract: A method and apparatus discover hidden wireless devices in a wireless network using a directional antenna system, preventing partitioning of the wireless network. A first wireless device located in a first antenna sector is joined in response to an initial first beacon. First beacons are received from the joined first wireless device during corresponding first beacon periods. At least a second antenna sector is scanned during at least one first beacon period to listen for second beacons from a second wireless device in the second antenna sector, while remaining joined with the first wireless device. The first beacons are not received while the second antenna sector is scanned. The second wireless device is joined in response to an initial second beacon. Second beacons are then received from the joined second wireless device during corresponding second beacon periods, and the first beacons are received during the corresponding first beacon periods.

    Abstract: The current MBOA UWB MAC protocol requires a device that detects alien devices to include a BP Switch IE in its beacon so that its neighbors may learn the presence of the alien devices and follow that device to relocate their beacons in a coordinated fashion. However, during the transition period of beacon relocation, that device may decide to halt the relocation process as required by the standard and such decisions also have to be received by its neighbors. In such a case, a BP switch IE will be generated by that device which includes a BPST offset equal to a length of a superframe.

    Abstract translation: 目前的MBOA UWB MAC协议需要一种能够检测外来设备在其信标中包含BP交换机IE的设备,以便其邻居可以学习外来设备的存在并跟随该设备以协调的方式重新定位其信标。 然而,在信标重定位的过渡期间,该设备可以根据标准的要求决定停止重定位过程,并且这样的决定也必须由其邻居接收。 在这种情况下,BP开关IE将由该设备生成,该设备包括等于超帧长度的BPST偏移量。

    Abstract: A Single Carrier Block Transmission (SCBT) system employs an inherently parallel approach to error correction processing. At the transmission system (200), an incoming data stream is split (210) into P parallel data streams, each having a data rate equal to a fraction of the incoming data stream's data rate. The parallel data streams are then each separately encoded (220) in P parallel encoding processes (beneficially, using P parallel encoders (222)). The P separately encoded data streams are then merged (330), interleaved (320), and mapped (310) into a single stream of encoded symbols, which are transmitted to the receiver using an arbitrary modulation (240) and transmission scheme. At the receiver (255), the received data stream is de-interleaved (350) and split into P encoded data streams, which are then decoded (285) using P parallel decoders. Then, the decoded data streams are combined or multiplexed (295) into a single data stream.

    Abstract: A wireless device (100) communicates in a wireless system by selecting a communication channel (202) for communication, identifying a control channel or control channels (204) designated for communication of control information for the selected communication channel, and listening for the control information (212) on the control channel to determine if the selected communication channel is bonded with any other communication channel. When control information is received via the control channel(s) indicating that the selected communication channel is bonded with at least one other communication channel, then the wireless device abstains from communication on the selected communication channel, or communicates in a narrowband mode. When control information is received via the control channel(s) indicating that the selected communication channel is not bonded with another communication channel, or when no control information is received via the control channel, then the wireless device communicates via the selected communication channel.

    Abstract: A method enables a wireless device (310) to rendezvous with another wireless device (320) through a wireless network (330), where activation schedules of the wireless devices are not synchronized. The method includes determining a number of time units in each cycle of multiple communication cycles, identifying active time units in each cycle during which the first wireless device enters an active mode, and identifying inactive time units in each cycle during which the first wireless device enters an inactive mode. The sum of the active time units and the inactive time units equals the number of time units in each cycle. A first active time unit in each cycle occupies a same position in the cycle as an active time unit in a previous consecutive cycle. Also, a second active time unit in each cycle occupies a different position in the cycle than any active time unit in the previous consecutive cycle.
