摘要： A wireless device (A) in a first antenna sector (40) is discovered using a directional antenna (322), which sends and receives signals in multiple antenna sectors. Multiple primary beacons are transmitted in corresponding primary beacon time slots (1P-4P), which correspond to the antenna sectors (10-40) and have associated secondary beacon time slots (1s-4s). A secondary beacon is received from the wireless device in a first secondary beacon time slot (4sA) associated with a first primary beacon time slot (4P) corresponding to the first sector, the secondary beacon being responsive to a first primary beacon included in the first primary beacon time slot. An additional first secondary beacon time slot (4s) is added in association with the first primary beacon time slot. The additional first secondary beacon time slot enables an additional wireless device in the first sector to send an additional secondary beacon in response to a subsequent first primary beacon included in the first primary beacon time slot.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and wireless device merge multiple unsynchronized beacon groups in a wireless network, each beacon group including at least one wireless device. A first beacon is received from at least one first wireless device in a first beacon group (S514), the first wireless device having a first directional antenna. A second beacon is received from at least one second wireless device in a second beacon group that is not synchronized with the first beacon group (S516), the second wireless device having a second directional antenna. A first response beacon is relocated (S520) and sent (S522) to the first wireless device in the first beacon group. The relocated first response beacon instructs the first wireless device to relocate the first beacon. Accordingly, the second beacon, the relocated first response beacon, and the relocated first beacon are synchronized.
