摘要： A distributed coordination of a wireless network operating on different channels is provided by dispatching a device on each 'home' channel to regularly visit other 'foreign' channels to propagate and listen to broadcast information on these channels. The information in the broadcast packets transmitted on the home channel is relayed to the devices on the foreign channels by the dispatched device, as a 'proxy device' that operates on behalf of the other devices in the home channel. In a preferred embodiment, various aspects of this proxy process are optimized to reduce overhead and delays. Each channel is configured to distinguish home devices from foreign devices, to avoid contention between home and foreign devices. Acquired beacon slots on foreign channels are reserved to facilitate returning proxy devices. At the home channel, an anchor device alerts other devices of the proxy device's temporary absence and preserves the proxy device's beacon slot on the home channel.

摘要： Self-coexistence of first and second wireless communication networks (200) is improved by transmitting a coexistence beacon from a first station (210, 220) of the first wireless communication network (200) to a first station (210, 220) of the second wireless communication network (200). The coexistence beacon includes information about a traffic reservation of the first station (210, 220) of the first wireless communication network (200). The first station (210, 220) of the second wireless communication network (200) may then use this information in a variety of ways to reduce data collisions between the two networks (200). It can communicate this information to a base station (210) of the second wireless communication network (200). The base station (210) of the second wireless communication network (200) can then use this information to more efficiently allocate frequency channels and/or time slots for future traffic reservations of the first station (220) of the second wireless communication network (200).

摘要： In a wireless communication network (200) comprising a base station (210) and a plurality of remote terminals (220), the plurality of remote terminals (220) are divided into a plurality of clusters (230) for communication with the base station (210), and each of the remote terminals (220) is assigned to a cluster (230) based on at least one characteristic, measured by one or more of the remote terminals (220), of one or more external signals transmitted by one or more external terrestrial transmitters (250) not associated with the communication network (200). Accordingly: a parameter of a communication between the base station (210) and each remote terminal (220) may be selected according to the cluster (230) to which each remote terminal (220) belongs; remote terminals (220) within a cluster (230) may be enabled to communicate directly with each other; and/or remote terminals (220) may be selected to perform frequency spectrum profile measurements of the frequency band used by the communication network (200) according to the clusters (230) to which they are assigned.

摘要： A system includes a first primary wireless system (120) that communicates over a first range, and a first beaconing device (130) associated with the first primary wireless system (120). The first beaconing device (130) communicates over at least at a second range, wherein the second range is greater than the first range. The first beaconing device listens for beacons (510) from other beaconing devices (130) associated with other primary wireless systems (120) on a plurality of channels over which the other primary systems may operate. After listening for beacons from the other beaconing devices (130) associated with other primary wireless systems, the first beaconing device transmits a first beacon (510) to a wireless device (114) of a secondary wireless system (110) that may communicate over the second range. The first beacon includes data indicating an occupation of a first one of the channels by the first primary wireless system (120).
