摘要： A device (400) scans and classifies each channel within a spectrum of channels (215-270) as being occupied or unoccupied (255), and, if occupied, whether it is occupied by a primary user (240), a secondary user (230), or an unknown user (260). As a secondary device (400), transmissions are avoided on channels occupied by primary users (490). The device selectively joins an existing network of secondary devices, or establishes a new network on an unoccupied channel (125), based on the quality of service (QoS) that the channel can provide and/or other factors. If the device is paired with a target device (115), the paired device advertises itself on a selected channel (345-360) for a period that is at least as long as the time required to scan all channels, to facilitate discovery in the event that the target device is also in a search mode. The advertising duration randomly alternates (345) among integer multiples of the scan duration.
摘要翻译：设备（400）扫描频道频道（215-270）内的每个频道并将其分类为被占用或未被占用（255），并且如果被占用，是否它被主要用户占用（240），次要用户（230）或未知用户（260）。作为辅助设备（400），在主用户占用的信道上避免传输（490）。该设备基于信道可以提供的服务质量（QoS）和/或其他因素选择性地加入次要设备的现有网络，或者在未占用信道（125）上建立新网络。如果设备与目标设备（115）配对，则配对的设备在选定的信道（345-360）上宣告自己至少与扫描所有信道所需的时间一样长的时间段，以促进在目标设备也处于搜索模式的事件。广告持续时间在扫描持续时间的整数倍之间随机地交替（345）。

摘要： A detector module (100) is operable in a cognitive radio device and capable of determining channel occupancy. The detector module comprises a sensor (110) for sensing incumbent signals at a variable sensing threshold, wherein the sensor generates a first occupancy indication indicating whether the channel includes an incumbent signal having a sensing metric above the variable sensing threshold; a geo-location unit (120) for generating a second occupancy indication based on a location of the detector module; and a decision unit (130) for generating an occupancy decision based on both the first occupancy indication and the second occupancy indication.

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： A method and system for efficiently utilizing frequency spectrum resources is disclosed. The method comprises the steps of determining at least one spectrum opportunity (510), wherein the opportunity is identified by a frequency range and a time duration, determining a set of altered transmission characteristics (515, 517) to allow transmission of a desired signal in the identified frequency range, wherein the altered transmission characteristics avoid interference with signals expected in the frequency range, and transmitting said desired signal using the altered transmission characteristics when the transmission occurs during said time duration. In one aspect of the system, the step of determining at least one opportunity comprises the steps of receiving signals in known frequency ranges, and determining the characteristics of the received signals. The system comprises a receiving unit (1001) for receiving information items regarding at least one receivable signal, a processing unit (862) for determining characteristics of the at least one received signal, a managing unit (864) for altering transmission characteristics of a desired signal based on the determined received signal characteristics, wherein the altered transmission characteristics avoid interference with the received signals and a transmission unit (866) receiving said altered transmission characteristics to transmit said desired signal. In one aspect, the desired signal transmission characteristics are altered in a frequency range/time period to avoid interference with received signals in the frequency range.

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 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.
摘要翻译：通过在每个“家庭”频道上发送设备来定期访问其他“外部”频道来传播和收听这些频道上的广播信息，来提供在不同频道上操作的无线网络的分布式协调。在归属信道上发送的广播分组中的信息被分配的设备中继到外部信道上的设备，作为代表家庭信道中的其他设备操作的“代理设备”。在优选实施例中，优化该代理过程的各个方面以减少开销和延迟。每个通道被配置为将家用设备与外部设备区分开，以避免家庭和外部设备之间的争用。保留在外国频道上获取的信标插槽，以方便退回代理设备。在家庭通道，锚设备向其他设备通知代理设备暂时不存在，并在家庭通道上保留代理设备的信标时隙。
