    摘要: Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.

    摘要: A dynamic spectrum management (DSM) system includes a plurality of stations and a central entity. A plurality of different radio access technologies are deployed in the DSM system and the central entity coordinates and manages wireless communications in the network. A direct link station receives a beacon periodically from an access point (AP). The direct link station may receive a direct link synchronization message from the AP indicating that a following target beacon transmission time (TBTT) is a synchronization TBTT (STBTT). The direct link station may silence the direct link channels during the STBTT. The direct link station may perform carrier sense multiple access (CSMA) on a primary channel of the direct link to get an access to all direct link channels. A connectivity map procedure may be performed to establish a map for connectivity, services, or capabilities of the devices in the network.
