    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.
