Embodiment

[0328] CLAIMS 1. A method for direct link operation in a wireless communication network comprising a central entity and a plurality of stations.

[0329] 2. The method of embodiment 1, wherein a plurality of different radio access technologies are deployed in the network, and a central entity coordinates and manages wireless communications in the network.

[0330] 3. The method as in any one of embodiments 1-2, comprising the direct link station periodically receiving beacon messages from the AP on the first set of channels.

[0331] 4. The method of embodiment 3, wherein the direct link station has a direct link for communicating with a peer direct link station on the second set of channels.

[0332] 5. The method of any one of embodiments 3-4, wherein the beacon message is received on a first channel based on TBTT, the first set of channels and the second set of channels each comprising at least one channel.

[0333] 6. The method of any one of embodiments 3-5, further comp...

Abstract

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

[0001] Cross References to Related Applications [0002] This application claims Serial Nos. 61 / 414,125 filed November 16, 2010, 61 / 429,269 filed January 3, 2011, 61 / 439,241 filed February 3, 2011, and February 3, 2011 US Provisional Patent Application No. 61 / 439,251, filed March 22, 2011, and US Provisional Patent Application No. 61 / 466,235, filed March 22, 2011, the contents of each of which are hereby incorporated by reference. Background technique [0003] A wireless communication environment in a home or office typically includes several independently developed radio access technologies and standards. These techniques were originally designed for the target applications, and they have performed relatively well for these applications. In a typical home or office environment, access to content (eg, web pages, video, etc.) is provided to a broadband modem through the home owner's IP backhaul connection. This connection is typically via Digital Subscriber Line (DSL), cable,...
