System and method for establishing a direct link on the high throughput channel of a multi-rate channel wireless communications network

摘要

A system and method for wireless communication over multi-rate channels are disclosed. One embodiment of the system includes a first wireless device; a second wireless device; and an access point that can communicate over high-rate and low-rate channels. One or more of the first and second wireless devices and the access point can include neighbor information on the wireless stations in the wireless network. One or more of the first and second wireless devices and the access point may be configured to transmit a frame in an attempt to establish a direct link over the first channel between the first and second stations. Before transmitting the frame, the one or more of the first and second wireless devices and the access point may determine whether a direct link can be established over the first channel between the first and second stations, based at least partly on the neighbor information. This scheme can significantly reduce time wasted for unsuccessful direct link setup attempts for the high-rate channel transmissions.
