Abstract:
1. A method for performing peer-to-peer wireless communication between a first station (STA) and a second STA, the method comprising: the first STA establishing a direct link setup (DLS) link with the second STA for performing peer-to-peer communication with the second STA on a basic service set (BSS) channel, which is shared by all stations and an access point (AP) in a BSS; the first STA negotiating directly with the second STA through the DLS link established on the BSS channel for switching a channel for the DLS link to a DLS channel which is different from the BSS channel; and the first STA performing peer-to-peer communication with the second STA on the DLS channel, wherein the first STA switches back and forth between the DLS channel and the BSS channel in accordance with an agreed synchronization schedule for maintaining connectivity with an access point (AP) while performing peer-to-peer communication on the DLS channel.
