Abstract:
1. A method for performing peer-to-peer wireless communication between a first station (STA) and a second STA in a basic service set (BSS), the method comprising: the first STA establishing a direct link with the second STA on a first channel, wherein messages for setting up the direct link are exchanged between the first STA and the second STA through an access point (AP) of the BSS, wherein both the first STA and the second STA are associated with the AP; the first STA negotiating with the second STA to switch the direct link to a second channel, wherein messages for switching the direct link to the second channel are exchanged directly between the first STA and the second STA via the direct link on the first channel without being relayed through the AP; and the first STA exchanging data with the second STA via the direct link on the second channel, wherein the first STA switches back and forth between the first channel and the second channel in accordance with a schedule agreed with the second STA for maintaining connectivity with the AP while performing peer-to-peer communication on the second channel.
