Method and system for performing peer-to-peer communication between stations within a basic service set
First Claim
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.

Abstract
A method and system for performing peer-to-peer wireless communication between stations (STAs) within a basic service set (BSS) while maintaining connectivity with an access point (AP) in the BSS are disclosed. A source STA, an AP and a destination STA negotiate a direct link setup (DLS) channel for performing peer-to-peer communication between the source STA and the destination STA. The DLS channel may be different from a BSS channel used for communication between the AP and each of the STAs. The source STA and the destination STA then perform peer-to-peer communication on the negotiated DLS channel.

7. A station (STA) for performing peer-to-peer wireless communication with a peer STA in a basic service set (BSS), the STA comprising:
a transceiver configured to transmit a first message to an access point (AP) to establish a direct link with a peer STA on a first channel, to transmit a second message to the peer STA via the direct link on the first channel to negotiate with the peer STA to switch the direct link to a second channel, to exchange data with the peer STA via the direct link on the second channel, and to switch back and forth between the first channel and the second channel in accordance with a schedule agreed with the peer STA for maintaining connectivity with the AP while performing peer-to-peer communication on the second channel. - View Dependent Claims (8, 9, 10, 11, 12)
