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.

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.
A station (STA) configured to support peer-to-peer wireless communication, the STA comprising:
- a transceiver;
- and
- a controller configured to establish a direct link setup (DLS) link with a second STA for performing peer-to-peer communication with the second STA on a basic service set (BSS) channel, which is used by all stations and an access point (AP) in a BSS, negotiate directly with the second STA through the DLS link on the BSS channel for switching a channel for the DLS link to a DLS channel which is different from a BSS channel and switch 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.
