Abstract
Disclosed herein are exemplary techniques for the communication of information in a wireless system by using multiple wireless channels. A direct link between two or more wireless devices may be established by performing a direct link setup between two or more wireless devices using an access point, where the direct link setup is conducted over a base channel and the direct link is established on a parallel channel. The two or more wireless devices may switch to the parallel channel and use the established direct link to communicate information directly without the access point as an intermediary. In anticipation of a predetermined event, such as the transmission of a delivery traffic indication map (DTIM) beacon frame by the access point, the two or more wireless devices may switch back to the base channel so that uplink, downlink and/or peer-to-peer information may be transmitted and/or received.
