Event-based multichannel direct link

摘要

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.

id="REI-00004" date="20141028" 1. In an 802.11x wireless network comprising an access point logically connected to at least a first wireless device and a second wireless device, a method of establishing a point-to-point connection directly between the first and second wireless devices comprising:
sending a setup request frame from the first wireless device to the second wireless device on a first communication channel via the access point, the setup request frame including a proposed second communication channel; sending a setup response frame from the second wireless device to the first wireless device on the first communication channel via the access point; and communicating information directly between the first and second wireless devices on the second communication channel for a first time period.
