Time-scheduled multichannel direct link
First Claim
1. In a wireless network comprising an access point wirelessly connected to a plurality of wireless devices, each of the wireless devices having a wireless direct link with at least one other wireless device, the method comprising:
- scheduling, at each of the wireless devices, a plurality of channel switches for the wireless device during a first interval based at least in part on channel scheduling information for the first interval;
wherein at least one channel switch includes a switch to a parallel channel to communicate information via a wireless direct link on the parallel channel for a first portion of the first interval.

Abstract
Disclosed herein are exemplary techniques for communicating information in a wireless system 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. The two or more wireless devices may switch to a parallel channel and use the established direct link to communicate information directly without the access point as an intermediary. Switching the wireless devices between a base channel and one or more parallel channels may be accomplished using one or more predetermined channel schedules.

29. In a wireless network, a wireless device comprising:
-
a transceiver; and
a direct link module operably connected to the transceiver and being adapted to;
receive channel scheduling information for a first interval;
tune the transceiver to a first channel for a first portion of the first interval;
communicate information with at least one other wireless device via a wireless direct link on the first channel during the first portion of the first interval; and
tune the transceiver to a second channel for a second portion of the first interval;
wherein a timing of the first portion of the first interval and a timing of the second portion of the first interval are based at least in part on the channel scheduling information. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. An access point wirelessly connected to a plurality of wireless devices, wherein each of the wireless devices has a wireless direct link with at least one other wireless device, the access point comprising:
-
a transceiver; and
a channel scheduling module operably connected to the transceiver and adapted to;
determine channel schedule information for the wireless direct links for a first interval, wherein the channel schedule information for a wireless direct link provides for at least one channel switch for the wireless devices associated with the wireless direct link during the first interval and where at least one of the channel switches includes a channel switch to a parallel channel to communicate information via the wireless direct link on the parallel channel for a first portion of the first interval; and
provide the channel schedule information to the wireless devices for scheduling one or more channel switches during the first interval via the transceiver. - View Dependent Claims (41, 42, 43, 44)
