1. A method comprising:
- transmitting, via a wireless interface configured to communicate on a first channel of a wireless medium, a first frame effective to prevent a member device of a peer-to-peer group operating on the first channel from attempting to access the wireless medium for a duration of time;
configuring the wireless interface to communicate on a second channel of the wireless medium;
transmitting, via the wireless interface configured to communicate on the second channel, a second frame inviting a wireless device operating off-channel to join the peer-to-peer group on the first channel;
receiving, via the wireless interface configured to communicate on the second channel, a third frame from the wireless device indicating that the wireless device will join the peer-to-peer group on the first channel of the wireless medium; and
configuring the wireless interface to communicate on the first channel of the wireless medium before or when the duration of time expires effective to grant a next attempt of the member device to access the wireless medium subsequent the expiration of the duration of time.

Abstract
A wireless medium often supports communications of multiple devices on different respective channels of the wireless medium. In some aspects described herein, a first frame is transmitted on a first channel of a wireless medium effective to prevent a member device of a peer-to-peer group from attempting to access the wireless medium, a second frame inviting a wireless device to join the peer-to-peer group is transmitted on a second channel of the wireless medium, and the first channel of the wireless medium is returned to thereby enabling a next attempt of the member device to access the wireless medium.

7. One or more computer-readable storage devices comprising processor-executable instructions that, responsive to execution by a processor, implement a peer-to-peer manager to:
-
transmit, via a wireless interface configured to communicate on a first channel of a wireless medium, a first frame effective to prevent a member device of a peer-to-peer group operating on the first channel from attempting to access the wireless medium for a duration of time; configure the wireless interface to communicate on a second channel of the wireless medium; transmit, via the wireless interface configured to communicate on the second channel and without scanning the second channel for wireless devices, a second frame inviting a wireless device operating off-channel to join the peer-to-peer group on the first channel; receive, via the wireless interface configured to communicate on the second channel, a third frame from the wireless device indicating that the wireless device will join the peer-to-peer group on the first channel of the wireless medium; and configure the wireless interface to communicate on the first channel of the wireless medium before or when the duration of time expires effective to grant a next attempt of the member device to access the wireless medium subsequent the expiration of the duration of time. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus comprising:
-
a wireless interface to communicate via a wireless medium; and a peer-to-peer manager to perform operations comprising; transmitting, via the wireless interface and on a first channel of the wireless medium, a first frame effective to prevent a legacy device of a peer-to-peer group from attempting to access the wireless medium for a duration of time, the legacy device not capable of understanding peer-to-peer networking communications; configuring the wireless interface to communicate on a second channel of the wireless medium; transmitting, via the wireless interface and on the second channel, a second frame inviting a wireless device operating off-channel to join the peer-to-peer group on the first channel; configuring the wireless interface to communicate on a third channel of the wireless medium; transmitting, via the wireless interface and on the third channel, a third frame inviting another wireless device operating off-channel to join the peer-to-peer group on the first channel; and configuring the wireless interface to communicate on the first channel of the wireless medium before or when the duration of time expires effective to enable the legacy device to access the wireless medium subsequent the expiration of the duration of time. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
