1. A method comprising:
- transmitting, via a transmitter and 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;
transmitting, via the transmitter and on a second channel of the wireless medium and without scanning the second channel for wireless devices, a second frame inviting a wireless device operating off the first channel to join the peer-to-peer group on the first channel;
receiving, via a receiver and on the second channel of the wireless medium, 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
returning, responsive to receiving the third frame via the receiver and prior to the duration of time expiring, to the first channel of the wireless medium effective to enable a next attempt of the member device to successfully access the wireless medium subsequent the expiration of the duration of time.

14. A system-on-chip (SoC) comprising:
-
a transmitter configured to transmit via a wireless medium; a receiver configured to receive via the wireless medium; and a peer-to-peer manager configured to; transmit, via the transmitter, a first frame effective to prevent a member device of a peer-to-peer group operating on a first channel of the wireless medium from attempting to access the wireless medium for a duration of time; transmit, via the transmitter and without scanning a second channel of the wireless medium for wireless devices, a second frame inviting a wireless device operating off the first channel to join the peer-to-peer group on the first channel; receive, via the receiver and 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 enable, responsive to receiving the third frame and prior to the duration of time expiring, the transmitter and the receiver to communicate on the first channel of the wireless medium effective to grant a next attempt of the member device to successfully access the wireless medium subsequent the expiration of the duration of time. - View Dependent Claims (15, 16, 17, 18, 19, 20)
