Neighbor discovery in a wireless system
First Claim
1. A method of providing beacons by an access point, comprising:
- cooperating, with at least one other access point, to determine when to transmit beacons of associated time division multiplexed wireless networks, wherein each beacon comprises an identifier of one of the time division multiplexed wireless networks;
maintaining at least one defined spacing between successive transmissions of the beacons; and
transmitting the beacons of at least one of the networks.

Abstract
Beacons may be grouped to facilitate neighbor discovery in a wireless network. For example, neighboring access devices such as IEEE 802.11 access points may cooperate to transmit beacons in a group. In this way, a wireless device seeking to discover the neighboring access devices may scan for the beacons for a shorter period of time. An indication may be provided to enable a wireless device to more efficiently scan the beacons. For example, the indication may indicate the channel the wireless device should scan to receive the next beacon that is to be transmitted. In addition, the indication may include information relating to the transmission time of the next beacon. Other aspects, embodiments, and features are also claimed and described.
