Abstract

Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.

First claim

The invention claimed is:

1. A method for use in an IEEE 802.11 access point (AP) capable of receiving a plurality of radio frequency (RF) bands, each band including a respective plurality of channels, the method comprising:
transmitting a first IEEE 802.11 beacon via at least one channel in a first RF band for reception by an IEEE 802.11 wireless transmit/receive unit (WTRU);
transmitting a second IEEE 802.11 beacon for reception by the IEEE 802.11 WTRU via a second channel in a second RF band based on a beacon interval, corresponding to the second RF band, that is indicated by the first IEEE 802.11 beacon;
wherein the second IEEE 802.11 beacon is transmitted directionally on the second RF band;
wherein the second RF band comprises a 60 gigahertz frequency; and
wherein the first RF band does not comprise the 60 gigahertz frequency.

2. The method of claim 1 , wherein the IEEE 802.11 WTRU is configured to scan multiple channels simultaneously.

3. The method of claim 1 , further comprising:
performing an association procedure based on information transmitted in the second IEEE 802.11 beacon.

4. The method of claim 1 , wherein the first IEEE 802.11 beacon includes a network identification.

5. The method of claim 1 , wherein the first IEEE 802.11 beacon includes a network type identification.

6. The method of claim 1 , wherein the second IEEE 802.11 beacon includes a sector number.

7. An IEEE 802.11 wireless access point (AP) capable of transmitting a plurality of radio frequency (RF) bands, each band including a respective plurality of channels, the AP comprising:
a transmitter configured to transmit a first IEEE 802.11 beacon via at least one channel in a first RF band for reception by an IEEE 802.11 wireless transmit/receive unit (WTRU), and to transmit a second IEEE 802.11 beacon for reception by the IEEE 802.11 WTRU via a second channel in a second RF band based on a beacon interval, corresponding to the second RF band, that is indicated by the first IEEE 802.11 beacon;
wherein the second IEEE 802.11 beacon is transmitted directionally on the second RF band;
wherein the second RF band comprises a 60 gigahertz RF band; and
wherein the first RF band does not comprise the 60 gigahertz RF band.

8. The AP of claim 7 , wherein the IEEE 802.11 WTRU is configured to scan multiple channels simultaneously.

9. The AP of claim 7 , further comprising:
a processor configured to perform an association procedure based on information transmitted in the second IEEE 802.11 beacon.

10. The AP of claim 7 , wherein the first IEEE 802.11 beacon includes a network identification.

11. The AP of claim 7 , wherein the first IEEE 802.11 beacon includes a network type identification.

12. The AP of claim 7 , wherein the second IEEE 802.11 beacon includes a sector number.
