Common Anchor Based Aggregation

1. A wireless transmit/receive unit (WTRU), the WTRU in communication with an access point (AP) via an anchor channel over a first frequency band, the first frequency band being an anchor band, the WTRU configured at least to: receive one or more beacons via the anchor channel, the one or more beacons providing operating information for a supplementary channel on a second frequency band, as a supplementary band, different from the first frequency band, at least a first beacon of the one or more beacons having a first structure and at least a second beacon of the one or more beacons having a second structure, the at least first beacon including control information for the anchor channel and the at least second beacon including control information for the supplementary channel; establish the supplementary channel over the supplementary band using the operating information; and exchange data over the established supplementary channel on the supplementary band.

2. The WTRU of claim 1 , wherein the receiving the one or more beacons via the anchor channel includes receiving a series of beacons, one or more of the series of beacons including control information for a respective series of supplementary channels.

3. The WTRU of claim 2 , wherein the series of beacons are periodically received from the AP.

4. The WTRU of claim 1 , wherein the operating information includes at least one of: a usage mode of the supplementary channel; activation or deactivation of the supplementary channel; an indication of whether the WTRU is scheduled for uplink or downlink transmission on the supplementary channel before a next beacon interval; an indication of whether the WTRU is restricted from using the supplementary channel for a current beacon interval; dynamic spectrum management information; a channel switch announcement; or a beacon interval number identifying a particular beacon interval.

5. The WTRU of claim 4 , wherein the dynamic spectrum management information includes at least one of: a quieting period during which the WTRU is restricted from transmitting over the supplementary channel; transmitted power limits for the supplementary channel; or coexistence information.

6. The WTRU of claim 1 , wherein the exchanging of the data over the established supplementary channel includes one of: sending the data over the established supplementary channel; receiving the data over the established supplementary channel; or sending and receiving data over the established supplementary channel.

7. The WTRU of claim 1 , wherein the at least first beacon is received at a first periodicity and the at least second beacon is received at a second periodicity.

8. The WTRU of claim 1 , wherein the anchor band is in an industrial, scientific, and medical (ISM) band and the supplementary band is in a television white space (TVWS) band.

9. The WTRU of claim 1 , wherein the operating information provides for an allocation of the supplementary channel as a downlink only channel, and communication via the supplementary channel is reserved for at least one of frames not requiring acknowledgement, broadcast frames, or multicast frames.

10. The WTRU of claim 1 , wherein the operating information provides for an allocation of the supplementary channel as an uplink only channel, and the WTRU is further configured to: send one or more reservations via the anchor channel for supplemental channel capacity; receive one or more assigned supplemental channel capacities in response to the one or more reservations; and send uplink data via the supplementary channel in one or more of the assigned supplemental channel capacities.

11. A method performed by a wireless transmit/receive unit (WTRU), the WTRU in communication with an access point (AP) via an anchor channel over a first frequency band, the first frequency band being an anchor band, the method comprising: receiving one or more beacons via the anchor channel, the one or more beacons providing operating information for a supplementary channel on a second frequency band, as a supplementary band, different from the first frequency band, at least a first beacon of the one or more beacons received at a first periodicity and at least a second beacon of the one or more beacons received at a second periodicity, the at least first beacon including control information for the anchor channel and the at least second beacon including control information for the supplementary channel; establishing the supplementary channel over the supplementary band using the operating information; and exchanging data over the established supplementary channel on the supplementary band.

12. An access point (AP), the AP in communication with a wireless transmit/receive unit (WTRU), via an anchor channel over a first frequency band, the first frequency band being an anchor band, the AP configured at least to: send one or more beacons via the anchor channel, the one or more beacons providing operating information for a supplementary channel on a secondary frequency band, as a supplementary band, different from the first frequency band, at least a first beacon of the one or more beacons being sent to a broadcast address and at least a second beacon of the one or more beacons being sent to a multicast address, the at least first beacon including control information for the anchor channel and the at least second beacon including control information for the supplementary channel; establish the supplementary channel over the supplementary band using the operating information; and exchange data over the established supplementary channel on the supplementary band.

13. The AP of claim 12 , wherein the sending of the one or more beacons via the anchor channel includes providing additional operating information for at least one additional supplementary channel on a further frequency band, as an additional supplementary band, different from the anchor or supplementary bands, the AP being further configured to: establish the additional supplementary channel over the additional supplementary band using the additional operating information provided by the one or more beacons; and exchange additional data over the additional supplementary channel on the additional supplementary band.

14. The AP of claim 13 , wherein the sending the one or more beacons via the anchor channel includes sending a first series of beacons and a second series of beacons, the first series of beacons including control information for the anchor channel and the second series of beacons including control information for the supplementary channel and the additional supplementary channel, wherein the AP being further configured to: determine whether to modify one or more channel allocations for exchanging data on the supplementary and the additional supplementary channels; insert into the second series of beacons, control information to allocate the supplementary channel as one of: an uplink only channel or a downlink only channel; and insert into the second series of beacons, control information to allocate the additional supplementary channel as one of: an uplink only channel or a downlink only channel.

15. The AP of claim 12 , wherein the AP being further configured to: send via the supplementary channel, frames including data; and receive via the anchor channel, a block acknowledgement for the frames received on the supplementary channel.
