Embodiments contemplate techniques for managing aggregation between using an anchor channel over a first frequency band as the anchor band between an Access Point and a wireless receiver/transmitter unit (WTRU). One or more embodiments may include the WRTU receiving one or more beacons via the anchor channel, where the one or more beacons may provide allocation information for allocating a supplementary channel on a second frequency band as a supplementary band that may be different from the first frequency band. Embodiments also contemplate establishing the supplementary channel over the supplementary band using the allocation information provided in the one or more beacons. Embodiments also contemplate exchanging data over the established supplementary channel on the supplementary band.
