1. A wireless communication device, comprising:
- a processor to perform carrier aggregation of multiple wireless carriers to provide variable bandwidth for a multicarrier wireless communications system comprising an orthogonal frequency division multiple access (OFDMA) system, each of the aggregated wireless carriers to utilize a different portion of radio frequency spectrum, with a number of the aggregated wireless carriers to increase or decrease based on an amount of bandwidth needed by a client device, the aggregated wireless carriers to include a primary wireless carrier and a secondary wireless carrier, the secondary wireless carrier to differ from the primary wireless carrier with respect to one or more communication parameters comprising at least one of amount of channel bandwidth and duplexing mode; and
a wireless transceiver to communicate information over the aggregated wireless carriers using orthogonal frequency division multiplexing symbols.

Abstract
Multicarrier techniques for wireless communications system are described. An apparatus may comprise a carrier management module to define a primary carrier for use by a multicarrier communications system to communicate control information, and a secondary carrier for use by the multicarrier communications system to communicate media information, with the secondary carrier having a communication parameter and technology that is potentially different from the primary carrier. Other embodiments are described and claimed.
