Problems solved by technology

For example, streaming broadband video requires enormous amounts of bandwidth that will become increasingly difficult to provide using the limited RF spectrum resources typically allocated to wireless communication systems
In addition, more and more users are migrating to wireless communication systems for their communication services, which will increase the system load and further reduce the bandwidth available to any one user or to the shared system as a whole

Embodiment Construction

[0010] In general, various embodiments relate to improvements to wireless communication systems. In particular, some embodiments relate to techniques for improving utilization of the RF spectrum by multi-carrier communication systems. Examples of multi-carrier communication systems include, but are not limited to, systems conforming to various Institute of Electrical and Electronics Engineers (IEEE) standards, such as IEEE 802.11 for Wireless Local Area Networks (WLAN), IEEE 802 for Wireless Metropolitan Area Networks (WMAN). 16 standard, IEEE802.20 or Mobile Broadband Wireless Access (MBWA) and so on. For example, Worldwide Interoperability for Microwave Access (WiMAX) is a wireless broadband technology based on the IEEE802.16 standard. Under the IEEE802.16 standard, IEEE802.16-2004 and 802.16e amendments (802.16e-2005) are physical (PHY) layer specifications .

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.

Description

Background technique [0001] With the ever-increasing demand for mobile broadband data services and due to the lack of a large amount of contiguous radio frequency (RF) spectrum for deployment, next-generation broadband wireless access networks can be deployed using less RF spectrum resources. In addition, after the system is deployed, as the demand for higher data rates grows, the performance requirements for the broadband wireless access network will also increase. For example, streaming broadband video requires enormous amounts of bandwidth that will become increasingly difficult to provide using the limited RF spectrum resources typically allocated to wireless communication systems. Furthermore, more and more users are migrating to wireless communication systems for their communication services, which will increase the system load and further reduce the bandwidth available to any one user or to the entire shared system. Thus, there is a need to improve the performance of w...
