Re-configurable communication device and managing method thereof

Abstract

A communication apparatus including a physical information recognizing module, an MAC information recognizing module, a coordinating module, and a re-configurable transmitting / receiving module is provided. The physical information recognizing module recognizes a set of physical information relative to at least one communication network. The MAC information recognizing module recognizes a set of MAC information relative to the at least one communication network. The coordinating module generates a set of control signals selectively based on the set of physical information and the set of MAC information. The re-configurable transmitting / receiving module is configured according to the set of control signals and is used for transmitting / receiving data via the at least one communication network.

Description

[0001]This application claim the benefit of U.S. Provisional Application No. 60 / 913,298, filed on Apr. 23, 2007, for which priority is claimed under 35 U.S.C. § 120, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is related to mobile equipment with re-configurable transceiver and, in particular, to cognitive radio.[0004]2. Description of the Prior Art[0005]From mid-1980's, many researchers have hoped to realize a universal wireless communication system with 3 G communication techniques. However, in the past years, the universal wireless communication system is not realized. Further, to conform to different requirements (such as different data rates and different propagation distances) of actual applications, various new wireless communication standards have also been widely deployed in addition to 3G systems. Among so many wireless communication standards, some standards may co-e...

AI Technical Summary

Benefits of technology

"The invention is about a communication device that can adapt to and efficiently use co-existing networks. It uses information about the physical and MAC (Mobile Access Layer) characteristics of the network to generate control signals and re-configure the device for optimal data transmission and reception. This allows the device to make the best use of available network resources and improve overall networking efficiency for mobile devices in front of co-existing networks."

Problems solved by technology

However, in the past years, the universal wireless communication system is not realized.

Although there are diverse standards, regulatory institutions in several countries found that most of the radio frequency spectrum was inefficiently utilized.

For spectrum sensing cognitive radio, maintaining seamless communication and determining a fair spectrum schedule are both important issues.
