Foreword Th

19、is Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS). Introduction The present document provides a feasibility study on reconfigurable radio systems which are capable to use technological elements known as Cognitive Radio. An overall and harmonize

20、d technical concept for future Cognitive Radio Systems is outlined. There are several factors driving the future evolution of radio technologies and network architectures towards more flexible and reconfigurable Cognitive Radio Systems: Increasing growth of mobile traffic in terms of subscribers, da

21、ta volumes and data rates There are more than 3 billion mobile phone users today. There are estimations (e.g. by WWRF) that by 2017 there will be 7 trillion wireless devices serving 7 billion users. To meet these expectations with the limited amount of radio spectrum, more flexible ways to exploit t

22、he radio frequencies among multiple services and radio networks are needed. Multitude of standards, Composite wireless networks and multiradio terminals Many communication applications, which originated as tightly-coupled with specific radio technologies, would benefit from decoupling the applicatio

23、n from the radio platform. At the same time network operators are building composite wireless networks to provide access to multiple services. When a multiradio terminal is having multiple applications simultaneously active, there is a need to coordinate the operations of the different radios in ord

24、er to reach the cost and energy efficient use of overall radio communications capacity. Regulators are starting to consider the extension of the possibility to allow secondary access to some frequency bands, increasing spectrum utilization In order to meet the increasing data traffic volumes regulat

25、ors have started to consider the extension of the possibility to allow wireless data devices to operate as secondary users on spectrum bands which traditionally have been dedicated to their primary users alone. In the case, this sets new requirements to future radio technologies to deal with this po

26、ssible scenario. In November 2008 the US FCC issued a report and order which adopts rules to allow unlicensed “white space“ devices to operate in the broadcast television spectrum at locations where that spectrum is not being used by licensed primary users.

27、cope The present document provides the objectives and properties for and formulates an overall and harmonized technical concept for Cognitive Radio Systems. Both infrastructure as well as infrastructure-less radio networks will be covered. The main scope of the present document is to illustrate how

28、the reconfigurability and cognition functionalities can be introduced in the future radio networks both on the terminal and network sides. Based on such system concept and requirements the identification of candidate topics for standardization at ETSI concludes this study. The feasibility study incl

29、udes also a survey of related activities in other standardization bodies. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
