Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS). Introduction The present document summarizes the feasibility studies carried ou
15、t by ETSI TC-RRS since the establishment of the Technical Body in January 2008. The area of studies has been Software Defined and Cognitive Radio Systems - collectively called Reconfigurable Radio Systems. In addition to the (interim) summary of the still ongoing studies the present document also su
16、mmarizes the so far identified topics, which are regarded by TC-RRS as candidates for creating ETSI Technical Specifications. This summary in the present document provide basis for decision making at ETSI Board level on standardization of some or all topics of Reconfigurable Radio Systems. ETSI ETSI
17、 TR 102 838 V1.1.1 (2009-10) 51 Scope The present document provides summary of the feasibility studies and work carried out by TC-RRS and its Working Groups since January 2008. The Working Groups are responsible for following study areas: WG1: RRS System Aspects. WG2: Reconfigurable Radio Equipment
18、Architecture. WG3: Functional Architecture and Cognitive Pilot Channel (in Cognitive Radio Network Management). WG4: RRS Public Safety. Furthermore, aspects not covered by the RRS Working Groups have also been added, see clause 6. As a whole these studies have covered radio system technologies more
19、generally known as Software Defined Radio and Cognitive Radio.

27、dio operational environment and established policies and to monitor usage patterns and users needs; to dynamically and autonomously adjust its operational parameters and protocols according to this knowledge in order to achieve predefined objectives, e.g. more efficient utilization of spectrum; and
28、to learn from the results of its actions in order to further improve its performance. NOTE 1: Radio operational environment encompasses radio and geographical environments, and internal states of the Cognitive Radio System. NOTE 2: To obtain knowledge encompasses, for instance, by sensing the spectr
29、um, by using knowledge data base, by user collaboration, or by broadcasting and receiving of control information. NOTE 3: Cognitive Radio System comprises a set of entities able to communicate with each other (e.g. network and terminal entities and management entities). NOTE 4: This definition follo

31、ware Defined and/or Cognitive Radio Systems software defined multiradio: device or technology where multiple radio technologies can coexist and share their wireless transmission and/or reception capabilities, including but not limited to regulated parameters, by operating them under a common softwar
32、e system NOTE 1: Examples of the regulated parameters are frequency range, modulation type, and output power. NOTE 2: Common software system represents radio operating system functions. NOTE 3: This definition does not restrict the way software is used to set and/or change the parameters. In one exa
33、mple, this can be done by the algorithm of the already running software. In another example, software downloading may be required. software defined radio: radio in which the RF operating parameters including, but not limited to, frequency range, modulation type, or output power can be set or altered
34、 by software, and/or the technique by which this is achieved NOTE 1: Excludes changes to operating parameters which occur during the normal pre-installed and predetermined operation of a radio according to a system specification or standard. NOTE 2: SDR is an implementation technique applicable to m
35、any radio technologies and standards. NOTE 3: SDR techniques are applicable to both transmitters and receivers.

40、esearch Forum 4 Reconfigurable Radio Systems There are several factors driving the future evolution of radio technologies towards more flexible and reconfigurable radio systems: Increasing growth of mobile traffic in terms of subscribers, data volumes and data rates There are more than 3 billion mob
41、ile 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 share the radio frequencies among multiple services and radio networ
42、ks are needed. ETSI ETSI TR 102 838 V1.1.1 (2009-10) 8Multitude 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 application from the radio platf
43、orm. 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 order to reach the cost a
44、nd energy efficient use of overall radio communications capacity. Regulators are starting to consider the extension of the possibility to allow secondary access to frequency bands, increasing spectrum utilization In order to meet the increasing data traffic volumes regulators have started to conside
45、r 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 possible scenario. 4.1 Networ

48、tiradio User Equipment represents a user device, equipped with a software defined multiradio technology, which makes the radio capabilities reconfigurable. Reconfiguration may include installation and loading of new radio software applications into the user equipment or modification of radio paramet
49、ers including also the radio frequency band used to carry the user traffic. Since a MUE has multiple radios, which can be active at the same time, it may have connections to multiple radio networks at the same time. Some of those radio networks may deploy cognitive radio technology to use radio frequencies in agile manner, others may use conventional radio technologies on their native frequency bands. Besides the ordinary user data radios a MUE may also use some radios to assist the cognitive control functions. Examples of such radios are spectru
