Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS).
Introduction
The present document addresses, in particular, the studies carried out by ETSI TC-RRS related to the study reports
published by the working group WG1, WG2, WG3 and WG4. For example, the study results provided by ETSI
TC-RRS working groups have been considered for items of potential relevance to regulation authorities.
The present document provides a recommendation to ETSI TC-RRS working groups. It is outlined which technical
proposal of the working groups may require further regulatory actions in order to be deployed in the market.
As a European Standardization Organisation, ETSI receives mandate from the European Commission to develop
Harmonised Standards that have a regulatory status as they can be referenced to by manufacturers to ensure that their
products comply with the essential requirements of the R&TTE Directive [i.8]. It is then necessary to identify where the
implementation of CR and SDR technologies may impact on the development of Harmonised Standards. The aspects
discussed in the present document may motivate the creation of a related harmonized standard in the future.
In addition to that, some CR enablers (e.g. CPC) or functionality may impact on the conditions of use of one or several
spectrum bands. These modifications need to be identified and submitted for study purpose to regulatory bodies;
potentially CR enablers and functionalities need to be indentified which are beyond the scope of the present document,
which is limited to those addressed so far, in particular in ETSI RRS technical reports [i.1] to [i.6].

1 Scope
The present document gives recommendations related to the regulatory issues addressed in feasibility studies carried out
by the Working Groups 1-4 of TC-RRS since January 2008. The Working Groups are responsible for following study
areas:
• WG1: RRS System Aspects
• WG2: Reconfigurable Radio Equipment Architecture
• WG3: Functional Architecture and Cognitive Pilot Channel (in Cognitive Radio Network Management)
• WG4: RRS Public Safety
As a whole these studies have covered radio system technologies more generally known as Software Defined Radio and
Cognitive Radio.
The present document also addresses the outcome of previous work such as that carried out by TCAM as a result of the
Report drafted by its ad-hoc group on Software Defined Radios [i.7], in particular during TCAM meetings 17, 18 and
19.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
cognitive radio: radio, which has the following capabilities:
• to obtain the knowledge of radio 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
• 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 spectrum, 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).
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 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 a
