Overall Scope and Objectives

The ETSI Technical Committee (TC) on Reconfigurable Radio Systems (RRS) has the responsibility for standardization activities related to Reconfigurable Radio Systems encompassing system solutions related to Software Defined Radio (SDR) and Cognitive Radio (CR), to collect and define the related Reconfigurable Radio Systems requirements from relevant stakeholders and to identify gaps, where existing ETSI standards do not fulfil the requirements, and suggest further standardization activities to fill those gaps.

Technical Relevance to QoSMOS

During the QoSMOS lifetime, ETSI RRS was dealing with several active work items which are of interest for QoSMOS:

Study Item and Use Cases

- Technical Reports

  • TR 103 067 “Feasibility study on for Radio Frequency (RF) performances for Cognitive Radio Systems operating in UHF TV band WS”
  • TR 101 571 “Feasibility study for coexistence between CRS operating in TV WS band and RF Cable Networks services”
  • TR 102 947 “Use Cases for building and exploitation of Radio Environment Maps for intra-operator scenarios”
  • TR 102 684 “Feasibility Study on Control Channels for Cognitive Radio Systems ”
  • TR 102 944 “Use cases for baseband interfaces for unified radio applications of mobile device”
  • TR 102 967 “Use Cases for Dynamic Declaration of Conformity”
  • TR 102 970 “TR Use Cases for spectrum and network usage among Public Safety, Commercial or Military”
  • TR 102 945 “RRS Glossary and Terms”

- Technical Specifications

  • TS 102 946 “System requirements for Operation in UHF TV Band White Spaces”
  • TS 102 968 “System requirements for Reconfigurable Radio Systems operating in IMT-Bands and GSM-Bands for intra-operator scenarios”
  • TS 102 969 “Radio Reconfiguration related Requirements for Mobile Devices”

Status and outlook for QoSMOS

Several contributions/inputs related to QoSMOS were provided by QoSMOS partners to ETSI RRS working groups. TR 102907 and TS 102946 were led by members of QoSMOS. The Work Item on “System Requirements for Operation in whitespace Frequency Bands” (TS 102 946) was one of the major technical specifications in which QoSMOS partners contributed. At this end of QoSMOS project, since the requirements are quite mature, ETSI RRS was currently discussing the way forward and the approval of new work items. After having progressed with the work on use cases and requirements definition, ETSI RRS planned to create new work items on the definition of the architecture and protocols for Cognitive radio systems operating in TVWS band.

Potential work item will deal with the definition of the system architecture for the use of spectrum by White Space Devices (WSDs), specifically in the UHF TV Bands. The scope of the work will be to define the architecture of a system which can allow operation of WSDs based on information obtained from Geo-location databases.  The architecture will consider both uncoordinated use of White Space (where there is no attempt to manage the usage of channels by different WSDs) as well as coordinated use of White Space (where some form of channel management and/or coexistence techniques are employed to efficiently use the White Space)

ETSI RRS was also discussing a second work item defining the system architecture for the information exchange between different Geo-location Databases (GLDBs) enabling the operation of White Space Devices (WSDs. The architecture stems from the system requirements described in the section 7.1 (Terrestrial Broadcasting Service Protection Requirements) of ETSI TS 102 946 ”System requirements for operation in UHF TV Band White Spaces”.


The architecture work will serve as an input for defining the Harmonized Standards and European Standards that are part of the EC mandate for Reconfigurable Radio Systems (M/512).
