Terms of Reference for TC RRS WG 1: System Aspects, Cognitive functionalities and Radio Equipment Architecture (SCREA)

Responsibility

·        To collect and define requirements on Reconfigurable Radio Systems from relevant stakeholders

·        To develop and maintain a common technical framework for SDR and CR systems standardization in TC RRS regarding system level aspects

·        To define the cognitive functionalities for Reconfigurable Radio Systems

·        To propose common reference architectures for SDR/CR radio equipments (mobile handset devices, radio base stations etc) in such a way, that those reference architectures can be used by TC-RRS;

·        To collect and define the requirements and scenarios for common reference architectures from relevant stakeholders

·        To build on the proposed common references architecture by defining related functionalities: interfaces and protocols;

·        To identify gaps, where existing ETSI and 3GPP standards do not fulfil the requirements by covering important aspects of the reference architectures, and suggest and pursue further standardization activities to fill those gaps;

·        To ensure the coverage of the most relevant standardization bodies across the globe;

·        To deliver its findings in the form of Technical Reports, Technical Specifications and other relevant ETSI deliverables as appropriate.

Areas of activity

·        Standardization activities in Reconfigurable Radio Systems encompassing radio system and interface solutions related to Cognitive Radio Systems 

·        Standardization activities related to LSA (Licensed Shared Access) regime implementation in the band 2.3-2.4 GHz and possible future extensions to other bands depending on the regulatory studies 

·        Standardization activities related to White Spaces in the UHF TV bands which may encompass both coordinated and uncoordinated approaches and possible future extensions to other bands depending on the regulatory studies 

·        The above activities may include: 

• definition of use cases and working assumptions 
• definition of system requirements 
• definition of system architecture(s) and related (cognitive) management entities (spectrum management, radio resource management, etc)
• definition of related interfaces 

·        Preparation of System Reference Documents (SRdoc) in the area of Reconfigurable Radio Systems as appropriate 

·        Preparation of ETSI Technical Reports, Technical Specifications and European Norms as appropriate

 

·        Study on definition of common reference architectures for SDR/CR radio equipments on functional and logical level; 

·        Co-ordination of related requirements in order to produce a consistent set of ETSI Deliverables and Standards and to undertake measures to efficiently continue and stimulate further related work within ETSI; 

·        Draft and propose liaison with relevant external organizations such as SDOs under same topics; 

·        Propose establishment of external relationships (and joint working groups) where and when ever needed. Formal relationships will be established using the normal processes via the ETSI Secretariat.

Organization and working methods/ Collaboration with other bodies

·        TC RRS SCREA shall work in accordance with the ETSI Directives and, in particular, the Technical Working Procedures 

·        TC RRS SCREA will liaise with the other TC RRS working groups as appropriate 

·        TC RRS SCREA shall provide progress reports to TC RRS
