Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio
spectrum Matters (ERM).
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document is the deliverable of phase 3 work by ETSI STF 386. It is a refinement of the concepts and
methods depicted in earlier documents by phase 1 and phase 2. Phase 1 has generated document ETSI TR 102 799 [i.2]
and phase 2 document ETSI TS 102 800 [i.6].
The refinement is based on the experience and lessons learnt during the course of a German national research project
called "C-PMSE" funded by the German Federal Ministry of Economics and Technology (BMWi). This project had the
aim of ensuring the high quality of productions with PMSE under a dynamically changing interference situation.
The present document therefore reflects several modifications to the originally proposed architecture of a cognitive
interference mitigation system and spectrum access for PMSE and to the methods of operating it.
As the majority of partners and experts participating in STF 386 were also partners on the German Research project, a
smooth transfer of public information gained in the research project to the STF 386 work was ensured.
The present document will highlight the changes made to the architectural concepts and operation methods for cognitive
interference mitigation with PMSE over the phase 1 and phase 2 deliverables as a consequence of the findings by the
German research project.
The present document provides recommendations on the interfaces that need to be standardized to ensure proper
functionality of interference mitigation techniques.
As the german research project ran a large demonstration tested at Messe Berlin, several tests of cognitive behaviour
have been conducted there and a deep understanding of necessary tests has been developed which serves as the basis for
defining recommended test cases in the present document. The aim is to recommend test cases that should be
incorporated in the relevant standards.
C-PMSE technology and measurement procedures should be incorporated in ETSI EN 300 422-1 [i.1] and
ETSI EN 301 489-1 [i.4] and ETSI EN 301 489-9 [i.7] as soon as practicable in order to encourage the development and
widespread use of cognitive PMSE systems in the market.
Although the testings and demonstrations with the German research project have focussed on UHF TV Band, the
findings on refinement of architecture and operation method are applicable to other bands.
