ECC Recommendation , ECC Report

To evaluate relevant receiver parameters, considering the future role of receiver parameters in spectrum management and sharing studies 

1)      Deliverable: ECC Report and after that a possible  ECC Recommendation to be used for sharing and compatibility studies

2)      Purpose of the deliverable:

  1. To define linkages between terminology and definitions used by different communities (include references to the ECC Report 252 on SEAMCAT User Manual)
  2. To identify the relevant receiver parameters on studies involving different services/applications -
  3. To evaluate their impact on study results by e.g. providing mathematical description (formulas)
  4. To ensure their usability in inter system studies, especially with respect to adjacent channels operation
  5. To develop a methodology for dealing with unlike bandwidth and different technologies. For example selectivity of the adjacent channel refers to same system opposed to systems having different bandwidths and signal types

3)       Background material for the deliverable can be taken from e.g:

  1. from ECC REC(02)01 Appendix A
  2. Receiver parameters/ TR on definitions in ETSI TR 103 265.

As a justification for this report, it should include a section dealing with past examples from ECC reports where the receiver parameters used for sharing studies show a different performance than the one that can be found in the reality (e.g. ECC Report 127, GSM-R, DTT receivers at700 MHz, ECC Report 191 (MFCN)

4)       While drafting of this report there should be interactive cooperation with ETSI on the different receiver parameters to ensure consistency,

5)     Identify possible upcoming issues from the receiver requirements and to provide feedback to ETSI.

6) Liaise with other PTs regarding receiver parameters of importance for compatibility and sharing studies

ECC Recommendation

Unwanted Emissions – Guidance and methodologies when using typical equipment performance in sharing/compatibility studies

a. To be used by CEPT / ECC groups when conducting sharing/compatibility studies

b. To provide clear guidance on the use of the typical performance of equipment in sharing/compatibility studies in addition to limits e.g. those set in ECC/EC deliverables or ETSI European Harmonised Standards.

c. Use ECC report 249 as a basis for this work.



S: 29-04-2016
T: 31-05-2019

Note: this recommendation may need to be reviewed, once the work to update ECC report 249  is completed (see e.g. WI21_22)

ECC Recommendation (19)02 is under public consultation.

Rev. ECC Recommendation Update of the ERC REC 74-01
To review and as necessary update ERC REC 74-01
S: 12-05-2017
T: 24-05-2019
The revision of ERC REC 74-01 has to consider the generic aspects of spurious emissions issues.

This review should involve consultation with the relevant technical and Working Groups within CEPT and ETSI on modifications needed.

SE21 is also invited in close cooperation with ETSI to consider how to manage the specific applications requiring regulatory provisions on spurious emissions. 

Some issues  have already been collected by SE21 in a Forum Group.

Revision of ERC REC74-01 is under public consultation.

Rev. ECC Report Revision of ECC Report 249
To update ECC Report 249 “Unwanted emissions of common radio systems: measurements and use in sharing/compatibility studies ” with new material
S: 25-01-2019
T: 30-09-2021

To collect and review measurements in particular for 5G BS and UE, fixed service and DTT measurements

To review as appropriate, the existing parameters withup to date measurements if available and to complete with additional systems if possible

This result of the revision should determine if a revision of ECC Rec (19)02 is required based on the new findings in the revised ECC Report 249.

* Target dates are seen as the intended date for the final approval of the related deliverable by the responsible entity. Internal deadlines for project teams and dates for the start of Public Consultations can be reflected in the remarks column. In general this implies that the draft deliverable should be completed by the project team one WG meeting earlier for publication.
