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 , ECC Report

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

a.             To be used by other 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 Recommendation (02)05, ERC Recommendation 74-01 or European Harmonised Standards.

c.             Further investigate and provide methodologies on the use of typical performance in sharing/compatibility studies. This may include:

i.              Guidance on defining typical performance of the equipment through measurements;

ii.             Defining a methodology for developing the distribution of values for typical performance of equipment, for sharing/compatibility studies, this may include a guidance on determining an ‘average’ level of spurious emissions.

iii.            Defining a methodology to introduce power distribution in sharing/compatibility studies.

iv.            Guidance on use of a sensitivity analysis.

d.             Provide guidance on how the boundary between the Out of Band domain and the Spurious domain based on the 250% rule relates to the discontinuity of typical unwanted emissions in the Out-of-band and Spurious domains.

e.             Look for any baseline assumptions that can be defined for the typical performance of equipment that can be used in sharing/compatibility studies.

f.             Changing limits in ERC Recommendation 74-01 is outside the scope of this work. However, developing an informative annex to 74-01 could be within scope.

g.             Liaise with other SE project teams and ETSI where appropriate.

h.             Use ECC report 249 as a basis for this work. Other work references could include ECC Report 207 and ERC Report 065 which give examples of previous studies where performance better than the limits were used.

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.

* 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.
