ECC Report

Evaluation of receiver parameters and the future role of receiver characteristics in spectrum management, including in sharing and compatibility 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
  6. Receiver measurements of common digital systems

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

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 with up to date measurements if available and to complete with additional systems if possible

To investigate how aggregated spurious emissions should be addressed in sharing and compatibility studies.

To investigate deriving emission masks or statistical distributions (e.g. in both cases based on measurements representing typical performance of equipment) for use in sharing and compatibility studies.

The result of this  work item should be considered when determining whether a revision of ECC Rec (19)02 is required.

Other Development of an algorithm for receiver Intermodulation (IM)
Development of an algorithm for calculation of Receiver Intermodulation products considering its future implementation in SEAMCAT
S: 14-09-2018
T: 01-09-2020

Deliverable: Others: Algorithm for Intermodulation

The algorithm should

-       be able to work in the frequency domain

-       be applicable for various modulation formats between an interfering Link TX and victim Link RX.

-       run fast enough to allow for a sufficient statistical number of eventswithin a reasonable time.

-       contain a sufficient number of parameters  to reflect various RX models

Once the algorithm is considered stable and agreed in WG SE, STG will implement the algorithm in SEAMCAT.

* 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.
