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: 31-05-2021

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.
Algorithm for general application should be developed with a complete analysis not limited to an extension of the one currently being developed on the basis of scenario between LTE (wideband) as interfering signal and TETRA(narrow band) as victim (see ECC Report 283)
see also ECC Report 310

-       run fast enough to allow for a sufficient statistical number of events within 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.

ECC Recommendation Receiver resilience to transmission on adjacent frequency ranges

This deliverable is to:

  1. Be used by CEPT / ECC in its sharing and compatibility work. and/or to beused by ETSI when developing Harmonised  Standards
  2. Provide limits and/or levels for receiver resilience from transmissions onadjacent frequencies based on various sources of information (ETSI,Measurement, data sheet)
  3. Provide limits and/or levels for a wide range / categories of receivers.Considering spectrum usage (e.g. ERC/REP 25).

S: 31-01-2020
T: 30-12-2022

Reference: ECC Report 310.

SE21 is first tasked with refining the scope of thework to be undertaken on this recommendation and propose updates to this workitem where appropriate

The primary objective of this work item is to develop a recommendationon receivers. Technical background of this new ECC Recommendation could begathered in a supplementary ECC document. This may lead to an update of thescope of WI accordingly.

ECC Report Measurement methodologies for 5G AAS in the field PT1_35
Develop techniques and methodologies to determine or estimate TRP (with equivalent measurement metrics) by field measurements for both in-band and unwanted emissions (out of band domain and spurious domain) of 5G AAS. In order to facilitate checking compliance with national regulations and performing interference investigations.
S: 20-05-2020
T: 31-05-2021
Develop techniques and methodologies for measurement of 5G AAS in the field for the following:
1) In band signal evaluation (power limits, BEM)
2) Out of band emission evaluation 
3) Spurious emission evaluation 
To determine TRP or find a method to estimate TRP with other measurement metrics.
The determination of the TRP should also be used to evaluate the compliance with existing regulations (e.g. ERC REC. 74-01).

Laboratory measurements of 5G AAS as discussed in other groups (such as ECC PT1 or ITU-R WP5D) could be used for comparison / verification of the proposed methods of 5G AAS measurements in the field. It is recognised that additional a priori information on 5G AAS e.g. details of the antenna (e.g patterns)  are needed to develop or apply specific types of  methodologies for field measurements.
The TRP measurement techniques / methodologies may be evaluated compared with existing 5G AAS information and models. Differences in results between measurement  and models may raise the need for further work within ECC after the completion of this work. It is noted that the expertise on 5G AAS modelling is within ECC PT1.

WI to be done in cooperation with ECC PT1 and ECC FM22

* 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.
