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.

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

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.
