To collect and review measurements in particular for 5G BS and UE 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 measurements of unwanted emissions should be taken into account 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.
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. Also to investigate the applicability for sharing and compatibility studies for wideband systems of the frequency separation between the center frequency and the spurious boundary as specified in ERC Recommendation 74-01. These updates should take Recommendation ITU-R SM.1541 and Appendix 3 of the RRs into account and may take Recommendations ITU-R SM.328-11, SM.329-13 and SM.1539-2 into account.
A new ECC Report, in addition to ECC Report 249, may be required to address the various investigations in order to keep ECC Report 249 focused on measurement consolidation.
The result of this work item should be considered when determining whether a revision of ECC Rec (19)02 is required.
Noting that the ECC Report 249 was updated during the 90th WG SE meeting in January 2022, the WI would continue to address 5G AAS measurements while keeping the available material as the baseline for the further work.
SE21 would also consider how the revision history of the ECC Report 249 could be addressed.
