Feasibility
and sharing studies on the potential shared use of the 6425-7125 MHz frequency
band between MFCN and Wireless
Access Systems including Radio Local Area Networks (WAS/RLAN).
|
SE45_04
|
Study possible technical conditions for the
potential shared use of the band 6425-7125 MHz between MFCN and Wireless Access
Systems including Radio Local Area Networks (WAS/RLAN). This would include investigation
on sharing mechanisms/rules, and a range of sharing scenarios based on various
deployment assumptions.
Close
collaboration is needed between ECC PT1 and WG SE / PT SE45. ECC PT1 should
provide MFCN parameters (a range of parameters, including macro Base Stations aligned
with characteristics used in the WRC-23 studies) and WG SE / PT SE 45 should
provide suitable RLAN parameters (ref. work item SE45_04).

Possible further work related to the protection of incumbents would be further assessed, if necessary, at a later stage.
The work under this work item here should not be considered as a decision on the future use of 6425-7125 MHz frequency band.

Review and revise, as
appropriate, ECC Recommendation (08)02 on “Cross-border coordination for
Mobile/Fixed Communications Networks (MFCN) in the frequency bands 900 MHz and
1800 MHz excluding GSM vs. GSM systems” to consider introduction of 5G New

To address issues due
to usage of aerial UE in border areas
|
|
Guidance on the use of
aerial UE in border areas operating in the bands 703-733 MHz, 832-862 MHz,
880-915 MHz, 1710-1785 MHz, 1920-1980 MHz, 2500- 2570 MHz and 2570-2620 MHz

The following issued
could be addressed:
• aerial
UE usage at the border with and without roaming agreements,
• issues
related to “no transmit zone” area in the border areas,
• possible
solutions to avoid harmful interferences due the usage of aerial UE at the
border.
The approach of a toolbox for administration can
be considered as appropriate.

CEPT Report

Harmonised technical and operational conditions for the usage of
non-active antenna systems aerial terminal stations in harmonised MFCN bands (EC Mandate).
|
|
Task 1
Assess the feasibility and the relevant conditions
of radio communications between non-AAS aerial terminal stations (ATSs) based
on 4G/LTE and 5G NR technology and wireless terrestrial systems capable of
providing electronic communications services using the EU-harmonised frequency
bands:
·
700 MHz, 800 MHz, 900 MHz, 1800 MHz, paired
terrestrial 2 GHz, paired 2.6 GHz and unpaired 2.6 GHz, with non-AAS
terrestrial base stations.
·
1800 MHz, paired terrestrial 2 GHz, paired 2.6 GHz,
unpaired 2.6 GHz with AAS terrestrial base stations.
Task 2
Pursuant to the outcome of
Task 1, develop least restrictive harmonised technical and operational
conditions for the radio communications between non-AAS ATSs based on 4G/LTE
and 5G NR technology and wireless terrestrial systems capable of providing electronic
communications services using the related EU-harmonised bands. These conditions
should be consistent with the existing EU regulatory framework applicable to
the frequency bands under consideration. They should ensure interference
mitigation and appropriate co-existence with incumbent radio
services/applications in the same band and in adjacent bands, in line with the
regulatory status of these services/applications. The CEPT may develop
appropriate receiver characteristics for radio equipment as part of the
harmonised technical conditions. Based on such harmonised technical and
operational conditions, the CEPT may further recommend to ETSI to consider the
results of this study when developing relevant harmonised standards.

Investigate the modelling of 5G AAS (both in-band and unwanted domain) based on laboratory and other measurements as appropriate of commercially available equipment:
1) Assess existing models against measurements
2) Consider modifications to existing model if differences are seen
3) If modification is not feasible then develop new model

ECC Report first, then if appropriate a Recommendation
This task should investigate the modelling aspects of 5G AAS:
1) in the in-band domain
2) in the unwanted domain
The model should cover the relevant aspects of real antenna system (e.g. grating lobes) based on the results of laboratory measurements of 5G AAS.
