Compatibility between both MFCN operating in 3400-3800 MHz and WBB LMP operating in 3800-4200 MHz with Radio Altimeters (RA) operating in 4200-4400 MHz

Assessment of susceptibility of deployed RA receivers operating in 4200-4400 MHz, while taking into account any civil aviation initiatives on improving RA receivers, in order to study the following compatibility scenarios:
1) Unwanted emissions from MFCN operating in 3400-3800 MHz and WBB LMP operating in 3800-4200 MHz into 4200-4400 MHz radio altimeters band
2) Impact of blocking of radio altimeters from 3400-3800 MHz MFCN in-band emissions and from 3800-4200 MHz WBB LMP in-band emissions
Note: the results of this study could trigger further actions as appropriate from ECC or other entities.
Provide relevant long term MFCN operational parameters in 3.4-3.8 GHz for the development of future MOPs by RTCA/EUROCAE for resilient radio altimeters.

It is recognised that realistic scenarios and parameters for RA and MFCN AAS parameters are needed before compatibility studies can be commenced.
Based on the results of the study, consider the need for possible future steps, e.g. improvement of RA susceptibility to interference, in particular regarding blocking characteristics.
It is to be noted that radio altimeters are used globally and once installed they are used over many years. Therefore, development of future MOPS(Minimum Operational Performance Standards) for RA should be forward-looking as well as considering the various 5G MFCN deployments already existing in frequency bands both below 4.2 GHz as well as above 4.4 GHz, in both Europe and globally.
Once the
long-term MOPS are available (currently expected in 2024) the studies
undertaken so far will be assessed and updated as needed. This could be a
separate study under a different timeline from the current WI timeline, or a
new WI.
Studies on 3.8-4.2 GHz have been triggered by the CEPT work in response to EC Mandate (see WI PT1_47)

Study and assess the technical feasibility of the shared use of the 3.8-4.2 GHz frequency band by terrestrial wireless broadband systems providing local-area (i.e. low/medium power) network connectivity. In this regard, consider sharing solutions, including innovative features, which ensure:
- protection and the future evolution and development of incumbent users sharing this band, in particular receiving satellite earth stations and terrestrial fixed links;
- coexistence of terrestrial wireless broadband systems providing local-area network connectivity and uses operating in adjacent bands such as terrestrial systems providing wireless broadband electronic communications services in the 3.4-3.8 GHz frequency band and radio altimeters on board aircraft in the 4.2-4.4 GHz frequency band.

Protection and future evolution and development of incumbent users, such as earth stations and fixed links.
Coexistence with applications in adjacent bands, such as MFCN in 3.4-3.8 GHz and radio altimeters in 4.2-4.4 GHz.
PT1 will assist WG FM in defining the harmonised technical conditions, possibly a BEM.
Meetings of PT1 and WG FM on this topic should take place in the same week and at the same location.
Interim Report: 11/2022
Technical
studies to be made available to FM60:
- Preliminary results in September 2023.
- Stable studies at the latest in February 2024.
Draft ECC Report for PC approval at ECC#63 in March 2024 and publication at ECC#64 in June 2024.
Coexistence with radio altimeters are covered by WI PT1_40.
ECC Reports under PT1_47 and PT1_40 are used as appropriate to contribute to the CEPT Report.
Note: final WI deadline is for the CEPT Report to be submitted to WGFM, for PC approval at ECC#64 in June 2024 and publication at ECC#65 in November 2024

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.

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.

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.
