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.
