Methodologies for interference evaluation from the downlink of the fixed service using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the band 27.5-28.35 GHz
This Recommendation provides methodologies for the interference evaluation from the HAPS-to-ground transmission downlink of the fixed service (FS) using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the bands 27.5-28.35 GHz. This Recommendation contains three Annexes that provide methodologies for interference calculation, calculation of the e.i.r.p. of transmission from HAPS, interference evaluation in terms of C/I and examples of applications of the methodologies in the Appendix.
