  Abstract

Resolution 221 requests the ITU-R to conduct studies, as a matter of urgency, on the feasibility of utilizing HAPS system as a base station to provide IMT-2000 services. And HAPS base stations should not cause harmful interference to the cellular IMT-2000 services.
To study on the interference between HAPS system and cellular system is divided into two cases. One is the interference into HAPS system from the cellular system and the other is the interference into the cellular system from HAPS system. Since the former case has been already studied[I], this paper describes the interference effects into Cellular system from HAPS system considering the HAPS airship's antenna pattern, and estimated by the interference to the noise power ratio(l/N) with various parameters, such as the transmitting power, the number of users per cell, maximum antenna gain and the multibeam cell radius of HAPS.
With the proposed estimation, we can determine the optimum values of various parameters in HAPS IMT-2000
system.
