5G Cellular and Fixed Satellite Service Spectrum Coexistence in C-Band

Resource Allocation for Cognitive Satellite Uplink and Fixed-Service Terrestrial Coexistence in Ka-Band

This paper addresses the cognitive Geostationary Orbit (GSO) satellite uplink where satellite terminals reuse frequency bands of FixedService (FS) terrestrial microwave links which are the incumbent users in the Ka 27.5-29.5 GHz band. In the scenario considered herein, the transmitted power of the cognitive satellite user has to ensure that the interference impact on potentially present FS link...

Compatibility between Fixed Satellite Service uncoordinated receive Earth Stations and the Fixed Service in the band 17.7-19.7 GHz

HAPS Gateway Link in the 5850-7075 MHz and Coexistence with Fixed Satellite Service

Gateway link is essential to connect HAPS platform to terrestrial based networks. This crucial link is incorporated in HAPS fixed service spectrum allocation in considerably high frequencies, renders the link for more attenuations by atmospheric gases, and rain effects, especially when the regional climate is not favorable. However, under the agenda item 1.20 of World Radio Conference-2012 (WRC...

Feasibility of Cellular Networks and Radar Coexistence in S Spectrum Band

Spectrum sharing is an efficient solution for spectrum shortage. This paper presents mathematical analysis of a typical coexistence scenario between LTE and radar systems in 2.7-2.9 GHz bands. We present the interference analysis of multiple base stations (BSs) and mobile stations (MSs) on the primary radar. The joint distribution of power-controlled and non powercontrolled interference is also...

Spectrum Database for Coexistence of Terrestrial Fs and Fss Satellite Systems in the 17.7-19.7 Ghz Band

In this article we develop a database-based spectrum access for the Ka band, allowing fixed satellite services (FSS) receivers to coexist with the terrestrial fixed services (FS) system, thus increasing the downlink capacity of the satellite system. The main focus of this paper is to study FS interference to FSS user terminal receivers in the 17.7-19.7 GHz band as the interference from FSS to F...
