A tractable approach to coexistence analysis between COMPASS and TD-LTE system

Abstract

With the rapid development and widespread deployment of TD-LTE system, its inter-system coexistence with Compass Navigation Satellite System (COMPASS) has become a big problem. To ensure the coexistence between the two systems operating in adjacent bands in the same geographical area, a tractable coexistence analysis approach is proposed and the outage probability is derived using stochastic geometry in this paper. Compared with the traditional Monte Carlo systemlevel simulation, our proposed interference analysis model is efficient and adaptive to the increasingly opportunistic and dense placement of base stations. Moreover, we formulate a Maximum Adjacent Channel Interference Ratio (Max-ACIR) resource scheduling algorithm, which reduces the interference from TD-LTE uplink to COMPASS downlink. Finally, protection criterion for coexistence is given via simulation.
