It is considered one of the novel features for 5G. The most obvious limitation that faces the URC is the interference which is severe at the cell edges. Hence, the use of the Interference Management (IM) techniques such as Fractional Frequency Reuse (FFR) and Soft Frequency Reuse (SFR) is most impor- tant to overcome the interference and make good use of URC. The previous studies focused on the analysis of FFR and SFR for either the regular (hexagonal) cellular network only or irregular (voronoi) cellular network. This paper introduces the FFR and SFR analysis for hybrid cellular network which is defned as a mixture that combines both of the regular and irregular cellular networks. So, in this paper, the FFR and SFR performance analysis would be carried out and compared for each of the regular, irregular and hybrid cellular networks in both downlink and uplink scenarios.

URC has a vital role in 5G. The URC has applications as reliable wireless coordination among vehicles and industrial automation [4]. * Eman M. Soultan emanmamdouh953@gmail.com Hala B.
