Cooperative Communication in NSA and SA 5G Networks

Abstract

AbstractThe 5G cellular system is a promising new radio network to provide an ultra-high user performance and experience by enhancing various advanced techniques from previous network generations, particularly 4G. Cooperative communication is one of the most powerful techniques, that allows each User Equipment (UE)) instantaneously to associate with more than one Base Station (BS). In Stand Alone (SA) network architecture where 4G and 5G networks operate independently, cooperative communication technique is reformed as Coordinated Multi-Point Processing (CoMP) in which the UE can have connections to either 4G or 5G BSs. In Non-Stand Alone architecture where the 4G and 5G networks coexist and co-operate together, the cooperative communication technique is officially called EN-DC (Evolved-Universal Terrestrial Radio Access-New Radio) and allows the UE to access both 4G and 5G technologies at the same time. In this paper, the performance of UE in terms of coverage probability is analyzed in an urban area with different scenarios such as CoMP between 4G BSs, EN-DC, and CoMP between 5G BSs.KeywordsDual connectivityCoordinated Multi-point Processing5GPoisson Point ProcessCoverage probability
