Research of Fairness in Coordinated Multipoint Heterogeneous Networks with Non-Orthogonal Multiple Access

Abstract

In this study we investigates a power allocation problem for maximizing the minimum achievable users’ throughput in downlink coordinated multipoint(CoMP) with non-orthogonal multiple access (NOMA) using successive interference cancellation (SIC) First non-orthogonal multiple access (NOMA) is one of the promising candidates in 5G system NOMA offer a set of benefits including great channel gain and spectrum efficiency Second we combine CoMP in able to enhance the quality of service for the Cell edge user in Heterogeneous Network The original mathematical model of the network is a nonlinear programming problem Converting the original model into a mixed integer linear programming problem with piecewise-RLT and mathematical approximate skills of the logarithmic term Finally using C++ combined with CPLEX to simulate get the best solution of the whole model
