Abstract
Fourth-generation mobile networks such as LTE and LTE-advanced [1], which are based on orthogonal frequency division multiple access (OFDMA), can only serve one user equipment (UE) at a time with a resource block (RB). In this thesis, we study non-orthogonal multiple access (NOMA), a multiple access technique that can serve two or more UEs at a time with a RB in order to increase overall performance. We consider the resource allocation problem in the case with heterogeneous RBs. Moreover, we combine NOMA with Coordinated Multi-Point (CoMP) [2] for edge UEs. We propose two resource allocation algorithms, which are called MaxWeightMatching NOMA (MEM NOMA) and MaxIndependentSet NOMA (MIS NOMA). The objective is to maximize the number of satisfied UEs. The simulation results show that the proposed algorithms have better performance, compared with other resource allocation algorithms.
