Power Allocation For Non-Orthogonal Multiple Access In Hetnet With Imperfect Channel State Information |
Abstract | ||
---|---|---|
In this paper(1), power allocation problem is studied in nonorthogonal multiple access (NOMA) heterogeneous network (HetNet), in which base stations with NOMA protocol can communicate with multiple users in cell. The main aim of this paper is to maximize the energy efficiency (EE) by considering imperfect channel state information (CSI). It is proved that the optimization problem is non-convex due to the constraint of outage probability limit. Therefore, it's essential to transform the probabilistic problem by theoretical derivation. Then, an optimal search algorithm is proposed to achieve the power allocation. Finally, simulation results show that NOMA HetNet with the proposed algorithm has more advantages in EE compared with the related work for conventional orthogonal frequency multiple access (OFDMA) HetNet case. |
