摘要：
In this paper, we examine a joint user pairing and dynamic power allocation (JUPDPA) design to maximize the energy efficiency (EE) in the multicell multiple-input multiple-output. (MIMO) - non-orthogonal multiple access (NOMA) downlink system. A novel JUPDPA scheme is proposed based on median and the euclidean norm of the channel vectors. In addition, base station dynamically allocates the transmission power to the paired users. Comprehensive numerical results illustrate that the proposed scheme attains higher energy efficiency as compared with the existing NOMA schemes and the conventional orthogonal multiple access (OMA) scheme.
