This paper studies user scheduling and power allocation problem to maximize the energy
efficiency (EE) for non-orthogonal multiple access (NOMA) in downlink Coordinated Multi …

Abstract In Non-Orthogonal Multiple Access (NOMA), the best way to fully exploit the benefits
of the system is the efficient resource allocation. For the NOMA power domain, the allocation …

Non-orthogonal multiple access (NOMA) is a highly promising multiple access strategy for
wideband communication systems due to its high spectral efficiency. However, in multi-cell …

In this paper, we investigate energy optimization in multi-cell and multi-carrier non-
orthogonal multiple access (NOMA) networks. We apply a load-coupling model for NOMA …

Non-orthogonal multiple access (NOMA) holds the promise to be a key enabler of 5G
communication. However, the existing design of NOMA systems must be optimized to …

This paper investigates the transmission energy minimization problem for the two-user
downlink with strictly heterogeneous latency constraints. To cope with the latency constraints …

This paper investigates the joint subcarrier and power allocation problem for the downlink of
a multi-carrier non-orthogonal multiple access (MC-NOMA) system. A novel three-step …

Non-orthogonal multiple access (NOMA) is considered a potential technique in fifth-
generation (5G). Nevertheless, it is relatively complex when applying NOMA to a massive …

In this paper, we investigate energy efficiency (EE) maximization in multicell multicarrier non-
orthogonal multiple access (MCMC-NOMA) networks with hardware impairments (HIs). We …
