In this letter, to minimize the total transmit power with constraints of the user data rate
requirements, the radio resource allocation problem for multi-cell and multi-carrier non …

In a multicarrier NOMA system, the subchannel allocation (SA) and power allocation (PA)
are intricately linked and essential for improving system throughput. Also, for the successful …

In this paper, we investigate the energy minimization for the cellular networks with non-
orthogonal multiple access (NOMA). Different from most of existing studies in NOMA …

In this work, we propose globally optimal power allocation strategies to maximize the users
sum-rate (SR), and system energy efficiency (EE) in the downlink of single-cell multicarrier …

This paper investigates the user clustering and power control in the uplink multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) networks. A joint optimization …

Non-Orthogonal Multiple Access (NOMA) technique is a remarkable component of 5G
wireless networks; since NOMA immensely augments the spectral efficiency and serves all …

Resource allocation problem is a key issue in multi‐carrier non‐orthogonal multiple access
(NOMA) networks. Maximum access problem and power allocation problem are two …

In this letter we consider a resource allocation problem for multi-user MIMO non orthogonal
multiple access (MU-MIMO-NOMA) downlink transmissions. Under the NOMA paradigm …

In this paper, we study joint transmission scheduling, rate selection, sub-channel allocation
and power assignment problem to maximize energy efficiency in downlink power-domain …

Multi-carrier based non-orthogonal multiple access (NOMA) is an effective method to meet
the ever-increasing demands of both user throughput and energy efficiency by multiplexing …
