This paper investigates the power control problem for the downlink of a multi-cell non-
orthogonal multiple access system. The problem, called P-OPT, aims to minimize the total …

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 …

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 …

This paper investigates the power control problem for the uplink of a non-orthogonal multiple
access (NOMA) system with two cells. The game-theoretic approach is used to study the …

In this letter, the performance of optimal dynamic power allocation (PA) is analyzed for
downlink multi-carrier non-orthogonal multiple access (MC-NOMA) systems. We study the …

In this work, we propose a globally optimal joint successive interference cancellation (SIC)
ordering and power allocation (JSPA) algorithm for the sum-rate maximization problem in …

In this letter, we investigate a multi-cell uplink non-orthogonal multiple access (NOMA)
system with imperfect successive interference cancellation (SIC). The objective of the …

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 …

In this paper, resource allocation for a multi-carrier uplink non-orthogonal multiple access
(NOMA) system is studied. Unlike the existing works on multi-carrier uplink NOMA, in which …

In this letter, we consider a downlink non-orthogonal multiple access (NOMA) system where
a base station (BS) simultaneously communicates with multiple users. These users are …
