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 performance of non-orthogonal multiple access (NOMA) systems
over time-correlated Rayleigh fading channels, where the users have heterogeneous quality …

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 …

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

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 …

Non-orthogonal multiple access (NOMA) exploits successive interference cancellation
technique at the receivers to improve the spectral efficiency. By using this technique …

In this paper, energy efficient power allocation is considered for a multiuser uplink non-
orthogonal multiple access (NOMA) system under quality of service (QoS) constraints. Due …

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