In this paper, we design a secure transmission scheme in uplink and downlink of non-
orthogonal multiple access (NOMA) system. In this scenario, two pairs of base stationuser …

In this paper, we study uplink-downlink non-orthogonal multiple access (NOMA) systems by
considering the secure performance at the physical layer. In the considered system model …

This paper investigates secure transmission for non-orthogonal multiple access (NOMA)
systems where the imperfect successive interference cancellation (SIC) is considered at …

In this paper, a novel approach is introduced to study the achievable delay-guaranteed
secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study …

In this paper, we analyze the secrecy outage probability (SOP) and the fairness of average
packet transmission time for a non-orthogonal multiple access (NOMA) system which …

A novel secrecy scenario of uplink non-orthogonal multiple access (NOMA) along with
cooperative jammer (s) to improve secrecy performance is studied in this work. We first …

In this paper, we consider the physical layer security of a downlink non-orthogonal multiple
access (NOMA) system, in which users' quality of service (QoS) requirements are …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …
