In this paper, the performance of non-orthogonal multiple access (NOMA) is investigated
and optimized in a downlink space division multiple access network with a multi-antenna …

A key problem of content caching networks is that extra radio resource blocks are consumed
to push content objects, which leads to a decline of spectrum efficiency. To solve this …

In this paper, we investigate the problems of sum power minimization and sum rate
maximization for multi-cell networks with non-orthogonal multiple access. Considering the …

Non-orthogonal multiple access (NOMA) has been considered as a highly efficient
communication technology in the fifth generation (5G) networks by serving multiple users …

In order to apply downlink nonorthogonal multiple access (NOMA) to delay-sensitive
transmissions, we consider NOMA with delay quality of service (QoS) constraints and …

This paper designs a novel non-orthogonal multiple access (NOMA) unicast-multicast
system, where a number of unicast users (those who require different messages) and a …

This paper investigates the optimal resource allocation of a downlink non-orthogonal
multiple access (NOMA) system consisting of one base station and multiple users. Unlike …

We propose a robust beamforming design for non-orthogonal multiple access-based
multiple-input single-output downlink systems. In particular, the robust power minimization …

This paper is concerned with pilot transmission schemes in a large antenna system with non-
orthogonal multiple-access (NOMA). We investigate two pilot structures-orthogonal pilot …

To meet the growing demand of mobile data traffic in vehicular communications, the vehicle-
to-small-cell (V2S) network has been emerging as a promising vehicle-to-infrastructure …
