TL;DR: In this article, a joint optimization problem of UAV deployment, caching placement and user association for maximizing QoE of users is formulated, which is evaluated by mean opinion score (MOS).

TL;DR: Under the design of the RIS, the problem of increasing the number of RIS elements damaging the secrecy performance is solved and the networks can use traditional channel coding schemes to achieve secrecy.

TL;DR: The proposed HetNet is an interference-limited system and it outperforms the traditional HetNets in terms of the success probability; there exists an optimal pre-decided rate threshold that contributes to the maximum ASE; and Max-Rate achieves higher success probability and ASE than Max-RP but it needs the extra information of the interference effect.

TL;DR: This paper provides a comprehensive performance evaluation of UAV relay networks (UAVRNs) employing non-orthogonal multiple access (NOMA) technique and characterize the outage and ergodic capacity performance of NOMA-enabled UAV RNs.

TL;DR: This work analytically shows that index coding is more power efficient than superposition coding when appropriate caching contents are available for a pair of users and proposes a sub-optimal joint user clustering and power allocation scheme for a single-cell downlink non-orthogonal multiple access network.
