Proceedings ArticleDOI
Deep reinforcement learning based computation offloading and resource allocation for MEC
TL;DR: This paper considers a multi-user MEC system, where multiple user equipments can perform computation offloading via wireless channels to an MEC server, and proposes RL-based optimization framework to tackle the resource allocation in wireless MEC.
Journal ArticleDOI
An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems
TL;DR: The analysis shows that the estimation performance of the proposed approach improves when the large-scale/massive MIMO systems are employed and the approximate Cramér-Rao bound ofThe proposed estimator for the 2-D localization is derived.
Journal ArticleDOI

TL;DR: This paper evaluates the relevant PHY and MAC techniques for their ability to improve the reliability and reduce the latency and identifies that enabling long-term evolution to coexist in the unlicensed spectrum is also a potential enabler of URLLC in theUnlicensed band.
Journal ArticleDOI
Secrecy Transmit Beamforming for Heterogeneous Networks
Tiejun Lv,Hui Gao,Shaoshi Yang +2 more
TL;DR: This paper investigates secure communications in a two-tier downlink HetNet, which comprises one macrocell and several femtocells, and considers an orthogonal spectrum allocation strategy to eliminate co-channel interference.

Secrecy Transmit Beamforming for Heterogeneous Networks
Tiejun Lv,Hui Gao,Shaoshi Yang +2 more
TL;DR: In this paper, the authors investigated secure communications in a two-tier downlink HetNet, which comprises one macrocell and several femtocells, and proposed two cooperative STBs which rely on the collaboration among the macrocell base station and the adjacent femtocell base stations (FBSs).
