Edge Caching and Computation Offloading for Fog-Enabled Radio Access Network
TL;DR: The problem is formulated to minimize the total energy consumption of all the UEs by optimizing the transmit power of the user equipments, caching strategies and the cooperation factor, which is a non-convex programming problem.

Resource Allocation Using Gradient Boosting Aided Deep Q-Network for IoT in C-RANs
TL;DR: This paper proposes a GBDT-based DQN framework for the DRA problem, where the heavy computation to solve SOCP problems is cut down and great power consumption is saved in the whole C-RAN system.
Proceedings ArticleDOI
Intelligent Reflecting Surfaces-Supported Terahertz NOMA Communications
Yijin Pan,Kezhi Wang,Cunhua Pan +2 more
TL;DR: The sum rate is maximized for the intelligent reflective surface (IRS) assisted terahertz (THz) non-orthogonal multiple access (NOMA) communication system and a novel algorithm is proposed to alternatively optimize the IRS phase shift, the sub-band allocation, and power control.
Journal ArticleDOI
A Bipartite Graph Approach for FDD V2V Underlay Massive MIMO Transmission
TL;DR: In this paper, a bipartite graph approach for frequency division duplexing (FDD) vehicle-to-vehicle (V2V) underlay massive MIMO transmission is proposed.

Novel energy detection using uniform noise distribution
TL;DR: Three novel detectors based on uniformly distributed noise uncertainty as the worst-case scenario are proposed andumerical results show that the new detectors outperform the conventional energy detector with considerable performance gains.
