Interference Management Using Nonlinear Relaying

IEEE Transactions on Communications, 2010
We consider the three-node Gaussian relay channel where the relay observes a noisy version of the interference present in the source--destination link. We investigate three fundamental relaying approaches: linear relaying, memoryless nonlinear relaying, and compress-and-forward (CF).

Topological Interference Management for MIMO Interference Broadcast Channels [PDF]

IEEE Access, 2019
In this paper, we investigate the topological interference management (TIM) for MIMO interference broadcast channels (IBC) under the fixed topology, where only topology information is needed to cancel the inter-cell interference (ICI). For the single user case, where the MIMO IBC network is reduced to the MIMO interference channel (IC) networks, we ...

Multi-Antenna Interference Management for Coded Caching [PDF]

IEEE Transactions on Wireless Communications, 2020
A multi-antenna broadcast channel scenario is considered where a base station delivers contents to cache-enabled user terminals. A joint design of coded caching (CC) and multigroup multicast beamforming is proposed to benefit from spatial multiplexing gain, improved interference management and the global CC gain, simultaneously.

Capacity Improvement for Full Duplex Device-to-Device Communications Underlaying Cellular Networks

IEEE Access, 2018
In this paper, the capacity improvement of full-duplex (FD) device-to-device (D2D) underlaying cellular networks (CNs) is analyzed. A single-cell environment is considered with one half-duplex (HD) base station, multiple HD cellular user equipments (CUEs)

Optimal Power Allocation Based on Metaheuristic Algorithms in Wireless Network

Mathematics, 2022
An optimal power allocation is a fundamental challenge for massive multiple-input–multiple-output (MIMO) systems because the power allocation should be acclimated to time-varying channels and heavy traffic conditions throughout the communication network.

Resolving Entanglements in Topological Interference Management with Alternating Connectivity [PDF]

, 2014
The sum-capacity of a three user interference wired network for time-varying channels is considered. Due to the channel variations, it is assumed that the transmitters are only able to track the connectivity between the individual nodes, thus only the ...

Reinforcement Learning With Selective Exploration for Interference Management in mmWave Networks

IEEE Transactions on Machine Learning in Communications and Networking
The next generation of wireless systems will leverage the millimeter-wave (mmWave) bands to meet the increasing traffic volume and high data rate requirements of emerging applications (e.g., ultra HD streaming, metaverse, and holographic telepresence ...

The Mine Locomotive Wireless Network Strategy Based on Successive Interference Cancellation

Sensors, 2015
We consider a wireless network strategy based on successive interference cancellation (SIC) for mine locomotives. We firstly build the original mathematical model for the strategy which is a non-convex model.

Partially-Distributed Resource Allocation in Small-Cell Networks [PDF]

, 2014
We propose a four-stage hierarchical resource allocation scheme for the downlink of a large-scale small-cell network in the context of orthogonal frequency-division multiple access (OFDMA).

Unified 3D Networks: Architecture, Challenges, Recent Results, and Future Opportunities

IEEE Open Journal of Vehicular Technology
The very new evolution towards 6G networks necessitates a paradigm shift towards unified 3D network architectures, encompassing space, air, and ground segments. This paper outlines the conceptualization, challenges, and prospects of such a transformative
