Operational region of overlay D2D communications

2015 IEEE International Conference on Communications (ICC), 2015
An important enabler towards the successful introduction of any new element/feature to the cellular network, such as the ability to allow for direct, device-to-device (D2D) communications, is the investigation and characterization of the operational conditions, e.g., density of users, where its deployment will enhance performance.

D2D CSI feedback for D2D aided massive MIMO communications

2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016
We consider fast fading massive MIMO systems in Frequency Division Duplex (FDD) mode and propose a communication scheme based on Device-to-Device (D2D) cooperation and statistical channel state information (CSI) feedback. User terminals (UT) are conveniently clustered and cooperate within a cluster to create a virtual MIMO at a target UT via D2D ...

The Role of Video Coding in D2D Communications

2017 IEEE Globecom Workshops (GC Wkshps), 2017
The development of Device-to-Device (D2D) communication provides potential for distributing data in mobile devices, offloading large amount of data traffic from the base station to mobile devices. It greatly enhances the system capacity, and makes the mass of high-quality video services possible.

Radio resource management of D2D communication

2014 IEEE International Conference on Communication Systems, 2014
Device-to-Device (D2D) is considered as a promising technique to improve resource utilization and provide new application in future wireless networks. This paper addresses the problem of radio resource allocation for D2D communication. Basically, resource allocation can be carried out in centralized or distributed manner.

Robust beamforming for D2D multicast communication

Physical Communication, 2020
Abstract In this paper, beamforming for device-to-device multicast communication under channel uncertainty arising from incomplete channel state information is considered. The problem is first formulated as a non-robust minimization problem subject to signal-to-interference-plus-noise ratio, transmit power and interference constraints.

Assessing Coverage and Throughput for D2D Communication

2018 IEEE International Conference on Communications (ICC), 2018
In this paper, we access the performance of a Device-to-Device (D2D) communication link. Particularly, we design a framework to evaluate performance with respect to coverage probability and average throughput. Our modeling framework considers a variety of D2D deployment scenarios (i.e., Outdoor-to-Outdoor, Outdoor-to-Indoor, and Indoor-to-Indoor ...

Interference aware approach for D2D communications

2016 IEEE International Conference on Communications (ICC), 2016
Device-to-device (D2D) communications enable the proximity communications among users with or without the use of the network infrastructure. D2D communications can increase the overall spectrum efficiency and reduce the power consumption thus a massive utilization of D2D is expected in the future 5G networks.

D2D cooperative communications for disaster management

2017 24th International Conference on Telecommunications (ICT), 2017
In this paper, we investigate a disaster management system using D2D cooperative communications. Specifically, we consider two D2D cells, one is in healthy area and the other is in disaster area, where a user equipment (UE) in healthy area aims to assist a UE in the disaster area to recover wireless information transfer (WIT) via an energy harvesting ...

DUE Distribution and Pairing in D2D Communication

2019 28th International Conference on Computer Communication and Networks (ICCCN), 2019
The D2D (Device-to-Device) communication has been very popular as it is a promising and low-cost solution to reduce the burden on the cellular network. However, there are rare concerns about the distribution and pairing of DUEs(D2D user equipments), which have a significant impact on QoS (Quality of Service) of D2D communication.

Introduction to D2D Communication

2014
Analysts predict an explosive growth in traffic demand on mobile broadband systems over the coming years due to the popularity of streaming video, gaming, and other social media services. While 4G wireless technologies are making a significant effort to keep up with this demand, the expectation is that cellular deployments will fall short of the ...
