Resource Allocation for D2D Communication With Multiple D2D Pairs Reusing Multiple Channels

IEEE Wireless Communications Letters, 2019
In this letter, the goal is to maximize sum capacity of device-to-device (D2D) communication through a reuse of each radio channel by multiple D2D pairs while each D2D pair can access multiple channels. Since existing approaches cannot be easily extended to enable reuse of multiple channels by multiple D2D pairs in scenario with a high interference ...

D2D group communications security

2015 International Conference on Protocol Engineering (ICPE) and International Conference on New Technologies of Distributed Systems (NTDS), 2015
Proximity Services (ProSe) discovery or communications using LTE-based Device-to-Device (D2D) communications have been recently in the heart of the discussions about the advent of 5G networks. Meanwhile, their related security aspects are of a major concern especially when dealing with direct radio communications and large-scale deployment of D2D ...

A Survey on Security in D2D Communications

Mobile Networks and Applications, 2016
Device-to-Device (D2D) communications have emerged as a promising technology for the next generation mobile communication networks and wireless systems (5G). As an underlay network of conventional cellular networks (LTE or LTE-Advanced), D2D communications have shown great potential in improving communication capability, erasing communication delay ...

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 ...

Impact of Shadowing in D2D Communication

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Device-to-device (D2D) communication is expected to increase the coverage probability by coexisting along with the conventional cellular systems in 5G technology. As the user equipments are often held closer to the human body, D2D links experience shadowing modelled by the amp;#954;-amp;#956; shadowed fading model.

Layered D2D NOMA

China Communications, 2021
This paper investigates a layered power allocation (PA) non-orthogonal multiple access (NOMA) scheme for device-to-device (D2D) relaying networks, where the strategy of partial data transmission at relay nodes are adopted to improve the efficiency of resources. In addition, to satisfy different quality-of-service (QoS) requirements from multiple users,

Interference mitigation and D2D parameter estimation for distributed‐control D2D underlay systems

Transactions on Emerging Telecommunications Technologies, 2015
AbstractAlthough centralised‐control schemes for device‐to‐device (D2D) underlay communications can produce satisfactory results by efficiently managing the interference between cellular and D2D transmissions, they can become prohibitively complicated and may require a large amount of feedbacks from devices, because it is important to handle the inter ...

Power Allocation for D2D Communications With SWIPT

IEEE Transactions on Wireless Communications, 2020
Power allocation plays a vital role in coordinating interference between Device-to-Device (D2D) and cellular communications, and when power allocation meets simultaneous wireless information and power transfer (SWIPT), the energy efficiency of D2D communications can be significantly improved.
