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,

Feasible D2D communication distance in D2D-enabled cellular networks
2014 IEEE International Conference on Communication Systems, 2014In D2D-enabled cellular networks, data communications between user equipments (UEs) can be completed by two modes: the cellular mode and the D2D mode where UEs bypass the base station and directly communicate with each other. Usually the transmission mode is selected based on the distance between the UEs.

A Design of D2D-Clustering Algorithm for Group D2D Communication
2020Due to the characteristics of low latency and proximity discovery, D2D communication is considered to have an inherent advantage in supporting Internet-of-Vehicles (IoV) service. In this paper, considering that vehicular users can detect neighbor nodes in adjacent areas which are able to maintain high reliable communication with themselves, a novel ...

Block-D2D: Blockchain-enabled Cooperative D2D-assisted Fog Computing Scheme under Imperfect CSI
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021Fog computing (FC) supports cloud computing services at the edge of the device for more secure and reliable access and processing of the stored data. However, it is beneficial for time-sensitive applications, where the required delay is minimum, but not well suited for mission-critical applications, where the required delay is negligible.

D2D CSI feedback for D2D aided massive MIMO communications
2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016We 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 ...
