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.

Enabling D2D communications in LTE networks
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013Device-to-Device (D2D) communications provide the means to users of cellular networks for spatially reusing licensed spectrum by establishing direct connections. Considering the benefits for operators and consumers, a plethora of resource and interference management approaches in the literature deal with parallel cellular and D2D transmissions. However,

Operational region of overlay D2D communications
2015 IEEE International Conference on Communications (ICC), 2015An 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), 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 ...

Assessing Coverage and Throughput for D2D Communication
2018 IEEE International Conference on Communications (ICC), 2018In 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 ...

D2D cooperative communications for disaster management
2017 24th International Conference on Telecommunications (ICT), 2017In 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 ...
