A SINR-Based Synchronization Protocol for D2D Communications in Public Safety

A D2D-based Protocol for Ultra-Reliable Wireless Communications for Industrial Automation

As one indispensable use case for the 5G wireless systems on the roadmap, ultra-reliable and low latency communications (URLLC) is a crucial requirement for the coming era of wireless industrial automation. The key performance indicators for URLLC are in sharp contrast to the current broadband communications, since latency and reliability are paramount but high data rates are often not required...

Unsupervised LTE D2D - Case Study for Safety-Critical V2X Communications

This article explores the recent 3GPP LTE D2D rel. 14 Radio Resource Management specification to identify the challenges and evaluate the potentials of Unsupervised LTE D2D (mode 2) for Safety-critical V2X Communications. It also proposes two distributed resource allocation strategies for unlicensed band access. Complementary to DSRC/ITS-G5, unsupervised LTE D2D is an opportunity to provide red...

Recent Advances in 3GPP Rel-12 Standardization related to D2D and Public Safety Communications

The goal of this paper is to present advances on recent 3GPP standardization activities related to Device-to-Device (D2D) and public safety. The paper provides a clear 3GPP state of the art, including when the 3GPP work on D2D and public safety communications started. Finally, it presents important conclusions with respect to further 3GPP work on this topic.

A SINR Improvement Algorithm for D2D Communication Underlaying Cellular Networks

In this paper, we study the interference scenario where multiple Device-to-Device (D2D) pairs and one cellular use share the same spectrum resources, and propose a novel D2D signal-to-interference-plus-noise ratio (SINR) improvement algorithm called DSIA from the perspective of precoding and decoding. Numerical results show that in comparison with the traditional spectrum orthogonal scheme, the...
