Multi-Channel Access Solutions for 5G New Radio
Nurul Huda Mahmood, Daniela Laselva, David Palacios +4
5G New Radio paves the way for introducing novel multi-service radio resource management solutions tailored for enhanced Mobile Broadband and Ultra-Reliable Low Latency Communicati…
Analysis of Latency and MAC-layer Performance for Class A LoRaWAN
R. B. Sørensen, D. M. Kim, J. J. Nielsen +1
We propose analytical models that allow us to investigate the performance of long range wide area network (LoRaWAN) uplink in terms of latency, collision rate, and throughput under…
An Enhanced Access Reservation Protocol with a Partial Preamble Transmission Mechanism in NB-IoT Systems
Taehoon Kim, Dong Min Kim, Nuno Pratas +2
In this letter, we propose an enhanced Access Reservation Protocol (ARP) with a partial preamble transmission (PPT) mechanism for the narrow band Internet of Things (NB-IoT) system…
Full Duplex Emulation via Spatial Separation of Half Duplex Nodes in a Planar Cellular Network
Henning Thomsen, Dong Min Kim, Petar Popovski +2
A Full Duplex Base Station (FD-BS) can be used to serve simultaneously two Half-Duplex (HD) Mobile Stations (MSs), one working in the uplink and one in the downlink, respectively.…
Assessment of LTE Wireless Access for Monitoring of Energy Distribution in the Smart Grid
Germán C. Madueño, Jimmy J. Nielsen, Dong Min Kim +3
While LTE is becoming widely rolled out for human-type services, it is also a promising solution for cost-efficient connectivity of the smart grid monitoring equipment. This is a t…
CoMPflex: CoMP for In-Band Wireless Full Duplex
Henning Thomsen, Petar Popovski, Elisabeth de Carvalho +3
In this letter we consider emulation of a Full Duplex (FD) cellular base station (BS) by using two spatially separated and coordinated half duplex (HD) BSs. The proposed system is…
Reliable Uplink Communication through Double Association in Wireless Heterogeneous Networks
Dong Min Kim, Petar Popovski
We investigate methods for network association that improve the reliability of uplink transmissions in dense wireless heterogeneous networks. The stochastic geometry analysis shows…
A Tractable Model of the LTE Access Reservation Procedure for Machine-Type Communications
Jimmy J. Nielsen, Dong Min Kim, Germán C. Madueño +2
A canonical scenario in Machine-Type Communications (MTC) is the one featuring a large number of devices, each of them with sporadic traffic. Hence, the number of served devices in…
Exploiting Regional Differences: A Spatially Adaptive Random Access
Dong Min Kim, Seong-Lyun Kim
In this paper, we discuss the potential for improvement of the simple random access scheme by utilizing local information such as the received signal-to-interference-plus-noise-rat…
An Iterative Algorithm for Optimal Carrier Sensing Threshold in Random CSMA/CA Wireless Networks
Dong Min Kim, Seong-Lyun Kim
We investigate the optimal carrier sensing threshold in random CSMA/CA networks considering the effect of binary exponential backoff. We propose an iterative algorithm for optimizi…
