Railway Network Evolution Why it is urgent to wait for 5G?
The 3GPP 5G standard is almost ready. If its first phase, completed in 2018, allows this standard to claim its 5G status, it will become totally standardized after the second round of standardization completed at the end of 2019. The 5G sta...
A Frame Design for MIMO UW based Systems: Overhead Analysis & Channel Estimation
In this paper, we extend the conventional single-input-single-output unique word (UW) based frame designs to MIMO applications with spatial multiplexing. Considering a doubly-dispersive channel where the channel is varying both in time and ...
Dielectric Material Characterization for 5G Propagation Modelling
In this paper, a technique for the characterization of the complex permittivity of flat material panels is presented. Using broadband horn antennas and a simple measurement process, the permittivity and dielectric loss tangent of the materi...
Tractable Scheduling Algorithms for Self-Backhaul in 5G Networks
We consider the problem of scheduling 5G wireless networks with self-backhaul. The key difficulty is coordinating the transmissions on the backhaul and access links since a node cannot transmit and receive at the same time. A well-known sol...
Impact of Bandwidth Part (BWP) Switching on 5G NR System Performance
Bandwidth Parts (BWPs) is a 5G NR feature introduced in 3GPP Release 15 for dynamically adapting the carrier bandwidth and numerology in which a UE operates. BWP allows supporting multiple services per carrier, e.g. eMBB and mMTC. Although ...
Minimizing Uplink Delay in Delay-Sensitive 5G CRAN platforms
In this paper, we consider the problem of minimizing the uplink delays of users in a 5G cellular network. Such cellular network is based on a Cloud Radio Access Network (CRAN) architecture with limited fronthaul capacity, where our goal is ...
Leveraging on Source Routing for Scalability and Robustness in Datacenters
The transition towards 5G leads to higher in-network processing demands, which, in turn, raise more severe dataplane requirements, e.g., in terms of datacenter switch forwarding state. Since legacy switches coupled with layer-2/3 forwarding...
DF4CRAN: Dataflow Framework for Cloud-RAN Signal Processing
Nowadays mobile operators face several challenges because of huge growth of internet traffic usage. Cloud Radio Access Network(C-RAN) was proposed as a solution for this problem. There are already many implementations of C-RAN but they are ...
Definition and Evaluation of Latency in 5G: A Framework Approach
Latency as a key performance indicator (KPI) of 5G communication has attracted a significant amount of efforts from both industry and academia to provide the enhanced technology solution to meet the requirement of low latency from the diver...
Implementation and Performance Measurement of Flexible Radix-2 GFDM Modem
Recent researches indicate that generalized frequency division multiplexing (GFDM) can be regarded as a physical layer waveform core. With proper configuration, it can be used to generate different type of the state of the art waveforms. Th...
