Dynamic-TDD Interference Tractability Approaches and Performance Analysis in Macro-Cell and Small-Cell Deployments
Jalal Rachad, Ridha Nasri, Laurent Decreusefond
Meeting the continued growth in data traffic volume, Dynamic Time Division Duplex (D-TDD) has been introduced as a solution to deal with the uplink (UL) and downlink (DL) traffic a…
A 3D Beamforming Scheme Based on The Spatial Distribution of User Locations
Jalal Rachad, Ridha Nasri, Laurent Decreusefond
Multi-antenna technologies such as massive Multiple-Input Multiple-Output (massive MIMO) and beamforming are key features to enhance performance, in terms of capacity and coverage,…
3D Beamforming based Dynamic TDD Interference Mitigation Scheme
Jalal Rachad, Ridha Nasri, Laurent Decreusefond
Dynamic Time Division Duplexing (D-TDD) allows cells to accommodate asymmetric traffic variations with high resource assignment flexibility. However, this feature is limited by two…
Radio Resource Dimensioning with Cox Process Based User Location Distribution
Ridha Nasri, Jalal Rachad, Laurent Decreusefond
The upcoming fifth generation (5G) New Radio (NR) interface inherits many concepts and techniques from 4G systems such as the Orthogonal Frequency Division Multiplex (OFDM) based w…
Interference Analysis in Dynamic TDD System Combined or not With Cell Clustering Scheme
Jalal Rachad, Ridha Nasri, Laurent Decreusefond
Dynamic Time Division Duplex (TDD) has been introduced as a solution to deal with the uplink and downlink traffic asymmetry, mainly observed for dense heterogeneous network deploym…
How To Dimension Radio Resources When Users Are Distributed on Roads Modeled by Poisson Line Process
Jalal Rachad, Ridha Nasri, Laurent Decreusefond
Resources dimensioning aims at finding the number of radio resources required to carry a forecast data traffic at a target users Quality of Services (QoS). The present paper attemp…
