On the sojourn time of a batch in the Processor Sharing Queue
Fabrice Guillemin, Alain Simonian, Ridha Nasri +1
In this paper, we analyze the sojourn of an entire batch in a processor sharing processor queue, where geometrically distributed batches arrive according to a Poisson…
A New Linear Inversion Formula for a class of Hypergeometric polynomials
Ridha Nasri, Alain Simonian, Fabrice Guillemin
Given complex parameters , , , and , consider the infinite lower triangular matrix with elements $$ A_{n,k}(x,ν;α,β,γ) =…
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…
