Modeling and Analysis of MPTCP Proxy-based LTE-WLAN Path Aggregation
Long Term Evolution (LTE)-Wireless Local Area Network (WLAN) Path Aggregation
(LWPA) based on Multi-path Transmission Control Protocol (MPTCP) has been under
standardization procedure as a promising and cost-efficient solution to boost
Downlink (DL) data rate and handle the rapidly increasing data traffic. This
paper aims at providing tractable analysis for the DL performance evaluation of
large-scale LWPA networks with the help of tools from stochastic geometry. We
consider a simple yet practical model to determine under which conditions a
native WLAN Access Point (AP) will work under LWPA mode to help increasing the
received data rate. Using stochastic spatial models for the distribution of
WLAN APs and LTE Base Stations (BSs), we analyze the density of active
LWPA-mode WiFi APs in the considered network model, which further leads to
closed-form expressions on the DL data rate and area spectral efficiency (ASE)
improvement. Our numerical results illustrate the impact of different network
parameters on the performance of LWPA networks, which can be useful for further
performance optimization.Comment: IEEE GLOBECOM 201
Downlink and Uplink Decoupling: a Disruptive Architectural Design for 5G Networks
Cell association in cellular networks has traditionally been based on the
downlink received signal power only, despite the fact that up and downlink
transmission powers and interference levels differed significantly. This
approach was adequate in homogeneous networks with macro base stations all
having similar transmission power levels. However, with the growth of
heterogeneous networks where there is a big disparity in the transmit power of
the different base station types, this approach is highly inefficient. In this
paper, we study the notion of Downlink and Uplink Decoupling (DUDe) where the
downlink cell association is based on the downlink received power while the
uplink is based on the pathloss. We present the motivation and assess the gains
of this 5G design approach with simulations that are based on Vodafone's LTE
field trial network in a dense urban area, employing a high resolution
ray-tracing pathloss prediction and realistic traffic maps based on live
network measurements.Comment: 6 pages, 7 figures, conference paper, submitted to IEEE GLOBECOM 201
