Mobile User Capacity Analysis of LTE-A Systems Based on Field Measurement Data

Abstract

In order to analyze the mobile user capacity supportable by a cell in LTE-A systems, we propose a methodology of combining a mathematical model and field measurement data. One important phenomenon considered by the proposed model is that the informations of resource assignment for the both downlink and uplink are transmitted on the same Physical Downlink Control Channel (PDCCH), i.e., the both downlink and uplink controls share the same PDCCH resource which may induce congestions. We perform field measurement on LTE-A cells to collect measurement data to support the parameters utilized by the proposed model. Through comparing the numerical results and the data from field measurement, we confirm the accuracy of the proposed mathematical model. © 2019 IEEE.
