Downlink Macrodiversity in Cellular Network - A Fluid Analysis

摘要

This paper proposes an analytical study of the downlink macrodiversity. Considering two macrodiversity links, we first show that the downlink macrodiversity induces a specific load in the cell. We establish an explicit expression of this one, and show that macrodiversity increases the total cell's load. The network's fluid analysis we propose enables to calculate the load of a cell and to quantify the impact of macrodiversity. We show that macrodiversity decreases the capacity of a cell. We generalize the analysis, considering a macrodiversity with a great number of base stations of the network.
