Measuring and mapping multi-user cell-virtualization performance in a cloud-RAN small cell network

This paper describes the first series of measurements to characterize and map spatial spectral reuse and total system throughput as a function of the location of multiple users within the coverage area of the “OneCell” virtualized Cloud-RAN smallcell deployment. The measurements demonstrate that the adaptive frequency reuse algorithm which creates virtual cells from the set of all active users each 1 millisecond TTI provides multiple units of reuse within the single borderless cell. The transition from one unit of reuse to two full units of reuse was observed. Total system throughput approaching 240 MBPS in a 20 MHz allocation was attained with two UE's.
