  "abstract": "<p>In LTE-Advanced networks, the steady demand\u00a0for higher data rates by users is met through several techniques.\u00a0One of the most promising solutions is CoMP (Coordinated\u00a0MultiPoint), which allows the involvement of multiple eNB in\u00a0the transmission and reception process with a marked increase\u00a0in throughput for users at the edge of cells. While downlink\u00a0CoMP has been the focus of many works in the literature,\u00a0in this paper we examine Uplink CoMP with Coordinated\u00a0Scheduling in Heterogeneous Networks running LTE-A. We\u00a0investigate its system-level performance through simulation in\u00a0various realistic scenarios with frequency-selective Rayleigh\u00a0fading. Specifically, we are interested in comparing the performance\u00a0of Uplink CoMP with different cell types as well\u00a0as different user participation to CoMP transmissions. Our\u00a0simulation results confirm that edge users benefit from Uplink\u00a0CoMP, although the overall throughput decreases. In order to\u00a0mitigate the latter effect, we introduce two new parameters, called CoMP margin and CoMP Pool Percentage (CPP), and\u00a0provide guidelines for their effective use.</p>",
