WM-SIM is a standard compliant link-level simulation environment for the 3GPP Long Term Evolution (LTE) technology. The simulator has been developed by the Communications Engineering Research Group at the Universidad de Málaga (Spain). Compared to previous version, new features regarding heterogeneous networks have been added. Specifically, regular (hexagonal) and irregular (spatial random) deployments can be used for macro and small base stations. Biased association criteria for the Downlink (DL) coupled or decoupled to that for the Uplink (UL) might be dessigned. DL power setting and UL fractional power control and Interference mitigation through Fractional Frequency Reuse (FFR) could also be simulated.
