A Simulation Implementation of the LTE-Uu Interface Datalink Layer in OMNeT++

The 3rd Generation Partnership Project (3GPP)’s Long Term Evolution (LTE) standards define the next major step in the evolution of cellular systems towards higher data rates, low latency, and greater spectral efficiency. This occurs in the context of a System Architecture Evolution (SAE) that specifies a packetswitched IP architecture for both voice and data transmission. We present a simulation implementation of a key component of the overall LTE-SAE: the L2 (Datalink) layer of the LTE-Uu interface between mobile User Equipment (UE) and a base station eNodeB. The simulation is developed for the INET Framework of OMNeT++4.0, an open-source computer-network simulation environment, and implements the Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Medium Access Control (MAC) layers of the LTE-Uu. The implementation is extensible, and is intended to serve as a publicly-available, opensource platform for further simulation development of various aspects of LTE-SAE.
