Scope: 3GPP LTE radio access is one candidate for the radio access technology to be used for the Future Rail Mobile Communications System (FRMCS). In the present document@ the term FRMCS refers -unless stated otherwise- to the radio part of the communication system. The present document is intended to: ? Define the simulation parameters relevant to rail environment relating to 3GPP LTE radio performance. This includes in particular operating frequency bands@ bandwidths@ deployment scenario (inter-site distance)@ and antenna characteristics@ transmit powers and channel models@ along with relevant metrics to be evaluated. ? Collect and analyse the simulation results of an LTE system in the rail environment. ? Identify limitations of an LTE system in the rail environment. Radio performance evaluation of an LTE system could be done by simulation@ through software and processing resources only@ or through a test bench incorporating pieces of equipment emulating parts of the chain@ e.g. the RF. In both cases@ it is important to align the parameters and the assumptions made in the simulation and in the evaluation chain to be able to reflect better a deployment in a rail environment@ and to better compare and understand the simulation and the evaluation results.
