Modeling and Simulation Analysis of the Physical Sidelink Shared Channel (PSSCH)

摘要

This paper examines the performance of the Long Term Evolution (LTE) Physical Sidelink Shared Channel (PSSCH) in out-of-coverage (OOC) device- to-device (D2D) communication scenarios. We develop a closed form expression for the distribution of the number of User Equipments (UEs) that successfully decode a message sent on the PSSCH, given the number of UEs that received the transmitter's Sidelink Control Information (SCI) message over the Physical Sidelink Control Channel (PSCCH). We validate our results using Monte Carlo simulations of the PSSCH and network simulations in ns-3, and discuss some of the effects of system parameters on performance.
