Transmission Capacity Of D2D Communication Under Cellular Networks

摘要

Device-to-Device communication is introduced in cellular system to make full use of the spectrum resources. In order to study the D2D transmission capacity when the D2D multiplexing orthogonal and non-orthogonal of the resource sharing mode, the paper studies D2D system interference in LTE cellular networks. Due from cellular edge user vulnerability, D2D reuse non-orthogonal resources will bring a larger outage probability. In this paper, The D2D reuse resources of cellular users near the base station, which bring greater improvements in the outage probability of cellular users, and then calculated the outage probability and the transmission capacity of D2D in cell system. Found through simulation comparison, It is proximate between theoretical calculations and simulation values when multiplexed the preferred regional cellular user resources.
