Abstract :
LTE of the UMTS Terrestrial Radio Access and Radio Access Network is aimed at supporting high speed package data service. LTE constitutes a major step toward 4G network and supports both FDD mode and TDD mode. In this paper, we study the interference cases of LTE TDD system, especially the crossed timeslot interference (CTI) is discussed and evaluated in detail. According to the simulation assumption, the system performance of LTE TDD using three classic scheduling schemes with or without consideration of CTI is evaluated by system level simulation. We have developed the simulation platform for both uplink and downlink directions. Simulation results show that the throughput degrades significantly due to the CTI.
