TLDR
In this paper, the interference cases of LTE TDD system, especially the crossed timeslot interference (CTI), are discussed and evaluated in detail and 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.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.read more

Multiplexing ues with different tdd configurations and some techniques to mitigate ue-to-ue and base station-to-base station interference
TL;DR: In this paper, a method of wireless communication includes determining a set of subframes with a reduced likelihood of being received as uplink transmissions of a first user equipment (UE) by scheduling uplink control information (UCI) on subframes other than the determined set.
