Microsoft C++ based system-level simulator is used to evaluate the performance gain and limitation of Type-1 relay and the consideration on the limitations to access link scheduling are considered.Abstract:
LTE-Advanced is the next major evolution step for E-UTRAN LTE in 3rd Generation Partnership Project (3GPP). One of the key technology enhancements in LTE-Advanced to fulfill the performance requirement and to improve the user experience at cell edge is wireless self-backhauling relay, so called "Type-1 Relay". In the recent 3GPP RAN plenary, Type-1 relay was approved as a work item in release 10. Type-1 relay is an in-band and half-duplex relay which means the access link and backhaul link operates in the same band and the transmission on access link and backhaul link are time multiplexed. In this paper, Type-1 relay is modeled with the realistic backhaul link and the consideration on the limitations to access link scheduling. Microsoft C++ based system-level simulator is used to evaluate the performance gain that brings by Type-1 relay, and also shows the limitation of Type-1 relay.read more
