Abstract:
3GPP is currently studying the improvement on the LTE eMBMS system to provide more capabilities and flexibilties on delivering multicast/broadcast services using the LTE infrastructure. This paper investigates the performance of an improved LTE eMBMS system using layered-division-multiplexing (LDM) technology and longer cyclic prefix (CP). The link-layer performance of using two-layer LDM in eMBMS system is first investigated with extensive computer simulations. Coverage analysis is then conducted on future eMBMS services with different cyclic prefix (CP) lengths, to allow more efficient deployment of multicast/broadcast single-frequency-network (MBSFN) for different cell sizes. The coverage performance is then used to demonstrate the capability of the improved eMBMS system with LDM to simultaneously deliver high-definition (HD) indoor/mobile services and ultra-HD fixed services targeting receivers with rooftop antennas.
