Requirements and Evaluation on mmWave Radio Interface Technology (RIT) for IMT-2020 (5G)

摘要

International Telecommunication Union (ITU) embarked on a programme to develop IMT-2020 as a new international standard name for fifth generation mobile systems and has set the minimum performance requirements and evaluation methodologies of IMT-2020. IMT-2020 systems will be the mobile systems that include new radio interface which support the new capabilities of systems beyond IMT-Advanced. In particular, the data rate of IMT-2020 is expected to be 10 times to 20 times larger compared to IMT-Advanced for enhanced Mobile Broadband. In order to achieve this requirement, mmWave band and micro-cell deployment are essential. In this paper, we proposed candidate technology for IMT-2020 and consider evaluation results which are theoretically expected data rate and system level simulation for spectral efficiency. When the micro-cells in indoor hotspot are deployed, the expected data rate user spectral efficiency with mmWave radio interface technology through 12 TRxP and 36 TRxP has met with IMT-2020 requirement. The evaluation of dense urban eMBB scenario should be needed for proofing outdoor performance with mmWave in the next stage towards 5G reality.
