Abstract :
Mobile Internet and Internet of Thing (IoT) have been widely recognized as the two major driven forces of next generation mobile systems (IMT-2020 or 5G). Key performance indicators (KPI) of 5G are identified to satisfy the needs of these applications. It is analyzed that a new waveform design with large bandwidth at high frequency for small cell is expected for some critical KPIs. In this paper, perspectives on new waveform design for 5G small cell are presented. Specifically, the design principles for transmission time interval (TTI), system bandwidth, the subcarrier spacing, the cyclic prefix (CP), guard period (GP) and frame structure are discussed. The feasible range of numerology of the new waveform considering efficiency, flexibility and backward compatibility jointly is derived. Finally, an exemplary numerology for 5G small cell is given.
