UAI CAS Unified Frame Structure for Various Services Optimized Frame Structure by UFS with Flexible Parameters and Configurations • For majority eMBB services, normal frame TTI length should meet the timing and bandwidth requirements • For mission critical uRLLC services, frame TTI length can be reduced to speed up response time, shorten overall latency • For majority mMTC services, when massive connections are required, frame TTI length can be increased to accommodate large number of devices connected simultaneously • Subcarrier spacing is also the parameter for consideration 6
UAI CAS Spectrum Challenges for 5G 1. Over 30 Spectrum Bands for LTE Deployment – Major LTE frequency bands • 700MHz/800MHz/900MHz/1.8GHz/2.1GHz/2.3GHz/2.6GHz • Channel bandwidths: 10MHz/20MHz/others NB-LTE • Possible spectrum re-farming, potential band interference – Smartphone design challenges • GSM/CDMA, UMTS, WiFi, Bluetooth and GPS radio/ band combinations • Challenges of ecosystem & economies of scale 2. FDD/TDD Challenges – Different Carrier Aggregation proposals – Overall ecosystem & global inter-operability between networks 7
