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

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
