Initiated by MIIT since 2010.06

Technical discussion and studies began in 2010.12 tens of face to face meeting, Leading by CATR, CATT, CMCC, Huawei, ZTE, INNOFIDEI, China Unicom, China Telecom

Extended in IMT-Advanced Promotion Group 16 entities included: Government academy, Operators, Manufactures,

Colleges. Will be studied in the Requirement, Technologies and Standard group.

Government Project Planning “Enhancement Technologies for Indoor/Hotspot based on LTE-A”, 2012-2013 National

Science and Technology Major Project Lead by MOST and MIIT. CATR, CATT(Datang), CMCC, Huawei, ZTE, INNOFIDEI, Peking University, BUPT

Workshop with ERICSSON and Common Understanding It is important to ensure that radio-access technologies in 3GPP can operate efficiently

in local-area/low-mobility scenarios LTE evolution for the low-mobility/local-area scenario The operation on licensed spectrum with operators is necessary and has first priority .

As low priority, consider it can work on unlicensed spectrum as complement. For deployment or usage scenario, focus on operator deployment.

Workshop with Nokia/NSN and Common Understanding Common understanding with the scenarios and requirement. Standard development in 3GPP

Extended Spectrum Bands

1000 times of traffic can not be reached only be technical enhancement Spectrum suitable for mobile is limited(<3GHz) Indoor/Hotspot dominate the 80% of 1000 Short coverage/Low mobility requirement Wide bandwidth/High throughput requirement Avoid outdoor-indoor interference, easy to deployment and good performance

Extended band from cellular network to high spectrum band(>3GHz)
