  1. CJK-IMT28-027 Studies on Indoor/Hotspot Mobile Data Solutions Qin Fei (qinfei@catt.cn) CJK IMT #28 Xi’an, China June, 2nd-3rd , 2011

  2. Content Background Activities Solutions and Plan

  3. Background-Requirement • 1000x of mobile broadband data traffic in 10 years, 80% indoor/hotspot. • Economical, High throughput and bit rate, Good user experience. • Mobile(for Outdoor) + Local/Nomadic(for Indoor/Hotspot) solutions, in one SDO and industry alliance.

  4. Background-Future RAT 4G+ Higher SE wider bandwidth • Mobile • Local/Nomadic Access 4G Economical solution high performance-price ratio 3G Specific scenario Specific service 2G High mobility Various QoS Large coverage Indoor scenario IP based data Future network will be organic integration of cellular mobile network and hotspot coverage 4

  5. Background-Indoor/Hotspot Scenarios Low mobility/nomadic • Low cost • Local/Nomadic Access • Optimized RF/PHY/MAC • High performance • Extended band • PHY/MACenhancement for indoor • Good UE experience • Tight Interworking with mobile • Service Continuity • Long battery life High bit rates/Large volume IPdata dominate Requirement Short coverage/high density Stable/rich scattering

  6. Content Background Activities Solutions and Plan

  7. Activates • 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.

  8. Activates • 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

  9. Content Background Activities Solutions and Plan

  10. Solutions and Plan • 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)

  11. Solutions and Plan • LTE/LTE-A Based Local Area Access

  12. Solutions and Plan • LTE/LTE-A Femto Enhancement

  13. Solutions and Plan • Others • New/Optimized PHY/MAC design for Indoor/Hotspot scenarios • Simplified RF design for cost efficient • Wide bandwidth for high speed • QoS enhancement for high speed data • L2 Optimize for data services • …

  14. Solutions and Plan M.1036 3.4-3.6GHz IMT.Update WRC-12 WI New bands >3GHz WRC-15/16

  15. Solutions and Plan System architecture PCG SA2 System requirement RAN1 PHY SA SA1 RAN2 R12 Protocol RAN • Scenario • requirement RAN3 Interface RAN4 RF …… Requirement Definition System Design （SI&WI） Setup Item （2011.8~ 2012.Q3） （2012.Q3 ~ ）
