12 LTE (Long Term Evolution) - Standardization Work on LTE began in 2004 Requirements of LTE (TR25.913) are approved at 3GPP TSG RAN #28 meeting in June, Requirements: Reduce C-plane latency: idle to active < 100 ms Peak data rate e.g. 100 Mbps (downlink) and 50 Mbps (uplink) Increase data rate in cell edge Scalable bandwidth to support multiple bandwidths Spectrum efficiency (e.g. 2~4 times than Rel-6, i.e. HSPA) Optimized for low mobility but also support high mobility Operation in paired and unpaired spectrum (i.e. FDD and TDD) Efficient support of the various types of services, especially from the PS domain (e.g. Voice over IP, Presence) Interworking with 3GPP system and non-3gpp system

13 LTE (Long Term Evolution) Standardization An official work item started in 2006 The first release of LTE specifications (Release 8) are released in March, Dec or 2009 March versions are considered stable for implementation Positioning (LCS/LPP) and MBMS are added in LTE specifications in 3GPP release 9

16 LTE (Long Term Evolution) Standardization Weakness of Taiwan company joining standardization activities: Meeting skills on argument and discussion Technical skills on leading technologies Not capable of predicting the direction Always be a follower No much R&D resource is put in standardization <= may be due to ODM Datang has more than 200 engineers in 3GPP standardization Huawei has at least 10 delegates in each RAN2 meeting and 20 delegates in each RAN1 meeting

22 LTE Deployment Status Operator Strategy Data-only services on LTE Quickly deployment of LTE because of no voice support Data card, wireless router/gateway supporting single mode or multimode (LTE/3G/2G) Data-only services on LTE with 2G-3G voice Voice is supported by CS fallback to GSM/UMTS/CDMA2000 Mobile phone supporting multi-mode (LTE/3G/2G) Voice and data services on LTE. Voice is supported by IMS Mobile phone supporting multi-mode (LTE/3G/2G) SRVCC may be required to support handover IMS call in LTE to CS call in 2G/3G

23 LTE Deployment Status Operator Strategy Operator may offer LTE data service only in the initial deployment (for data card only) Operator may offer LTE data services with voice services on the 2G-3G network first and later migrate their voice traffic to LTE. Alternatively, operator may decide to jump straight to the third strategy, offering all voice and data services on LTE without ever deploying the first two options.
