5 HSPA Evolution (HSPA+) Required by operators to keeping enhancement to HSPA technology with a low cost Exploit the full potential of a CDMA approach before moving to an OFDM platform in 3GPP LTE Achieve performance close to LTE in 5 MHz of spectrum Reduced latency To 25 ms round-trip times between UE and BS, and To < 200 ms transition times from inactive to active

HSPA) Q2, 2010: 530 million => 3GPP technologies are the most successful wireless technologies in the world! Source: GSA (the Global mobile Suppliers Association), Mobile Broadband Status August 2010

11 Success of 3GPP Technologies HTC products First GPRS smart phone launched in 2002 First EDGE smart phone launched in 2005 First WCDMA (R99) smart phone launched in 2005 First HSDPA (Rel-5) smart phone launched in 2006 First HSUPA (Rel-6) smart phone launched in 2008 First HSPA+ (Rel-7) smart phone launched in 2010

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

15 LTE (Long Term Evolution) Standardization HTC have joined 3GPP LTE standardization work since May 2008 Working groups joined by HTC: RAN WG1 & WG2 CT WG1 SA WG2

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

17 LTE (Long Term Evolution) Feature and Function Downlink: OFDMA Uplink: Single Carrier (SC)-FDMA Sub-carrier: 15 KHz Flexible bandwidth: 1.4 ~ 20 MHz (1.4, 3, 5, 10, 15, 20) 72 sub-carriers for cell operation in minimum transmission bandwidth (i.e. 1.4 MHz) MIMO: max 4 x 4 (i.e. 4 antenna), DL only Modulation: QPSK, 16QAM and 64 QAM

18 LTE (Long Term Evolution) Feature and Function Maximum data rate: DL: 300 Mbps UL: 75 Mbps TTI (Transmission Time Interval): 1 ms <= reduce latency Flatter architecture <= reduce latency UMTS: CN, RNC, Node B LTE: CN, enode B Packet switch only GSM/UMTS support both Circuit Switch and Packet Switch Interworking with 2G/3G/CDMA Home enode B support (i.e. femto cell)

19 LTE (Long Term Evolution) UE Category (DL) UE Category (Downlink) Maximum number of DL-SCH transport block bits received within a TTI Maximum number of bits of a DL-SCH transport block received within a TTI Maximum number of supported layers for spatial multiplexing in DL (i.e. number of antenna) Category Category Category <= Most UEs support this category Category Category Source: 3GPP TS

20 LTE (Long Term Evolution) UE Category (UL) UE Category (Uplink) Maximum number of bits of an UL- SCH transport block transmitted within a TTI Support for 64QAM in UL Category No Category No Category No Category No Category Yes Source: 3GPP TS

21 LTE Deployment Status 101 LTE network commitments in 41 countries TeliaSonera commercially launch LTE in Stockholm, Sweden Data-only service for data card 19 LTE networks are expected to be in commercial service by end 2010 or 2011 Verizon Wireless Vodafone DE NTT DoCoMo Source: GSA (the Global mobile Suppliers Association), Mobile broadband status August 2010

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.

24 LTE - Advanced Carrier Aggregation (CA) Maximum five Rel-8 20 MHz carriers aggregated to support maximum 100 MHz bandwidth Contiguous or non-contiguous carriers can be aggregated Higher order MIMO DL :8x8, UL: 4x4 LTE-Advanced system supporting CA and MIMO DL data rate up to 1Gbps, UL data rate up to 500 Mbps LTE-Advanced meet ITU-R 4G requirement LTE and WiMAX 16e are not 4G because they don t meet ITU-R 4G requirement

25 LTE - Advanced Item Spectrum Allocation IMT-Advanced Requirement Up to 40 MHz LTE-Advanced Projected Capability Up to 100 MHz Latency User Plane 10 ms 10 ms Latency Control Plane 100 ms 50 ms Peak Spectral Efficiency DL 15 bps/hz 30 bps/hz Peak Spectral Efficiency UL 6.75 bps/hz 15 bps/hz Average Spectral Efficiency DL 2.2 bps/hz 2.6 bps/hz Average Spectral Efficiency UL 1.4 bps/hz 2.0 bps/hz Cell-Edge Spectral Efficiency DL 0.06 bps/hz 0.09 bps/hz Cell-Edge Spectral Efficiency UL 0.03 bps/hz 0.07 bps/hz

26 LTE - Advanced Relay function Improve coverage to have better in-building penetration, better signal quality and user rates will be much improved LTE-Advanced will be defined in 3GPP Release 10 Stage-1: feature study starts in 2008 Stage-2: functionalities lock down in Dec, 2010 Stage-3: LTE-Advanced specifications will be completed in 2011 LTE-Advanced will be deployed soon once LTE is deployed widely Similar to WCDMA to HSPA
