Unformatted text preview: Technical Overview of 3GPP LTE May 18, 2008 Hyung G. Myung ([email protected]) Technical Overview of 3GPP LTE | Hyung G. Myung 1 Cellular Wireless System Evolution Cellular Wireless System Evolution Cellular Wireless System Evolution Cellular Wireless System Evolution • 1G (Early 1980s) – Analog speech communications. – Analog FDMA. – Ex: AMPS • 2G (Early 1990s) – Digital modulation of speech communications. – Advanced security and roaming. – TDMA and narrowband CDMA. – Ex: GSM, IS-95 (cdmaOne), and PDC • 3G (Late 1990s) – Global harmonization and roaming. – Wideband CDMA – Ex: UMTS, cdma2000, and TD-SCDMA Introduction Technical Overview of 3GPP LTE | Hyung G. Myung 2 Beyond 3G Beyond 3G Beyond 3G Beyond 3G • International Mobile Telecommunications (IMT)-2000 introduced global standard for 3G. • Systems beyond IMT-2000 (IMT-Advanced) is set to introduce evolutionary path beyond 3G. – Mobile class targets 100 Mbps with high mobility and nomadic/ local area class targets 1 Gbps with low mobility. • 3GPP and 3GPP2 are currently developing evolutionary/ revolutionary systems beyond 3G. – 3GPP Long Term Evolution (LTE) – 3GPP2 Ultra Mobile Broadband (UMB) • IEEE 802.16-based WiMAX is also evolving towards 4G through 802.16m. Introduction Technical Overview of 3GPP LTE | Hyung G. Myung 3 3GPP Evolution 3GPP Evolution 3GPP Evolution 3GPP Evolution • Release 99 (Mar. 2000): UMTS/WCDMA • Rel-5 (Mar. 2002): HSDPA • Rel-6 (Mar. 2005): HSUPA • Rel-7 (2007): DL MIMO, IMS (IP Multimedia Subsystem), optimized real-time services (VoIP, gaming, push-to-talk). • Long Term Evolution (LTE) – 3GPP work on the Evolution of the 3G Mobile System started in November 2004. – Standardized in the form of Rel-8. – Spec finalized and approved in January 2008. – Target deployment in 2010. – LTE-Advanced study phase in progress. Introduction Technical Overview of 3GPP LTE | Hyung G. Myung 4 3GPP2 Evolution 3GPP2 Evolution 3GPP2 Evolution 3GPP2 Evolution • CDMA2000 1X (1999) • CDMA2000 1xEV-DO (2000) • EV-DO Rev. A (2004): VoIP • EV-DO Rev. B (2006): Multi-carrier • Ultra Mobile Broadband (UMB) , f.k.a. EV-DO Rev. C – Based on EV-DO, IEEE 802.20, and FLASH-OFDM – Spec finalized in April 2007. – Commercially available in early 2009. Introduction Technical Overview of 3GPP LTE | Hyung G. Myung 5 IEEE 802.16 Evolution IEEE 802.16 Evolution IEEE 802.16 Evolution IEEE 802.16 Evolution • 802.16 (2002): Line-of-sight fixed operation in 10 to 66 GHz • 802.16a (2003): Air interface support for 2 to 11 GHz • 802.16d (2004): Minor improvements to fixes to 16a • 802.16e (2006): Support for vehicular mobility and asymmetrical link • 802.16m (in progress): Higher data rate, reduced latency, and efficient security mechanism Introduction Technical Overview of 3GPP LTE | Hyung G. Myung 6 Requirements of LTE Requirements of LTE Requirements of LTE Requirements of LTE • Peak data rate – 100 Mbps DL/ 50 Mbps UL within...
