3GPP Long Term Evolution (LTE) and System Architecture Evolution (SAE)

3GPP Standards study item since Dec 2004, Feasibility Study to be completed mid 2006, Standardization as a Rel’8 or later feature

LTE is a 3GPP initiative to develop a new RAN/air-interface to

– Support high efficiency OFDMA carriers with scalable bandwidths of 1.25-20 MHz

– Provide significantly improved peak and cell edge data throughputs:

– Towards 100 Mb/s Downlink, 50 Mb/s Uplink,

– 2-4 times better spectral efficiency over HSDPA/HSUPA (in bits/s/Hz/cell)

– Support smaller frame durations in order to achieve reduced latencies less than 10 ms

– Support for advanced antenna schemes (e.g. SDMA) and MIMO

– Support for wide range of QoS and Mobility

SAE is a 3GPP initiative to develop a new flat(ter) network architecture (…..2008)

– Simpler system (than UMTS), purely packet-oriented

– Reduced number/type of nodes for lower transport delay….BSR is a major step towards flat IP

– Scalability to support the high data rates required for LTE

Goal of 3GPP LTE/SAE is to Define a New RAN/Air-Interface to Better Deliver Broadband and Real Time Packet Switched Services over a New Flat(ter) Network Architecture

– Strictly Backwards Compatible Mode • Based on 1.25 MHz multi-carrier• Provides full backwards compatibility with Rev. 0/A/B

– Loosely Backwards Compatible Mode• New 1.25-20 MHz OFDMA/CDMA carriers (can do a mix of broadband and multi-carrier)• TDD, FDD and Flex FDD duplexing

Multi-Antenna Technology Support– Spatial Division Multiple Access (SDMA) provides near doubling of spectral efficiency with 4-branch

Tx/Rx– Spatial Multiplexing MIMO on the FL for hot spots/indoor deployment provides peak rate

improvement proportional to the number of Tx/Rx antennas.Inter-cell co-ordination for further improvements in cell-edge user performanceStandardized technology-agnostic Flat IP architecture

�Initial 3G systems (EDGE, R’99 UMTS, 3G1x) focused on voice, yielding modest data performance benefits

�Evolved 3G or 3G+ systems (HSDPA/E-DCH, 1xEV-DO/DV) provided significant data performance benefits

�HSDPA, 1xEV-DO and 802.16 downlink have similar spectral efficiency performance

�For MIMO systems:– SM/BLAST offers the best peak data rates,

– SDMA offers the best spectral efficiency.

�We see Strong potential of OFDM influencing where WiMAX goes

�Time-to-market advantage of 3G will make WiFi / WiMAX complementary�for coverage complement / backhaul applications

�the potential of mobile WiMAX hinges on the success of existing 3G technologies

�We anticipate Mobile broadband Access will be cellular based

Lucent Flat-IP Mobile Architecture Solution Key Value PropositionLower cost wireless network

– leverages fewer wireless-specific elements (CapEx reduction). • reduce CapEx spend by approximately 30% compared to a traditional UMTS network

– consolidates many functions into BSR (BTS, RNC, SGSN & GGSN)– Investment protection through increasing use of IP protocols and technologies that

makes it future proof for IMS network

Higher capacity wireless network– high capacity backhaul– Leverages low cost of ethernet switching– air interface performance enhancements (UMTS/HSDPA & HSUPA)

Architecture simplicity and operations savings– consistent architecture for macro/micro/WiMax/WiFi access– fewer wireless-specific elements & interfaces to deploy, manage

Converged services enabling– limits extent of wireless specific infrastructure to access– promotes consistency of multiple wireless & wireline access types, and convergence

via access-agnostic IMS services

Lucent’s innovative flat BSR-based Access Architecture

has the potential to host today’s and future heterogeneous, converged wireline/wireless

solutions, including simplified support for multimedia multicast solutions
