TD-SCDMAShort-term Evolution —— N-Frequency Cell Solution • Overcome the following problems in multiple-cell solution for improving capacity in TD-SCDMA: • The difficulties in cell search • The complexity in UE measurements • The problem in handover • System inefficiency • Implementation of N-frequency cell • Multiple frequency bands are configured in one cell • A master frequency band is configured • DwPTS and P-CCPCH are only configured for master band

  8. TD-SCDMAShort Term Evolution —— MC-HSDPA N-frequency cell＋HSDPA Multi-carrier HSDPA • HSDPA • N-frequency cell • Multiple frequency bands are configured for one logical cell • Facilitate to multiple frequency bands combining for HSDPA • Multi-carrier HSDPA is a combination of N-frequency cell and HSDPA • Higher peak data rate（N*2.8Mb/s） • More suitable for packet services

  9. TD-SCDMAShort Term Evolution —— MC-HSDPA

  10. TD-SCDMAShort Term Evolution —— MC-HSDPA Multi-Carrier HSDPA Architecture

  11. TD-SCDMAShort Term Evolution —— MC-HSDPA Principles on multi-carrier HSDPA Standardization • Air interface shall keep compatible with N-frequency cell solution in CCSA TD-SCDMA stage I; • Physical layer: channel structure of HS-SCCHand HS-SICH is same to that for single-carrier HSDPA system ； • MAC layer: segmentation/combining. • UE Capability: adding UE multi-carrier HSDPA capability indicator in corresponding field. • The multi-carrier HSDPA is based on 3GPP R5 HSDPA, but the changes are limited to the minimum.

  12. TD-SCDMAShort Term Evolution —— MBMS TDD MBMS Technology • MBMS( Multimedia Broadcast and Multicast Services) is an unidirectional point to multipoint bearer service in which data is transmitted from a single source entity to multiple recipients. • MBMS is basically a new broadcast and multicast radio bearer technology; it can provide high speed downlink, non-voice services for multiple users simultaneously and regardless of user location and radio conditions in full area coverage.

  13. TD-SCDMAShort Term Evolution —— MBMS • Traditional non–MBMS results in radio resource bottlenecks by point-to-point transmission method • MBMS removes radio resource bottlenecks by point-to-multipoint transmission method • MBMS can efficiently utilize radio resource at air interface • MBMS can perform lower prices due to the saving in network resources

  14. TD-SCDMAShort Term Evolution —— MBMS TDD MBMS architecture • MBMS architecture comprises four blocks: User Equipment (UE), UTRAN (UMTS Terrestrial Radio Access Network, Core Network (including GGSN and SGSN) and new blocks- Broadcast Multicast - Service Centre (BM-SC) • MBMS architecture enables the efficient usage of radio-network and core-network resources, with an emphasis on radio interface efficiency

  15. TD-SCDMAShort Term Evolution —— MBMS TDD MBMS channels • MICH (MBMS notification Indicator Channel) • MCCH (MBMS point-to-multipoint Control Channel • MTCH (MBMS point-to-multipoint Traffic Channel) • MSCH (MBMS point-to-multipoint Scheduling Channel)

  16. TD-SCDMAShort Term Evolution —— MBMS MBMS Feature over TDD Technology -Simulcast Combining with timeslot reused • TD-SCDMA can use selective combing and soft coming, and it can also use simulcast combining through timeslot reused technology on its special frame structure • The complexity of UE will be increased due to combining of multiple radio links simultaneously in UE. But, in TD-SCDMA, it can be avoided by combining macro-diversity with timeslot reused • Timeslot reused can increase further throughput gains on the basis of selective combining and soft combining

  17. Higher Date rate in uplink Higher network efficiency Higher spectra efficiency Lower latency Efficient scheduling HSUPA TDD Faster retransmission Higher Modulation TD-SCDMAShort-term Evolution —— HSUPA FTP upload,Multimedia, Video- clips,email, telematics Gaming,video streaming Service requirement System requirement

  18. TD-SCDMAShort-term Evolution —— HSUPA TD-SCDMAHSUPAkey technology－Efficient Scheduling

  19. TD-SCDMAShort-term Evolution —— HSUPA TD-SCDMAHSUPA key technology－Efficient Scheduling • With Node B-based Packet Scheduling, two main improves: • Cell throughput is increased by means of faster adaption to interference variation and finer control of the total received uplink power. • User performance is improved by means of more frequently reallocation of radio resource to NRT users

  20. TD-SCDMAShort-term Evolution —— HSUPA TD-SCDMAHSUPA key technology－Faster retransmission 80ms

  21. TD-SCDMAShort-term Evolution —— HSUPA • Faster retransmission • Reaches maximum achievable cell throughput by means of faster retransmission of erroneously received data frame to reduce the number of RLC retransmission, since physical channel can be operated with higher BLER for same overall performance under this condition, which results to an increase in spectra efficiency. TD-SCDMAHSUPA key technology－Faster retransmission

  22. Q k Q k 8PSK I I k k 16QAM QPSK • Higher order modulation improve spectrum efficiency in good propagation condition. TD-SCDMAShort-term Evolution —— HSUPA TD-SCDMAHSUPA key technology－Higher order modulation

  23. TD-SCDMAShort-term Evolution —— HSUPA TD-SCDMA HSUPA’s latest progress • In March, 2006, at the TSG RAN meeting #31, a new work item proposal(“Proposed Work Item on 1.28 Mcps TDD Enhanced Uplink “) was approved. ZTE takes part in this WI with other companies. • The WI includes the following sub WIs: • 1.28 Mcps TDD Enhanced Uplink: Physical Layer • 1.28 Mcps TDD Enhanced Uplink: Layer 2 and 3 Protocol Aspects • 1.28 Mcps TDD Enhanced Uplink: UTRAN Iub/Iur Protocol Aspects • 1.28 Mcps TDD Enhanced Uplink: RF Radio Transmission/ Reception, System Performance Requirements and Conformance Testing

  26. 3GPPLong-term Evolution —— Target • Further enhanced MBMS • Reduced CAPEX and OPEX including backhaul • Cost effective migration from Rel-6 UTRA radio interface and architecture • Reasonable system and terminal complexity, cost, and power consumption. • Support of further enhanced IMS and core network • Backwards compatibility is highly desirable, but the trade off versus performance and/or capability enhancements should be carefully considered. • Efficient support of the various types of services, especially from the PS domain (e.g. Voice over IP, Presence) • System should be optimized for low mobile speed but also support high mobile speed • Operation in paired and unpaired spectrum should not be precluded • Possibility for simplified co-existence between operators in adjacent bands as well as cross-border co-existence
