TD-SCDMA Short-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

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

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-SCCH and 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.

TD-SCDMA Short 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

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

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

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

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

TD-SCDMA HSUPA key technology － Efficient Scheduling


19

TD-SCDMA HSUPA 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-SCDMA HSUPA key technology － Faster retransmission

80ms


21

TD-SCDMA HSUPA key technology － Faster retransmission

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.


22

TD-SCDMA HSUPA key technology － Higher order modulation

• Higher order modulation improve spectrum efficiency in good propagation condition.

3GPP Long-term Evolution —— Target

Significantly increased peak data rate e.g. 100 Mbps (downlink) and 50 Mbps (uplink)

Increase “cell edge bitrate” whilst maintaining same site locations as deployed today

Significantly improved spectrum efficiency ( e.g. 2-4 x Rel6) Possibility for a Radio-access network latency (user-plane UE – RNC (or

corresponding node above Node B) - UE) below 10 ms Significantly reduced C-plane latency (e.g. including the possibility to

exchange user-plane data starting from camped-state with a transition time of less than 100 ms (excluding downlink paging delay))

Scaleable bandwidth 5, 10, 20 and possibly 15 MHz [1.25,] 2.5 MHz: to allow flexibility in narrow spectral allocations where

the system may be deployed Support for inter-working with existing 3G systems and non-3GPP specified

systems

26

3GPP Long-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
