Huawei Technologies 1 Technology changes. Communication lasts. AIE Requirements and Competitions

Huawei Technologies 2 Requirements from the Future Mobile Communication Market

Huawei Technologies 3  From the Customer Perspective Rich Services every where (Mobile and Multimedia) Guaranteed Quality of Services (QoS) Cheap to use Convenience to use Low power consumption Many Kinds of terminals suitable for different scenarios and different users (from high end to low end)

Huawei Technologies 4  From the Operator’s Perspective Rich Services and Services Convergency Guaranteed Quality of Services (QoS) Low cost to deploy and operate Attract all kinds of users

Huawei Technologies 5  Technical Requirements Corresponding to Market Requirements Improve coverage for current access schemes and features Control of Quos to support different kinds of Services Low latency (Short transmission delay and call establishment time) High data speed, Capacity Smooth migration with reasonable CAPEX and OPEX Support simple design of terminals

Huawei Technologies 6 Competition from other Technologies

Huawei Technologies 7  IEEE and Standard Progress  IEEE has published Standard which provides four kinds of air interface,  IEEE P802.16e, "Physical and Medium Access Control Layers for Combined Fixed and Mobile Operation in Licensed Bands" will be published at the first season in 2005, which select OFDM and OFDMA as its air interface.  IEEE P802.16g, "Management Plane Procedures and Services” is started now and will be published at early 2007.

Huawei Technologies 8 Features  Support for licensed and license-exempt frequency bands, channel widths ranging from 1.25 to 20 MHz,  Quality of Service (QoS) establishment on a per-connection basis,  multicast support,  low latency/low packet loss handovers.

Huawei Technologies 9 IEEE evolution

Huawei Technologies 10  3GPP LTE (Long Term Evolution) Standard Progress  In 2001, 3GPP held the “Future Evolutions Workshop”  3GPP has made some research in OFDM, and completed the document as TR v1.2, “Feasibility Study for OFDM for UTRAN enhancement”  DoCoMo presented the concept of Super 3G  Nov., GPP held the “RAN Long Term Evolution Work Shop” and set up the LTE Study Item

Huawei Technologies 11 LTE Requirement  Reduced cost per bit Improve spectrum efficiency ( e.g. 2-4 x Rel6) Reduce cost of backhaul (transmission in UTRAN)  Increased service provisioning – more services at lower cost with better user experience Focus on delivery of services utilising ”IP” Reduce setup time and round trip time Increase the support of QoS for the various types of services (e.g. Voice over IP) Increase “cell edge bitrate” whilst maintaining same site locations as deployed today

Huawei Technologies 12  Architecture and mobility Need to consider UTRAN Evolution and UTRA Evolution at the same time aiming at simplifying the current architecture Shall provide open interfaces to support Multi- vendor deployments Consider robustness – no single point of failure Support multi-RAT with resources controlled from the network Support of seamless mobility to legacy systems as well as to other emerging systems including inter RAT Handovers and Service based RAT Selection Maintain appropriate level of security

Huawei Technologies 13  Allow for reasonable terminal power consumption

Huawei Technologies 14 Suggestion

Huawei Technologies 15  To Create the Study Item of AIE  Match the Performance of 3GPP LTE  Time to Market Before 2009, and Complete the Standard Before 2007  Harmonization HRPD and 1X EV-DV or Enhance interoperation ability  Pay more attentions to new technologies such as OFDM and MIMO

Huawei Technologies 16 Thank you for your attention!
