1  ScopeWord‑p. 5

This document is a technical report of the UMTS1500 work items. The purpose of these work items is to provide UMTS specification support for UTRA FDD in the 1500 MHz in Japan. In addition to the schedule and status of the work items, the report includes a description of the motivation, requirements, study results and specification recommendations.
This document is a 'living' document, periodically updated and presented at all TSG-RAN meetings until all related CRs are agreed and approved.

4  Introduction

A working group has been established under the Information and Communications Council of Japan to consider the technical condition of the frequency re-arrangement in 1500 MHz band in order to enhance frequency efficiency. Therefore, the proponents of this work item believe that there is high possibility that IMT-2000 would be introduced in Japan in the band near future.
It is suggested that the consideration of the evolution and migration to introduce DS-CDMA in the 1500 MHz band being studied in the working group under the Information and Communications Council of Japan could be used as the basis for this work, which would reduce the effort required within 3GPP.

4.1  Task Description

The purpose of this work item is to study of UMTS1500 for a potential deployment in Japan. The study includes co-existing studies with the following technologies: PDC system (ARIB standard RCR STD-27), DIGITAL MCA system (ARIB standard RCR STD-32), Radio astronomy systems, and Mobile satellite communication service, taking the frequency reframing plan in Japan into account.
The Work Item description for UMTS1500 was approved at RAN#35 [1].

4.2  Rationale for UMTS1500

This WI enables the introduction of W-CDMA radio interface to the 1427.9 - 1452.9 MHz (UL) and 1475.9 - 1500.9 MHz (DL) band.
