scope:

The present document applies to the following radio equipment type: Base stations for IMT-2000 CDMA TDD (UTRA TDD). This radio equipment type is capable of operating in all or any part of the frequency bands given in table 1. Table 1: CDMA TDD base station frequency bands Direction of transmission CDMA TDD base station frequency bands Transmit and Receive 1 900 MHz to 1 920 MHz Transmit and Receive 2 010 MHz to 2 025 MHz The requirements in the present document apply to both Wide Area base stations and Local Area base stations unless otherwise stated. IMT-2000 CDMA TDD (UTRA TDD) supports two options of the TDD mode with the chip rates of 3,84 Mchip/s and 1,28 Mchip/s. These two options are called the 3,84 Mcps TDD option and the 1,28 Mchip/s TDD option respectively. The requirements are listed in different subsections only if the parameters deviate. The present document covers requirements for 3,84 Mcps TDD option base station for Release 99, 4 and 5 and for 1,28 Mcps TDD option base stations for Release 4 and 5. For general purpose base stations of Release 99 and 4 only the requirements for Wide Area base stations shall apply. The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) article 3.2, which states that "[ ] radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essentia
