IMT cellular networks; Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive; Part 7: CDMA TDD (UTRA TDD) Base Stations (BS)
|Publication Date:||1 July 2011|
The present document applies to the following radio equipment type:
• Base stations for IMT-2000 CDMA TDD (UTRA TDD).
The requirements in the present document apply to both Wide Area Base Stations and Local Area Base Stations unless otherwise stated.
The UTRA TDD component of IMT-2000 CDMA TDD supports three options of the TDD mode with the chip rates of 3,84 Mchip/s, 1,28 Mchip/s and 7,68 Mchip/s. These three options are called the 3,84 Mcps TDD option, the 1,28 Mchip/s TDD option and the 7,68 Mcps TDD option respectively. The requirements are listed in different clauses only if the parameters deviate.
The present document covers requirements for:
• 3,84 Mcps TDD option Base Station for Releases 99, 4, 5, 6, 7, 8 and 9;
• 1,28 Mcps TDD option Base Stations for Releases 4, 5, 6, 7, 8 and 9;
• 7,68 Mcps TDD option Base Stations for Releases 7, 8 and 9.
For the case of IMB, only the 3,84 Mcps UTRA TDD option applies.
For general purpose Base Stations of Releases 99 and 4 only the requirements for Wide Area Base Stations apply.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (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 essential requirements under other parts of article 3 of the R&TTE Directive [i.2] may apply to equipment within the scope of the present document.
