1 Scope
The present document applies to the following radio equipment type:
• User equipment 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: IMT-2000 CDMA TDD service frequency bands
Operating band Direction of transmission IMT-2000 CDMA TDD service frequency bands
a Transmit and Receive 1 900 MHz to 1 920 MHz
Transmit and Receive 2 010 MHz to 2 025 MHz
d Transmit and Receive 2 570 MHz to 2 620 MHz
IMT-2000 CDMA TDD (UTRA TDD) supports two options of the TDD mode with the chip rates of 3,84 Mcps and
1,28 Mcps. These two options are called the 3,84 Mcps TDD option and the 1,28 Mcps 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 user equipment for Release 99, 4, 5, 6 and 7 and for 1,28 Mcps TDD option
user equipment for Release 4, 5, 6 and 7.
The present document covers 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 essential requirements
under other parts of article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site: http://www.newapproach.org/.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the user
equipment, which shall be declared by the supplier. The equipment shall comply with all the technical requirements of
the present document at all times when operating within the boundary limits of the declared operational environmental
profile.
For guidance on how a supplier can declare the environmental profile see annex B.
4.2 Conformance requirements
The requirements in the present document are based on the assumption that the operating band, band (a) and (d), are
shared between systems of the IMT-2000 family or systems having compatible characteristics.
4.2.1 Introduction
To meet the essential requirement under article 3.2 of the R&TTE Directive [1] for IMT-2000 User Equipment eight
essential parameters in addition to those in EN 301 908-1 [14] have been identified. Table 2 provides a cross reference
between these eight essential parameters and the corresponding eleven technical requirements within the scope of the
present document.
To fulfil an essential parameter the compliance with all the corresponding technical requirements in table 2 must be
verified.

The technical requirements apply for declared operating bands.
4.2.2 Spectrum emission mask
4.2.2.1 Definition
The spectrum emission mask establishes out-of-band emission power limits of the user equipment transmitter.
Out-of-band emissions are defined as unwanted emissions outside the channel bandwidth resulting from the modulation
process and non-linearity in the transmitter but excluding spurious emissions.
4.2.2.1.1 3,84 Mcps TDD option
The spectrum emission mask of the UE applies to frequency offsets between 2,5 MHz and 12,5 MHz on both sides of
the UE centre carrier frequency. The out-of-channel emission is specified as a power level relative to the RRC-filtered
mean power of the UE carrier.

12 ETSI EN 301 908-6 V3.2.1 (2007-09)
4.2.2.1.2 1,28 Mcps TDD option
The spectrum emission mask of the UE applies to frequency offsets between 0,8 MHz and 4 MHz on both sides of the
UE centre carrier frequency. The out-of-channel emission is specified as a power level relative to the RRC-filtered
mean power of the UE carrier.
4.2.2.2 Limits
4.2.2.2.1 3,84 Mcps TDD option
The power of any UE emission shall not exceed the levels specified in table 3.

NOTE 1: Δf is the separation between the carrier frequency and the centre of the measuring filter.
NOTE 2: The first measurement position with a 30 kHz filter is at Δf equals to 2,515 MHz; the last is at Δf
equals to 3,485 MHz.
NOTE 3: The first measurement position with a 1 MHz filter is at Δf equals to 4 MHz; the last is at Δf
equals to 12 MHz. As a general rule, the resolution bandwidth of the measuring equipment
should be equal to the measurement bandwidth. To improve measurement accuracy, sensitivity
and efficiency, the resolution bandwidth can be d
