9.1 Spectrum emission mask

9.1.1 Definition and applicability

The spectrum emission mask specifies the limit of the transmitter out of band emissions at frequency offsets from the assigned channel frequency of the wanted signal between 0,8 MHz and 4 MHz.

The mask defined in Table 9.1 to 9.3 may be mandatory in certain regions. In other regions this mask may not be applied.

9.1.2 Minimum Requirements

For regions where this subclause applies, the requirement shall be met by LCR TDD repeater transmitting on a single RF carrier configured in accordance with the manufacturer’s specification. Emissions shall not exceed the maximum level specified in tables 9.1 to 9.3 in the frequency range of f_offset from 0.815 MHz to f_offsetmax from the carrier frequency, where:

– f_offset is the separation between the carrier frequency and the centre of the measurement filter

– f_offsetmax is either 4 MHz or the offset to the UMTS Tx band edge as defined in subclause 4.2, whichever is the greater.

For 1.28 Mcps TDD option, either requirement applies at frequencies within the specified frequency ranges which are more than 4 MHz under the first carrier frequency used or more than 4 MHz above the last carrier frequency used.

Unless otherwise stated, all requirements are measured as mean power.
