25.1163GPPRelease 17TSUTRA repeater radio transmission and reception (LCR TDD)

9.1 Spectrum emission mask

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.

For regions where this clause applies, the requirement shall be met by a 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 table 9.1 to 9.3 for the appropriate LCR TDD repeater maximum output power, in the frequency range from f = 0.8 MHz to f _max from the carrier frequency, where:

– f is the separation between the carrier frequency and the nominal -3dB point of the measuring filter closest to the carrier frequency.

– f_offset is the separation between the carrier frequency and the center frequency of the measuring filter.

– f_offset_max is either 4 MHz or the offset to the UMTS Tx band edge as defined in section 5.2, whichever is the greater.

– f _max is equal to f_offset_max minus half of the bandwidth of the measurement filter.

9.2 Spurious emissions

Spurious emissions are emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission, intermodulation products and frequency conversion products, but exclude out of band emissions. This is measured at the base station RF output port.

The requirements shall apply whatever the type of transmitter considered (single carrier or multi carrier). It applies for all transmission modes foreseen by the manufacturer’s.

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.
