BS Channel Bandwidth (MHz) Total Power Dynamic Range (dB) SCS 15 kHz SCS 30 kHz SCS 60 kHz a square filter of bandwidth equal to the transmission bandwidth configuration of the BS (BW config) centered around the assigned channel frequency during the transmitter OFF period. The parameter N = SCS/15, where SCS is the subcarrier spacing in kHz. For multi- band connectors and for single-band connectors supporting transmission in multiple operat- ing bands, the requirement is only applicable during the transmitter OFF period in all supported operating bands. For BSs supporting intraband contiguous carrier aggregation, the transmitter OFF power is defined as the mean power measured over 70/N (us) filtered with a square filter of bandwidth equal to the aggregated BS channel bandwidth BWchannel_CA centered around (fedge-high fedge-low) /2 during the transmitter OFF period. In this case, parameter N = SCS/15, where SCS is the smallest supported subcarrier spacing in kHz in the aggregated BS channel bandwidth [5]. The requirements for transmitted signal quality specify the extent to which the transmitted signal from the BS or the device deviates from a reference signal. The transmitted signal impairments are caused by the transmitter RF components and particularly the nonlinear response of the power amplifier (PA). The signal quality of the BS or the device can be 680 Chapter 5 Table 5.9: Error vector magnitude requirements for base station type 1-C and BS type 1-H [5].
