Some requirements in the present document may only apply in certain regions either as optional requirements, or set by local and regional regulation as mandatory requirements. It is normally not stated in the 3GPP specifications under what exact circumstances that the requirements apply, since this is defined by local or regional regulation.

Table 4.4-1 lists all requirements in the present specification that may be applied differently in different regions.

Table 4.4-1: List of regional requirements

Clause	Requirement	Comments
5.2	Operating bands	Some NR operating bands may be applied regionally.
6.2.3	IAB output power: Additional requirements	These requirements may be applied regionally as additional IAB output power requirements.
9.7.2	OTA occupied bandwidth	The requirement may be applied regionally. There may also be regional requirements to declare the occupied bandwidth according to the definition in present specification.
9.7.4.2 9.7.4.3	OTA operating band unwanted emissions	Category A or Category B operating band unwanted emissions limits may be applied regionally.
9.7.4.4.1	OTA operating band unwanted emissions: Limits in FCC Title 47 [14]	The IAB may have to comply with the additional requirements, when deployed in regions where those limits are applied, and under the conditions declared by the manufacturer.
9.7.5.2.2 9.7.5.3.2	OTA Tx spurious emissions	Category A or Category B spurious emission limits, as defined in Recommendation ITU-R SM.329 [2], may apply regionally. The emission limits for IAB type 1-O specified as the basic limit + X (dB) are applicable, unless stated differently in regional regulation.
9.7.5.2.3 9.7.5.3.3	OTA Tx spurious emissions: additional requirements	These requirements may be applied for the protection of system operating in frequency ranges other than the IAB operating band.
9.8.2	OTA transmitter intermodulation	Interfering signal positions that are partially or completely outside of any downlink operating band of the IAB are not excluded from the requirement in Japan in Band n77, n78, n79.
10.7.2 10.7.3	OTA Rx spurious emissions	The emission limits for IAB type 1-O specified as the basic limit + X (dB) are applicable, unless stated differently in regional regulation.
