9.7.2.1 General

The OTA occupied bandwidth is the width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers emitted are each equal to a specified percentage /2 of the total mean transmitted power. See also recommendation ITU-R SM.328 [17].

The value of /2 shall be taken as 0.5%.

The OTA occupied bandwidth requirement applies during the transmitter ON period for a single transmitted carrier. The minimum requirement below may be applied regionally. There may also be regional requirements to declare the OTA occupied bandwidth according to the definition in the present clause.

The OTA occupied bandwidth is defined as a single direction requirement and shall be met in the manufacturer’s declared OTA coverage range at the RIB.

9.7.2.2 Minimum requirement for MSR operation

For AAS BS in MSR operation, the minimum requirement for OTA occupied bandwidth is the same as that stated in 3GPP TS 37.104 [9], subclause 6.6.3.

9.7.2.3 Minimum requirement for single RAT UTRA operation

For AAS BS in single RAT UTRA operation FDD, the minimum requirement for OTA occupied bandwidth is the same as that stated in 3GPP TS 25.104 [6] subclause 6.6.1.

9.7.2.4 Minimum requirement for single RAT E-UTRA operation

For AAS BS in single RAT E-UTRA operation, the minimum requirement for OTA occupied bandwidth is the same as that stated in 3GPP TS 36.104 [8], subclause 6.6.1.
