6.6.2.1 General

The 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 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 occupied bandwidth according to the definition in the present clause.

6.6.2.2 Minimum requirement for MSR operation

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

6.6.2.3 Minimum requirement for single RAT UTRA operation

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

For single RAT UTRA TDD, 1,28Mcps option AAS BS, the minimum requirement for occupied bandwidth is the same as that stated in 3GPP TS 25.105 [7], subclause 6.6.1.

6.6.2.4 Minimum requirement for single RAT E-UTRA operation

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