6.6.3 Occupied bandwidth

37.1043GPPMulti-Standard Radio (MSR) Base Station (BS) radio transmission and receptionNR, E-UTRA, UTRA and GSM/EDGERelease 17TS

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 ITU-R Recommendation SM.328 [11].

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

The requirement in the present clause applies during the transmitter ON period for a single transmitted carrier. For E-UTRA intra-band contiguous carrier aggregation, the requirement in clause 6.6.1 of TS 36.104 [4] applies for the E-UTRA component carriers that are aggregated. For NR intra-band contiguous carrier aggregation, the requirement in clause 6.6.2.2 of TS 38.104 [17] applies for the NR component carriers that are aggregated. 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.

6.6.3.1 Minimum requirement

The occupied bandwidth shall be less than values listed in Table 6.6.3.1-1.
