6.6.2F.1 Spectrum emission mask
The spectrum emission mask of the category NB1 and NB2 UE applies to frequencies (ΔfOOB) starting from the ± edge of the assigned category NB1 or NB2 channel bandwidth. For frequencies greater than (ΔfOOB) as specified in Table 6.6.2F.1-1 the spurious requirements in subclause 6.6.3 are applicable.
The power of any category NB1 or NB2 UE emission shall not exceed the levels specified in Table 6.6.2F.1-1. The spectrum emission limit between each ΔfOOB is linearly interpolated.

In addition to the spectrum emission mask requirement in Table 6.6.2F.1-1 a category NB1 or NB2 UE shall also meet the applicable E-UTRA spectrum emission mask requirement in sub-clause 6.6.2. E-UTRA spectrum emission requirement applies for frequencies that are Foffset away from edge of NB1 or NB2 channel edge as defined in Table 6.6.2F.1-2.

Note: Foffset in Table 6.6.2F.1-2 is used to guarantee co-existence for guard-band operation.
6.6.2F.2 Additional Spectrum Emission Mask for Category NB1 and NB2
This requirement is specified in terms of an "additional spectrum emission" requirement.
6.6.2F.2.1 Minimum requirement (network signalled value "NS_02")
Additional spectrum emission requirements are signalled by the network to indicate that the UE shall meet an additional requirement for a specific deployment scenario as part of the cell broadcast message.
When "NS_02" is indicated in the cell, the NB-IoT channel is deployed in the lower guard-band of a 10MHz E-UTRA channel and the separation between the two channel centres is equal to 4.695 MHz. The power of any UE emission shall not exceed the levels specified in Table 6.6.2.1.1-1 for the specified E-UTRA channel bandwidth and the levels specified in Table 6.6.2F.1-1 for the NB-IoT channel.
Note: UEs that meet the above emission requirement would automatically meet the E-UTRA additional spectrum emission masks as defined in 6.6.2.2 for the applicable operating bands.
6.6.2F.2.2 Minimum requirement (network signalled value "NS_03")
Additional spectrum emission requirements are signalled by the network to indicate that the UE shall meet an additional requirement for a specific deployment scenario as part of the cell broadcast message.
When "NS_03" is indicated in the cell, the NB-IoT channel is deployed in the upper guard-band of a 10MHz E-UTRA channel and the separation between the two channel centres is equal to 4.695 MHz. The power of any UE emission shall not exceed the levels specified in Table 6.6.2.1.1-1 for the specified E-UTRA channel bandwidth and the levels specified in Table 6.6.2F.1-1 for the NB-IoT channel.
Note: UEs that meet the above emission requirement would automatically meet the E-UTRA additional spectrum emission masks as defined in 6.6.2.2 for the applicable operating bands.
6.6.2F.3 Adjacent Channel Leakage Ratio for category NB1 and NB2
Adjacent Channel Leakage power Ratio is the ratio of the filtered mean power centred on the assigned channel frequency to the filtered mean power centred on an adjacent channel frequency. The assigned category NB1or NB2 channel power and adjacent channel power are measured with filters and measurement bandwidths specified in Table 6.6.2F.3-1. If the measured adjacent channel power is greater than –50dBm then the category NB1 or NB2 UE ACLR shall be higher than the value specified in Table 6.6.2F.3-1. GSMACLR requirement is intended for protection of GSM system. UTRAACLR requirement is intended for protection of UTRA and E-UTRA systems.
