1 For a base station supporting non-contiguous spectrum operation within any operating band, the emission limits within sub-block
gaps is calculated as a cumulative sum of contributions from adjacent sub-blocks on each side of the sub-block gap, where the
contribution from the far-end sub-block is scaled according to the measurement bandwidth of the near-end sub-block. Exception is
Δf ≥ 10 MHz from both adjacent sub-blocks on each side of the sub-block gap, where the emission limits within sub-block gaps is –
16 dBm/100 kHz.
2 f_offset is the separation between the channel edge frequency and the center of the measuring filter.
3 For a multi-band connector with Inter RF Bandwidth gap < 2*Δf
calculated as a cumulative sum of contributions from adjacent sub-blocks or RF Bandwidth on each side of the Inter RF Bandwidth
gap, where the contribution from the far-end sub-block or RF Bandwidth is scaled according to the measurement bandwidth of the
near-end sub-block or RF Bandwidth.
