5.4B.0 General

The channel arrangement for intra-band EN-DC operations in FR1 is specified in TS 36.101 [4] and TS 38.101-1 [2] , respectively.

5.4B.1 Channel spacing for intra-band EN-DC carriers

The spacing between carriers will depend on the deployment scenario, the size of the frequency block available and the channel bandwidths. The nominal channel spacing between E-UTRA carrier and an adjacent NR carrier for intra-band contiguous EN-DC is defined as following:

– For NR operating bands with 100 kHz channel raster,

Nominal Channel spacing = (BW_{E-UTRA_Channel} + BW_{NR_Channel})/2

– For NR operating bands with 15 kHz channel raster,

– Nominal Channel spacing = (BW_{E-UTRA_Channel} + BW_{NR_Channel})/2+{-5kHz, 0kHz, 5kHz} for ∆F_Raster equals to 15 kHz

– Nominal Channel spacing = (BW_{E-UTRA_Channel} + BW_{NR_Channel})/2+{-10 kHz, 0 kHz, 10 kHz} for ∆F_Raster equals to 30 kHz

where BW_{E-UTRA_Channel} and BW_{NR_Channel} are the channel bandwidths of the E-UTRA and NR carriers, ∆F_Raster is the band dependent channel raster granularity defined in TS38.101-1[2]. The channel spacing can be adjusted depending on the channel raster to optimize performance in a particular deployment scenario.

For intra-band non-contiguous EN-DC the channel spacing between E-UTRA and NR carriers shall be larger than the nominal channel spacing defined in this clause.
