5.4.1 Channel spacing

5.4.1.1 Channel spacing for adjacent NR 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 two adjacent NR carriers is defined as following:

– For NR operating bands with 100 kHz channel raster,

Nominal Channel spacing = (BW_Channel(1) + BW_Channel(2))/2

– For NR operating bands with 15 kHz channel raster,

Nominal Channel spacing = (BW_Channel(1) + BW_Channel(2))/2+{-5 kHz, 0 kHz, 5 kHz} for ∆F_Raster equals 15 kHz

Nominal Channel spacing = (BW_Channel(1) + BW_Channel(2))/2+{-10 kHz, 0 kHz, 10 kHz} for ∆F_Raster equals 30 kHz

where BW_Channel(1) and BW_Channel(2) are the channel bandwidths of the two respective NR carriers. The channel spacing can be adjusted depending on the channel raster to optimize performance in a particular deployment scenario.

5.4.2 Channel raster

5.4.2.1 NR-ARFCN and channel raster

The global frequency channel raster defines a set of RF reference frequencies F_REF. The RF reference frequency is used in signalling to identify the position of RF channels, SS blocks and other elements.

The global frequency raster is defined for all frequencies from 0 to 100 GHz. The granularity of the global frequency raster is ΔF_Global.

RF reference frequencies are designated by an NR Absolute Radio Frequency Channel Number (NR-ARFCN) in the range (0…2016666) on the global frequency raster. The relation between the NR-ARFCN and the RF reference frequency F_REF in MHz is given by the following equation, where F_REF-Offs and N_Ref-Offs are given in table 5.4.2.1-1 and N_REF is the NR-ARFCN.

F_REF = F_REF-Offs + ΔF_Global (N_REF – N_REF-Offs)

Table 5.4.2.1-1: NR-ARFCN parameters for the global frequency raster

Frequency range (MHz)	ΔF_Global(kHz)	F_REF-Offs (MHz)	N_REF-Offs	Range of N_REF
0 – 3000	5	0	0	0 – 599999
3000 – 24250	15	3000	600000	600000 – 2016666

The channel raster defines a subset of RF reference frequencies that can be used to identify the RF channel position in the uplink and downlink. The RF reference frequency for an RF channel maps to a resource element on the carrier. For each operating band, a subset of frequencies from the global frequency raster are applicable for that band and forms a channel raster with a granularity ΔF_Raster, which may be equal to or larger than ΔF_Global.

For SUL bands except n95, n97, n98 and for the uplink of all FDD bands defined in Table 5.2-1, and for TDD bands n34, n39, n48, n90, n38 and n40

F_{REF, shift} = F_REF+ Δ_shift, Δ_shift= 0 kHz or 7.5 kHz.

where Δ_shift is signalled by the network in higher layer parameter frequencyShift7p5khz [7]. For Band n34, n38, n39, n40, n48 F_{REF, shift} is only applicable to uplink transmissions using a 15 kHz SCS.

The mapping between the channel raster and corresponding resource element is given in Clause 5.4.2.2. The applicable entries for each operating band are defined in Clause 5.4.2.3.

5.4.2.2 Channel raster to resource element mapping

The mapping between the RF reference frequency on the channel raster and the corresponding resource element is given in Table 5.4.2.2-1 and can be used to identify the RF channel position. The mapping depends on the total number of RBs that are allocated in the channel and applies to both UL and DL. The mapping must apply to at least one numerology supported by the UE.

	N_RBmod2 = 0	N_RBmod2 = 1

Physical resource block number

, n_PRB, N_RB are as defined in TS 38.211[6].

5.4.2.3 Channel raster entries for each operating band

The RF channel positions on the channel raster in each NR operating band are given through the applicable NR-ARFCN in Table 5.4.2.3‑1, using the channel raster to resource element mapping in clause 5.4.2.2.

For NR operating bands with 100 kHz channel raster, ΔF_Raster = 20 × ΔF_Global. In this case every 20^th NR-ARFCN within the operating band are applicable for the channel raster within the operating band and the step size for the channel raster in Table 5.4.2.3‑1 is given as <20>.

For NR operating bands with 15 kHz channel raster below 3GHz, ΔF_Raster = I × ΔF_Global, where I ϵ {3,6}. Every I^th NR‑ARFCN within the operating band are applicable for the channel raster within the operating band and the step size for the channel raster in Table 5.4.2.3‑1 is given as < I >.

For NR operating bands with 15 kHz channel raster above 3GHz, ΔF_Raster = I × ΔF_Global, where I ϵ {1,2}. Every I^th NR‑ARFCN within the operating band are applicable for the channel raster within the operating band and the step size for the channel raster in table 5.4.2.3-1 is given as <I>.

In frequency bands with two or more ΔF_Raster, the higher ΔF_Raster: For 15 kHz and 30 kHz channel raster applies to channels using only the SCS that is equal to or larger than the higher ΔF_Raster and SSB SCS is equal to the higher ∆F_Raster.

5.4.3 Synchronization raster

5.4.3.1 Synchronization raster and numbering

The synchronization raster indicates the frequency positions of the synchronization block that can be used by the UE for system acquisition when explicit signalling of the synchronization block position is not present.

A global synchronization raster is defined for all frequencies. The frequency position of the SS block is defined as SS_REF with corresponding number GSCN. The parameters defining the SS_REF and GSCN for all the frequency ranges are in Table 5.4.3.1-1.

The resource element corresponding to the SS block reference frequency SS_REF is given in clause 5.4.3.2. The synchronization raster and the subcarrier spacing of the synchronization block is defined separately for each band.

Table 5.4.3.1-1: GSCN parameters for the global frequency raster

Frequency range	SS Block frequency position SS_REF	GSCN	Range of GSCN
0 – 3000 MHz	N * 1200kHz + M * 50 kHz, N=1:2499, M ϵ {1,3,5} (Note 1)	3N + (M-3)/2	2 – 7498
3000 – 24250 MHz	3000 MHz + N * 1.44 MHz N = 0:14756	7499 + N	7499 – 22255
NOTE 1: The default value for operating bands with which only support SCS spaced channel raster(s) is M=3.

5.4.3.2 Synchronization raster to synchronization block resource element mapping

The mapping between the synchronization raster and the corresponding resource element of the SS block is given in Table 5.4.3.2-1.

Table 5.4.3.2-1: Synchronization raster to SS block resource element mapping

Resource element index

120

is the subcarrier number of SS/PBCH block defined in TS 38.211 clause 7.4.3.1 [6].

5.4.3.3 Synchronization raster entries for each operating band

The synchronization raster for each band is give in Table 5.4.3.3-1. The distance between applicable GSCN entries is given by the <Step size> indicated in Table 5.4.3.3-1.

NOTE 1: Void NOTE 2: The range of TX-RX frequency separation given paired UL and DL channel bandwidths BW_UL and BW_DL is given by the respective lower and upper limit F_{DL_low} – F_{UL_high} + 0.5(BW_DL + BW_UL) and F_{DL_high} – F_{UL_low} – 0.5(BW_DL + BW_UL). The UL and DL channel bandwidth combinations specified in Table 5.3.5-1 and 5.3.6-1 depend on the subcarrier spacing configuration μ [6].
