5.7.1 Channel spacing

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 E-UTRA carriers is defined as following:

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

where BWChannel(1) and BWChannel(2) are the channel bandwidths of the two respective E-UTRA carriers. The channel spacing can be adjusted to optimize performance in a particular deployment scenario.

For 20MHz carriers in Band 46, the requirements apply for both 19.8 MHz and 20.1 MHz nominal carrier spacing.

5.7.1A CA Channel spacing

For intra-band contiguously aggregated carriers the channel spacing between adjacent component carriers shall be multiple of 300 kHz.

The nominal channel spacing between two adjacent aggregated E-UTRA carriers is defined as follows:

where BWChannel(1) and BWChannel(2) are the channel bandwidths of the two respective E-UTRA component carriers according to Table 5.6-1 with values in MHz. The channel spacing for intra-band contiguous carrier aggregation can be adjusted to any multiple of 300 kHz less than the nominal channel spacing to optimize performance in a particular deployment scenario.

For intra-band contiguous carrier aggregation with two or more component carriers in Band 46, the requirements apply for both 19.8 MHz and 20.1 MHz nominal carrier spacing between two 20 MHz component carriers, and for 15.0 MHz nominal carrier spacing between 10 MHz and 20 MHz component carriers.

5.7.2 Channel raster

The channel raster is 100 kHz for all bands, which means that the carrier centre frequency must be an integer multiple of 100 kHz.

5.7.3 Carrier frequency and EARFCN

The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range 0 – 262143. The relation between EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL_low and NOffs-DL are given in table 5.7.3-1 and NDL is the downlink EARFCN.

FDL = FDL_low + 0.1(NDL – NOffs-DL)

The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where FUL_low and NOffs-UL are given in table 5.7.3-1 and NUL is the uplink EARFCN.

FUL = FUL_low + 0.1(NUL – NOffs-UL)

The carrier frequency of NB-IoT in the downlink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range 0 – 262143 and the Offset of NB-IoT Channel Number to EARFCN in the range {-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,-0.5,0,1,2,3,4,5,6,7,8,9} for FDD and in the range {-10,-9,-8.5,-8,-7,-6,-5,-4.5,-4,-3,-2,-1,-0.5,0,1,2,3,3.5,4,5,6,7,7.5,8,9} for TDD. The relation between EARFCN, Offset of NB-IoT Channel Number to EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL is the downlink carrier frequency of NB-IoT, FDL_low and NOffs-DL are given in table 5.7.3-1, NDL is the downlink EARFCN, MDL is the Offset of NB-IoT Channel Number to downlink EARFCN.

FDL = FDL_low + 0.1(NDL – NOffs-DL) + 0.0025*(2MDL+1)

The carrier frequency of NB-IoT in the uplink is designated by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN) in the range 0 –262143, and the Offset of NB-IoT Channel Number to EARFCN in the range {-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9} for FDD and in the range {-11,-10,-9.5,-9,-8.5,-8,-7.5,-7,-6.5,-6,-5.5,-5, -4.5,-4,-3.5,-3,-2.5,-2,-1.5,-1,-0.5,0,0.5,1,1.5,2,2.5,3,3.5,4,4.5,5,5.5,6,6.5,7,7.5,8,8.5,9,9.5,10, 11} for TDD. The relation between EARFCN, Offset of NB-IoT Channel Number to EARFCN and the carrier frequency in MHz for the uplink is given by the following equation, where FUL is the uplink carrier frequency of NB-IoT, FUL_low and NOffs-UL are given in table 5.7.3-1, NUL is the uplink EARFCN, MUL is the Offset of NB-IoT Channel Number to uplink EARFCN.

FUL = FUL_low + 0.1(NUL – NOffs-UL) + 0.0025*(2MUL)

NOTE 1: For NB-IoT, NDL or NUL is different than the value of EARFCN that corresponds to E-UTRA downlink or uplink carrier frequency for in-band and guard band operation.

NOTE 2: For FDD MDL = -0.5 is not applicable for in-band and guard band operation. For TDD MDL {-0.5,+3.5,-4.5,+7.5,-8.5} is not applicable for in-band and guard band operation.

NOTE 3: For the carrier including NPSS/NSSS for in-band and guard band operation, MDL is selected from {-2,-1,0,1}.

NOTE 4: For the carrier including NPSS/NSSS for stand-alone operation, MDL = -0.5.

5.7.4 EARFCN sets for Type B multi-carrier downlink transmissions and conversion to Type 2 channel access for multi-carrier uplink transmissions on multiple Scells configured in Band 46

If the maximum frequency separation between the center frequencies of any two of the carriers on which LAA transmissions are performed is > 62 MHz, then on a configured set of carriers with carrier frequencies that are a subset of any of the following sets of EARFCN, downlink transmissions in accordance with Type B multi-carrier access procedure as defined in 4.1.6.2 of TS 37.213 [20] are allowed:

– for sets of two Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290}, {47490, 47690}, {47890, 48090}, {48290, 48490}, {50290, 50490}, {50690, 50890}, {51090, 51290}, {51490, 51690}, {51890, 52090}, {52290, 52490}; {52740, 52940}; {53140, 53340}

– for sets of four Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290, 47490, 47690}, {47890, 48090, 48290, 48490}, {50290, 50490, 50690, 50890}, {51090, 51290, 51490, 51690}, {51890, 52090, 52290, 52490}, {52740, 52940, 53140, 53340}

– for sets of eight Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290, 47490, 47690, 47890, 48090, 48290, 48490}, {50290, 50490, 50690, 50890, 51090, 51290, 51490, 51690}

Additionally, if the maximum frequency separation between the center frequencies of any two of the carriers on which LAA transmissions are performed is ≤ 62 MHz, then the Type B multi-carrier access procedure as defined in 4.1.6.2 of TS 37.213 [20] is allowed without any of the above EARFCN restrictions.

If the maximum frequency separation between the center frequencies of any two of the carriers on which LAA transmissions are performed is > 62 MHz and transmissions are permitted by national regulations, then Type B multi-carrier access procedure is also allowed only within a configured set of carriers that does not include any carrier frequencies that are included in any of the sets of EARFCN above, as defined in Note 3 in Table 5.7.3-1. EARFCN values that are not included in any of the sets of EARFCN above are as follows: n-2, n-1, n, n+1, n+2 | n = {46890, 48690, 50090, 53540}

For any LAA transmissions, single carrier access procedure as defined in clause 4.1.1 and 4.1.2 of TS 37.213 [20] or Type A multi-carrier access procedure as defined in clause 4.1.6.1 of TS 37.213 [20] are also allowed.

On a configured set of carriers with carrier frequencies that are a subset of any of the following sets of EARFCN, if the eNB schedules a UE to transmit in a subframe on the configured set of carriers, and if the UL grants scheduling PUSCH transmissions on any of the said set of carriers indicate Type 1 channel access procedure, and if the same ‘PUSCH starting position‘ is indicated for all carriers, transmissions in accordance with the conditions for Type 2 channel access specified in clause 15.2.1 of [11] are allowed:

– for sets of two Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290}, {47490, 47690}, {47890, 48090}, {48290, 48490}, {50290, 50490}, {50690, 50890}, {51090, 51290}, {51490, 51690}, {51890, 52090}, {52290, 52490}; {52740, 52940}; {53140, 53340}

– for sets of four Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290, 47490, 47690}, {47890, 48090, 48290, 48490}, {50290, 50490, 50690, 50890}, {51090, 51290, 51490, 51690}, {51890, 52090, 52290, 52490}, {52740, 52940, 53140, 53340}

– for sets of eight Scells: n-2, n-1, n, n+1, n+2 | n = {47090, 47290, 47490, 47690, 47890, 48090, 48290, 48490}, {50290, 50490, 50690, 50890, 51090, 51290, 51490, 51690}

Type 2 channel access is also allowed within a configured set of carriers that does not include any carrier frequencies that are included in any of the sets of EARFCN above, as defined in Note 3 in Table 5.7.3-1. EARFCN values that are not included in any of the sets of EARFCN above are as follows: n-2, n-1, n, n+1, n+2 | n = {46890, 48690, 50090, 53540}
