    CEPT/ERC/RECOMMENDATION 12-08 E (Podebrady 1997, Saariselkä 1998)

    HARMONISED RADIO FREQUENCY CHANNEL ARRANGEMENTS AND BLOCK

    ALLOCATIONS FOR LOW, MEDIUM AND HIGH CAPACITY SYSTEMS

    IN THE BAND 3600 MHz TO 4200 MHz

    Recommendation adopted by the Working Group “Spectrum Engineering” (WGSE):

“The European Conference of Postal and Telecommunications Administrations

considering

    1) that CEPT has a long term objective to harmonise the use of frequencies throughout Europe;

    2) that CEPT should develop radio frequency channel arrangements and block allocation rules in order to

    make the most effective use of the spectrum for point to point (P-P) and point to multipoint (P-MP)

    applications;

    3) that the achievement of harmonisation requires the adoption of a minimum number of channel

    arrangements and block allocation rules;

noting

    a) that Article S.5 of the Radio Regulations allocates the band 3600 MHz to 4200 MHz on a primary basis

    to the Fixed and Fixed - Satellite service and on a secondary basis to the Mobile service; b) that current use of the band 3600 - 4200 MHz in most European countries is according to ITU-R

    Recommendation F.635 and/or Recommendation F.382;

    c) that ITU-R Recommendation F.635 only sets a basic raster of 10 MHz without defining a specific

    channel spacing or a duplex spacing;

    d) that ITU-R Recommendation F.382 only uses the band segment 3800-4200 MHz requiring a proposal

    for a harmonisation of the remaining band 3600-3800 MHz;

    e) that in most European countries there is a need for medium and high capacity radio relay systems for

    long range applications and/or the allocation of additional spectrum for P-MP systems in the band 3600-

    4200 MHz;

    f) that the use of the channel arrangements described in Annex A herein for 20/40 MHz channels, results

    in channel 1 in the lower half of the band extending into the adjacent band 3400 - 3600 MHz; g) that frequency separation may be required for un-coordinated deployment of current and future systems;

    h) that cellular deployment of P-MP systems preferably requires the allocation of continuous spectrum to

    the operator;

    i) that frequency allocations in the neighbouring 3400-3600 MHz band will be based on slots of 0.25 MHz,

    according to the ERC Recommendation TR 14-03;

    Edition of May 14, 1998

CEPT/ERC/REC 12-08 E Page 2

recommends

    that CEPT administrations having the band 3600-4200 MHz available for the fixed service should adopt

    channel arrangements in accordance with either:

1) Annex A

     which is based on ITU-R Recommendation F.635 for the frequency range 3600-4200 MHz with channel

    spacings of 40 or 30 MHz and a duplex spacing of 320 MHz;

    or

    2) Annex B

     which is based on ITU-R Recommendation F.382 for the frequency range 3800-4200 MHz and on

    channel and block allocations derived from frequency slots of 0.25 MHz for the remaining band, 3600-

    3800 MHz. This latter band may be used for low capacity P-MP or P-P systems in a manner similar to

    the adjacent band 3400 to 3600 MHz. ”

    PART 2

    Harmonisation of the frequency band 3600 to 3800 MHz;

    for point to point and point to multipoint systems

B2.1: 50 MHz arrangements

B2.1.1 Point to multipoint systems

P-MP systems may be operated in the ranges 3600-3700 MHz and 3700-3800 MHz.

Where a duplex allocation is required, the spacing between the lower edges of the paired sub-bands shall be 50

    MHz.

Frequency assignments should in all cases be based on contiguous sets of 0.25 MHz slots within the 3600 MHz

    to 3800 MHz band,

     the frequency of the lower edge of any slot shall be defined by the general equation:

    f = ( 3600 + 0.25M ) MHz s

     M = 0, 1, 2, 3, 4, ……. 799

    Similar expressions can therefore be used to define the lower edge of each sub-band, while the upper edge of

    each sub-band can be defined by using a second integer, k , as shown in the table below. The purpose of this table is to formalise the description of paired sub-bands given above and to show that both of the sub bands of

    any allocated pair must be within either the 3600 - 3700MHz or 3700-3800 MHz bands. This leaves the

    spectrum management authority free to define the width of each sub band as any multiple of 0.25MHz, from

    0.25 MHz through to 50 MHz.

    3600 - 3700 MHz

    Lower sub-band: 0.25N + 3600 MHz

    to

    0.25(N + k) + 3600

    Upper sub-band: 0.25(N + 200) + 3600 MHz

    to

    0.25(N + k + 200) + 3600 MHz

    1 <= k <= 200,

    0 <= N <= 199,

    k + N <= 200

    3700 - 3800 MHz

    Lower sub-band: 0.25N + 3600 MHz

    to

    0.25(N + k) + 3600

    Upper sub-band: 0.25(N + 200) + 3600 MHz

    to

    0.25(N + k + 200) + 3600 MHz

    1 <= k <= 200,

    400 <= N <= 600,

    k + N - 400 <= 200

    In the tables above, k defines the width of each sub-band and N defines the lower edge of each sub-band.

For example: an allocation of a pair of 15 MHz sub-bands at 3620 - 3635 MHz paired with 3670 - 3685 MHz

    (N=80 and k=60) would meet the recommendation, while a pair of sub-bands at 3620.125 - 3635.125 MHz

    paired with 3670.125 - 3685.125 MHz ((N=80.5 and k=60 ) would not.

P-MP equipment may be used having a duplex spacing other than exactly 50 MHz. However, such equipment

    must conform to the limits of the block allocation as defined above.

B2.1.2 Point to point systems with a duplex spacing of 50 MHz

Channel centre frequencies are defined at the edges of 0.25 MHz slots as follows.

B2.2: 100 MHz arrangements

B2.2.1 Point to multipoint systems

P-MP systems may be operated in the range 3600-3700 MHz paired with 3700-3800 MHz.

Where a duplex frequency allocation is required, the spacing between the lower edges of each paired sub-band

    shall be 100 MHz.

Frequency assignments should in all cases be based on contiguous sets of 0.25 MHz slots within the 3600 MHz

    to 3800 MHz band,

     the frequency of the lower edge of any slot shall be defined by the general equation:

    f = ( 3600 + 0.25M ) MHz s

     M = 0, 1, 2, 3, 4, ……. 799

    Similar expressions can therefore be used to define the lower edge of each sub-band, while the upper edge of

    each sub-band can be defined by using a second integer, k , as shown in the table below. The purpose of this table is to formalise the description of paired sub-bands given above while leaving the spectrum management

    authority free to define the width of each sub band as any multiple of 0.25MHz, from 0.25 MHz through to

    100MHz.

    Lower sub-band: 0.25N + 3600 MHz

    to

    0.25(N + k) + 3600

    Upper sub-band: 0.25(N + 400) + 3600 MHz

    to

    0.25(N + k + 400) + 3600 MHz

    1 <= k <= 400,

    0 <= N <= 400,

    k + N <= 400

    In the tables above, k defines the width of each sub-band and N defines the lower edge of each sub-band.

For example: an allocation of a pair of 15MHz sub bands at 3620-3635 MHz paired with 3720-3735MHz

    (N=80 and k=60) would meet the recommendation, while a pair of sub-bands at 3620.125 - 3635.125 MHz

    paired with 3720.125 - 3735.125 MHz (N=80.5 and k=60) would not.

P-MP equipment may be used having a duplex spacing other than exactly 100 MHz. However, such equipment

    must conform to the limits of the block allocation as defined above.
