Scope of recommendation
Radio frequency channel arrangements for the FS operating in the bands 71-76 GHz and 81-86 GHz
| Annex | Frequency Bands | FDD and/or TDD | P-P and/or P-MP | Notes |
|---|---|---|---|---|
| 1 (used for FDD or TDD) | 71000 MHz - 76000 MHz | FDD or TDD | P-P | The specified channels may be used to form either TDD or FDD systems within the single band, or in combination with other band specified in this recommendation. A number of contiguous individual channels with 250 MHz separation maybe further subdivided into 62.5 or 125 MHz channels. |
| 2 (TDD or FDD) | 81000 MHz - 86000 MHz | FDD or TDD | P-P | The specified channels may be used to form either TDD or FDD systems within the single band, or in combination with other band specified in this recommendation. A number of contiguous individual channels with 250 MHz separation maybe further subdivided into 62.5 or 125 MHz channels. |
| 3 (FDD) | 71000 MHz - 76000 MHz and 81000 MHz - 86000 MHz | FDD | P-P | FDD arrangements with lower duplex separation than 10 GHz may be in place. When wider channels are needed, consecutive 250 MHz channels may be aggregated. |
| Note 1 | PP links in these bands be assigned or recorded on a link-by-link basis or with block assignment provided that inter block compatibility is ensured. When extremely high bit rate system is required, administrations considering Annex 1 or Annex 2 may allow flexible aggregation of those 250 MHz basic channels for composing wider channels. Administrations wishing to assign pre-defined channels of multiple size, either paired or unpaired, may consider the channel arrangements illustrated in Annex 4. Administration wishing to allocate smaller channels, may subdivide those 250 MHz basic channels into multiples 62.5 MHz sub-channels as illustrated in Annex 1, 2 and 4. |
