3GPP TS 25.101 V9.5.0 (2010-09)
Channel number
The carrier frequency is designated by the UTRA Absolute Radio Frequency Channel Number (UARFCN). For each operating Band, the UARFCN values are defined as follows:
Uplink: NU = 5 * (FUL - FUL_Offset), for the carrier frequency range FUL_low FUL FUL_high
Downlink: ND = 5 * (FDL - FDL_Offset), for the carrier frequency range FDL_low FDL FDL_high
For each operating Band, FUL_Offset, FUL_low FUL_high, FDL_Offset,, FDL_lowand FDL_high are defined in Table 5.1 for the general UARFCN. For the additional UARFCN, FUL_Offset, FDL_Offset and the specific FUL and FDL are defined in Table 5.1A.
