LTE的EARFCN和band之间的对应关系

一、通过EARFCN查询对应band

工作中经常遇到只知道EARFCN而需要计算band的情况,因此查了相关协议,找到了他们之间的对应关系,可以直接查表,非常方便。

具体见:

3GPP TS 36.101

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 F_{DL\_low} and N_{Offs-DL} are given in Table 5.7.3-1 and N_{DL} is the downlink EARFCN.
    F_{DL} = F_{DL\_low} + 0.1(N_{DL}N_{Offs-DL})

The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where F_{UL\_low} and N_{Offs-UL} are given in Table 5.7.3-1 and N_{UL} is the uplink EARFCN.
    F_{UL}F_{UL\_low} + 0.1(N_{UL}N_{Offs-UL})

NOTE 1: The channel numbers that designate carrier frequencies so close to the operating band edges that the carrier extends beyond the operating band edge shall not be used. This implies that the first 7, 15, 25, 50, 75 and 100 channel numbers at the lower operating band edge and the last 6, 14, 24, 49, 74 and 99 channel numbers at the upper operating band edge shall not be used for channel bandwidths of 1.4, 3, 5, 10, 15 and 20 MHz respectively.

NOTE 2: Restricted to E-UTRA operation when carrier aggregation is configured.

NOTE 3: For ProSe and V2X the corresponding UL channel number are also specified for the DL for the associated ProSe/V2X operating bands i.e. ProSe_FUL = FUL and ProSe_FDL = FUL; V2X_FUL = FDL and V2X_FDL = FUL.

NOTE 4: Requirements for uplink operations are not specified in this version of the specification.

NOTE 5: The range 2180-2200 MHz of the DL operating band  is restricted to E-UTRA operation when carrier aggregation is configured.

NOTE 6: The range 2010-2020 MHz of the DL operating band is restricted to E-UTRA operation when carrier aggregation is configured and TX-RX separation is 300 MHz The range 2005-2020 MHz of the DL operating band is restricted to E-UTRA operation when carrier aggregation is configured and TX-RX separation is 295 MHz.
NOTE 7:    In the present version of the specification, only EARFCN 70686 and 134322 is applicable for 3 MHz channel bandwidth.

从表格5.7.3-1可以看出,知道了EARFCN,我们看它是在Range of N_{DL}的哪一行,就可确定它对应的band了。
