例如WCDMA Band1的信从9612到9888,请问为什么要这么定义。为什么不从9000开始?
信道定义是信道频率乘5,就是信道号
3GPP里的定义:
The carrier frequency is designated by the UTRA Absolute Radio Frequency Channel Number (UARFCN). For each
operating Band, the values of the UARFCN 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
明白了,多谢小编

明白了
多谢...
曾经有过一个面试,面试官问我WCDMA频率范围多少,没答出来,汗!
晕,W频段N多,谁记得住啊,那个面试官牛逼
