1.5G(NR)網(wǎng)絡中信道帶寬整理:kangguoying20200619

        3GPP在協(xié)議38.101-1,圖5.3.3-1對5G(NR)網(wǎng)絡中信道帶寬和傳輸帶寬進行了定義；整理:kangguoying20200619

        信道帶寬（Channel BW=最大傳輸帶寬+保護帶寬（兩側）；其中：最大傳輸帶寬是RB；而保護帶寬單位為khz;

2.5G(NR)網(wǎng)絡信道帶寬計算公式整理:kangguoying20200619

        信道帶寬（CBW）=N_RB*子載波數(shù)*子載波間隔+保護帶寬*2；其中：整理:kangguoying20200619

        N_RB最大傳輸帶寬  查：38.101-1表5.3.2-1；38.101-2表5.3.2-1整理:kangguoying20200619

        子載波數(shù)=12（常數(shù)）整理:kangguoying20200619

        子載波間隔  查：38.101-1表5.3.2-1；38.101-2表5.3.2-1整理:kangguoying20200619

        保護帶寬  查：38.101-1表5.3.3-1,38.101-2表5.3.3-1整理:kangguoying20200619

 舉例：

             CBW=5Mhz，SCS=30Khz整理:kangguoying20200619

             N_RB* NumOfSubcarrier* SCS =11*12*30=3960(kHz)  （a）整理:kangguoying20200619

             GuardBand x 2= 505 x 2 = 1010                        （b）整理:kangguoying20200619

            （a）+（b）=3960+1010=4970kHz = 4.970 Mhz接近5 Mhz CBW整理:kangguoying20200619
