LTE频点计算公式及频点号对应表

LTE频点计算公式下行频点计算公式：FDL=FDL_low+0.1(NDL–NOffs-DL)其中FDL为该载频下行频点，FDL_low对应频段的最低下行频点，NDL为该载频下行频点号，NOffs-DL对应频段的最低下行频点号。对应关系表详见表5.7.3-1。上行频点计算公式：FUL=FUL_low+0.1(NUL–NOffs-UL)其中FUL为该载频上行频点，FUL_low对应频段的最低上行频点，NUL为该载频上行频点号，NOffs-UL对应频段的最低上行频点号。对应关系表详见表5.7.3-1。上下行频点号范围：0-65535.对应关系表详见表5.7.3-1如下：电信目前可能分配FDD频段，给你的EARFCN是1750，则范围落在RangeofNDL的band3（1200-1949）中，需要使用BAND3的参数进行计算UTRAOperatingBandDownlinkUplinkFDL_low[MHz]NOffs-DLRangeofNDLFUL_low[MHz]NOffs-ULRangeofNUL1211000–59919201800018000–1859921930600600-119918501860018600–191993180512001200–194917101920019200–19949按照公式：FDL=FDL_low+0.1(NDL–NOffs-DL)FDL=1805+0.1*(1750-1200)=1860M是下行的中心频点。NDL=10*(FDL–FDL_low)+NOffs-DLFDL:中心频率Table5.7.3-1:E-UTRAchannelnumbersE-UTRAOperatingBandDownlinkUplinkFDL_low[MHz]NOffs-DLRangeofNDLFUL_low[MHz]NOffs-ULRangeofNUL1211000–59919201800018000–1859921930600600119918501860018600–191993180512001200–194917101920019200–199494211019501950–239917101995019950–20399586924002400–26498242040020400–20649687526502650–27498302065020650–207497262027502750–344925002075020750–21449892534503450–37998802145021450–2179991844.938003800–41491749.92180021800–2214910211041504150–474917102215022150–22749111475.947504750–49491427.92275022750–229491272950105010–51796992301023010–231791374651805180–52797772318023180–232791475852805280–53797882328023280–23379…1773457305730–58497042373023730–238491886058505850–59998152385023850–239991987560006000–61498302400024000–241492079161506150-64498322415024150-24449211495.964506450–65991447.92445024450–2459922351066006600-739934102460024600-2539923218075007500–769920002550025500–2569924152577007700–80391626.52570025700–2603925193080408040-868918502604026040-266892685986908690–90398142669026690-270392785290409040–92098072704027040–272092875892109210–96597032721027210–2765929271796609660–9769N/A…3319003600036000–3619919003600036000–361993420103620036200–3634920103620036200–363493518503635036350–3694918503635036350–369493619303695036950–3754919303695036950–375493719103755037550–3774919103755037550–377493825703775037750–3824925703775037750–382493918803825038250–3864918803825038250–386494023003865038650–3964923003865038650–396494124963965039650–4158924963965039650–415894234004159041590–4358934004159041590–435894336004359043590–4558936004359043590–45589447034559045590–465897034559045590–46589NOTE1:Thechannelnumbersthatdesignatecarrierfrequenciessoclosetotheoperatingbandedgesthatthecarrierextendsbeyondtheoperatingbandedgeshallnotbeused.Thisimpliesthatthefirst7,15,25,50,75and100channelnumbersattheloweroperatingbandedgeandthelast6,14,24,49,74and99channelnumbersattheupperoperatingbandedgeshallnotbeusedforchannelbandwidthsof1.4,3,5,10,15and20MHzrespectively.NOTE2:RestrictedtoE-UTRAoperationwhencarrieraggregationisconfigured.
