相关配置如下（还有的地方不知道如何修改，目前改成202后，UE端显示： RAR reception failed
）：
#rach-ConfigGeneric
prach_ConfigurationIndex = 202;
#prach_msg1_FDM
#0 = one, 1=two, 2=four, 3=eight
prach_msg1_FDM = 0;
prach_msg1_FrequencyStart = 0;
zeroCorrelationZoneConfig = 13;
preambleReceivedTargetPower = -76;
#preamblTransMax (0...10) = (3,4,5,6,7,8,10,20,50,100,200)
preambleTransMax = 6;
#powerRampingStep
# 0=dB0,1=dB2,2=dB4,3=dB6
powerRampingStep = 2;
#ra_ReponseWindow
#1,2,4,8,10,20,40,80
ra_ResponseWindow = 6;
#ssb_perRACH_OccasionAndCB_PreamblesPerSSB_PR
#1=oneeighth,2=onefourth,3=half,4=one,5=two,6=four,7=eight,8=sixteen
ssb_perRACH_OccasionAndCB_PreamblesPerSSB_PR = 4;
#oneHalf (0..15) 4,8,12,16,...60,64
ssb_perRACH_OccasionAndCB_PreamblesPerSSB = 14;
#ra_ContentionResolutionTimer
#(0..7) 8,16,24,32,40,48,56,64
ra_ContentionResolutionTimer = 7;
rsrp_ThresholdSSB = 19;
#prach-RootSequenceIndex_PR
#1 = 839, 2 = 139
prach_RootSequenceIndex_PR = 2;
prach_RootSequenceIndex = 1;

您好，我参考的是这个表格起始位置是756行，根据序号202，应该是对应958行。对应的是0xc2。这个不应该是C2吗？
