NG Toolset开发笔记--5GNR Resource Grid（50）

ngapp_build20190320放出后，陆续收到反馈：app总是报错，不容易找到valid configuraiton能让工具顺利导出excel。

为方便调试验证，新增下列feature：

（1） 如果options/enable debug勾选，不会再执行excel导出操作，即使configuration是正确的。如果需要导出excel，请去勾选options/enable debug。

（2）针对工具中存在的四处随机操作，新增‘advanced settings' tab用于指定对应参数配置：

这四处随机操作分别是：

（1）recvSSB之后侦听SIB1调度PDCCH occasion时：

*bestSsb为随机选取

*与bestSsb对应的PDCCH slot为随机选取

*与bestSSB对应的PDCCH slot的PDCCH candidate为随机选取

（2）PRACH发送过程中：

*与bestSsb对应的PRACH occasion为随机选取

（3）侦听Msg2调度的PDCCH occasion时：

*pdcch occasion为随机选取；

*与pdcch occasion对应的pdcch candidate为随机选取

'advanced settings'中与上述对应的6个配置参数，用于直接指定相应的配置值。对于invalid configuration，可以通过’advanced settings‘配置来逐步调整为valid configuration。

（3）举例如下：

n41，100M，all scs=30k，ul/dl configuration is align to LTE sa2+ssp7(3:1+10:2:2) with 3ms offset.

第一次执行（注意勾选enable debug）报错：即SIB1与SSB重叠。

tdOverlapped = {32~39, 44~49}；而symbol32~39对应issb=2，symbol 44~49对应issb=3 （注意baseScsTd=60k, ssbScs=30k,所以scaleTd=2；tdOverlapped以及ssbFirstSymb都是以baseScsTd定义的）

sib1时域调度为sfn=0,slot=1,startSymb=2,numSymbs=9

从下面图示可以看出，sib1与ssb时域重叠情况。

为避开ssb，可以将sib1时域调度信息配置为：sfn=0,slot=1,startSymb=12,numSymbs=2

为了实现在上述配置的基础之上，规避上述ssb/sib1重叠错误，可以在'advanced settings'配置：

并将DCI 1_0(SIB1)时域调度从2调整为10：

再次执行时，又提示msg2与ssb冲突：

tdOverlapped={4~11, 16~17}，其中symbol4~11对应issb=0，symbol 16~17对应issb=1

Msg2时域调度信息为：sfn=2,slot=0,startSymb=2,numSymbs=7

同理如果将Msg2时域调度从3调整为10也可以解决冲突：此时startSymb=12，numSymbs=2。

为进一步规避msg2/ssb冲突问题，将'advanced settings'配置为：

并将DCI 1_0(Msg2)的时域调度从3调整为10：

此时配置已ok：
