1-30开始NB-IoT资源栅格开发。NgNbiotGrid基于NgLteGrid开发，主要实现inband模式。第一步是，调整NgLteGrid输出csv中time/frequency的索引方式，从base10调整为base36time domain：格式为[AABBCD]，AA为HSFN，BB为SFN，C为subframe，D为symbolfrequency domain：格式为[

第二步是UI设计，包含4个tab：Host LTE、NB-IoT Common、NB-IoT UL和NB-IoT DL。比如nbiot ul tab：NB UL carrier对应PRB位置，缺省为紧挨着上端PRACH放置。NB DL carrier的PRB位置由界面配置。原LTE Grid更新如下：UL/DL Grid中对应NB UL/DL carrier的PRB标记为NB UL和N

开发NG Toolset的目的有2个：（1） 、将原来LTE Toolset V1/V2的部分工具，用Python重写；（2）、增加5GNR的部分工具。长期计划是探索与构造Deep Learning在RAN NPO中的应用。因为LTE Toolset V1/V2使用Qt/C++实现的，所以NG Toolset的UI会用PyQt实现：'''ngmainwin.py''

首先是ui部分，ngltegridui.pyclass NgLteGridUi(QDialog): def __init__(self, ngwin): super().__init__() self.ngwin = ngwin self.args = dict() self.initResGridMapper()

coding完毕，举例NgLteGrid.fillSrs实现如下：def fillSrs(self): #Note: Since srs has many ue-specific parameters, such as frequency bandwidth and offset and ue-specific subframe config. #so we j
