关于NB-IOT的，里面看到NDSCH, NPUSCH, TBS不知道是什么意思，网上查了下没有能对上的。
刚开始接触，可能是常识，原文前面也没有说明。。。
原文如下
NDSCH peak data rate can be achieved by using the largest TBS of 680 bits and transmitting it over 3 ms [10]. This gives 226.7 kb/s peak layer 1 data rate. NPUSCH peak data rate can be achieved by using the largest TBS of 1000 bits and transmit- ting it over 4 ms [10]. This gives 250 kb/s peak layer 1 data rate. However, the peak throughputs of both downlink and uplink are lower than the above figures when the time offsets between DCI, NPDSCH/NPUSCH, and HARQ acknowledg- ment are taken into account.
