Hello everyone,

I'm having a hard time understanding the concept of how to configure slot patterns. More specifically, I'm simulating a bandwidth of numerology 3 and setting a pattern of F|F|UL|UL|UL|UL|UL|UL| to focus the channel more towards UL signals. If I add or remove an extra slot to the pattern I will either get one of these two error messages:
  • NS_ASSERT failed, cond="m_ctrlMsgs.empty()"
  • NS_ASSERT failed, cond="symUsed == allocInfo.m_numSymAlloc", msg="Allocated 15 but only 10 written in stats"
Can someone please help me to understand what these error messages are stating and overall what I need to be aware of in order to configure a pattern correctly under a specific numerology?

Thanks in advance,

I need more information to reproduce. For me, setting numerology 3 and 2xF+8xUL is working just fine.
Are you using one of the examples? If yes, give me all the parameters.
If not, but you can share the source file and how to reproduce, share it.
