I also met such issue.

Some points:

  • What is the frame configuration? Sub frame configuration - it’s in cell if you are using Huawei check it it’s normally sa0 and sa7 for TDD check if it’s OK
  • Check smart preallocation is it open or not?
  • Check UL synch users is it high or not
  • If closed loop mimo is activated with DL FSS , close FSS (Frequency Selective schedule)
  • In FDD normally we use ol adaptive with tm3
  • What’s the HARQ and BLER?
  • Also the buffer status?
  • FSS is Frequency selective scheduling. You can find it in cellalgoswithch
