Packets transfer in NSA

Hi Experts, have query on one scenario:

  1. NSA.
  2. UE attached to LTE cell and added 4 NR cells.
  3. Now if network sends ping packets, will the ping packets be transferred in all the 4 NR cells OR ping packets will be transferred in NR1 and MAC padding will be done in NR2->NR4?
  1. I guess you mean mmWave NR cells (NSA with 4 NR cells)
  2. very likely NR scheduler implementation will be vendor specifitc, i.e. for small amount of data PDSCH only on 1 NR carrier and no data scheduled on other NR carriers
