- MAC creates CellGroupConfig and sends to RRC - the RRC does not manually update the CellGroupConfig - MAC handles the RRC processing timer In this commit, any updates to the CellGroupConfig previously done at the RRC don't work. In other words, MIMO etc don't work; this is implemented in the next commit. Note that the change to take out spCellConfig during reestablishment is because after reestablishment, as per spec (38.331 5.3.7.2), the UE should drop the spCellConfig, which we generate by default on the first UE connection. Furthermore, add a new variable apply_cellgroup to signal if, after RRC processing timer, we wish to apply the CellGroup. In some situations, e.g., Msg.4 ack, we do not want to apply the CellGroup, because for instance in reestablishment, we await for a reconfiguration of cellgroup that would be triggered too early.
