NEW QUESTION 36
Regarding random access, which of the following situations may be used for non-competitive random access?
- A. When the UE performs handover, the UE initiates random access in the target cell.
- B. When the UE is in the connected state, the uplink data arrives for some reason (the UE thinks that its uplink is out of step) and needs random access.
- C. When the UE is in the connected state, the downlink data arrives for some reason (the ENB thinks that the UE is out of step) requires random access.
- D. Because the wireless link conditions are not good (failure), the RRC connection is reestablished, and the UE initiates random access.
