Abstract: A method and apparatus for controlling congestion of contention based uplink (UL) transmission in a wireless communication system is provided. A user equipment (UE) receives at least one of a backoff parameter or probability information for contention based UL transmission, i.e. contention based physcial uplink shared channel (CB-PUSCH) transmission and contention based scheduling request (CB-SR) transmission, from a network, and delays the contention based UL transmission based on the at least one of the backoff parameter or the probability information.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) performs a contention free random access procedure on a first frequency, detects a failure of the contention free random access procedure, and performs a contention based random access procedure. When the first frequency is occupied by other media as a result of listen-before-talk (LBT) operation, the contention based random access procedure may be performed on a second frequency.

Abstract: A method is provided for operating by a user equipment (UE) connected with a master base station (BS) and a secondary BS in a wireless communication system. The UE configures a first cell supporting a contention based random access and a second cell other than the first cell. The first cell and the second cell are associated with the secondary BS. The UE determines whether a radio link problem is occurred on the first cell or the second cell. The UE indicates the radio link problem to an upper layer only if the radio link problem occurs on the first cell.
