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.

Abstract: In a wireless communication system, a user equipment (UE) may reselect a sidelink resource to be used for vehicle-to-everything (V2X) communication. The reselection of sidelink resource may be triggered by various conditions. In particular, the reselection of the sidelink resources may be triggered when a value of sidelink resource reselection counter is zero. More specifically, the UE determines that data for the V2X communication is available in a sidelink traffic channel (STCH), determines that a value of the sidelink resource reselection counter is zero, and reselects the sidelink resources.
