Abstract: A method and apparatus for switching between unicast and multicast in a wireless communication system is provided. A DU of a RAN node provides the MBS by using a first transmission to the wireless device. A DU of a RAN node receives, from the wireless device, feedback information in response to the provided MBS. A DU of a RAN node transmits, to a central unit (CU) of the RAN node, a first switching message based on the received feedback information. A DU of a RAN node receives, from the CU, a second switching message to switch the first transmission to the second transmission for the MBS. A DU of a RAN node provides the MBS by using the second transmission to the wireless device.

Abstract: A method and apparatus for channel access priority classes based on message type in a wireless communication system is provided. A wireless device obtains mapping information between message types and Channel Access Priority Classes (CAPCs). A wireless device detects a message to be transmitted. A wireless device selects a specific CAPC for the message based on the mapping information. A wireless device performs LBT procedure based on the specific CAPC. A wireless device transmits, to a second device, the message after the LBT procedure.

Abstract: A method and apparatus for random access procedure based on a beam quality in a wireless communication system is provided. A wireless device monitors a paging including information on one or more beams associated with a contention free random access procedure and selects at least one beam of which a quality is above a threshold among the one or more beams. The wireless device performs the contention free random access procedure via the at least one beam. When there is no beam of which the quality is above the threshold, the wireless device performs a contention based random access procedure.
