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.

Abstract: A method performed by a wireless device in a wireless communication system includes receiving multiple thresholds from a base station (BS); measuring a quality of a cell; determining a coverage enhancement (CE) level of the wireless device based on the multiple thresholds and the measured quality of the cell; receiving random access channel (RACH) information including at least one window size value and at least one timer value for contention resolution, from the BS; selecting a window size value and a timer value among the RACH information based on the determined CE level; transmitting a first message for the RACH to the BS; receiving a second message for the RACH based on the selected window size value, from the BS; and starting a timer for contention resolution based on the selected timer value regarding a third message for the RACH. Further, the CE level is determined as a CE level 0, when the measured quality is above or equal to all of the multiple thresholds.
