Abstract: Provided is a method for a terminal performing a random access procedure in a wireless communication system. The method comprises the steps of: transmitting, to a base station, a first random access preamble corresponding to a system information block-of-interest; receiving, from the base station, a random access response including a random access preamble identifier, wherein the random access preamble identifier indicates a second random access preamble; and determining that the random access response is valid for the terminal if the second random access preamble is included in the same preamble group as the first random access preamble.

Abstract: A method and an apparatus for reporting an ID of specific BWP among the multiple BWPs in a wireless communication system is provided. The method, by a UE, may include configuring multiple bandwidth parts (BWPs) including at least one of an active bandwidth part (BWP), receiving a received signal strength indicator (RSSI) measurement configuration and/or a channel occupancy measurement configuration from the network, performing a RSSI measurement and/or a channel occupancy measurement per each of the multiple BWPs, and reporting an identifier (ID) of a specific BWP among the multiple BWPs to the network when a condition related to the RSSI measurement and/or the channel occupancy measurement of the active BWP and the specific BWP is met.

Abstract: Provided are a method for receiving, by a terminal, data on an unlicensed band in a wireless communication system, and an apparatus for supporting the same. The terminal receives, from a base station, a first indicator which indicates existence of data to be transmitted to the terminal; receives a timer value from the base station; performs channel sensing in a section where a timer operates; and can transmit, to the base station on the basis of the result of performing channel sensing, either one of a second indicator, which indicates that reception of data is possible, and a third indicator, which indicates that reception of data is impossible.

Abstract: Provided are a method for applying a load-specific offset by a terminal in a wireless communication system and a device supporting same. A terminal can receive BSS load information from a WLAN AP, calculate a load-specific offset on the basis of the BSS load information, and apply the load-specific offset to a measurement report-inducing event.

Abstract: A method and apparatus for performing a random access procedure at a cell on an unlicensed carrier in a wireless communication system is provided. A user equipment (UE) transmits a random access preamble, and receives a random access response including an index of a second cell. A first cell is a first serving cell on a licensed carrier, and the second cell is a second serving cell on the unlicensed carrier.

Abstract: Provided are a method of reselecting a cell by a terminal in a wireless communication system and a device supporting the same. A terminal may measure a cell on the basis of a priority, may calculate a ranking of the cell, using a cell measurement result, and may reselect a cell having the highest ranking. Otherwise, the terminal may measure a cell and evaluate a cell reselection criterion on the basis of a priority, may calculate a CE level with respect to a cell satisfying the cell reselection criterion evaluation, using a cell measurement result, and may reselect a cell having the lowest CE level. The terminal may be a terminal operating in a coverage extension mode and the coverage extension mode enables the cell measurement to be performed for a longer time than a normal mode.

Abstract: Provided is a method for reporting multimedia broadcast and multicast service (MBMS) information by a terminal in a wireless communication system. The method comprises: determining whether or not to perform the logging of MBMS information; logging the MBMS information if the logging is determined to be performed; and reporting the logged MBMS information to a network. Whether or not to perform the logging of the MBMS information is determined on the basis of the reception status or provision status of MBMS from the network.

Abstract: A method and apparatus for indicating a logged multimedia broadcast multicast service (MBMS) measurement availability in a wireless communication system is provided. A user equipment (UE) determines whether to inform a serving cell that the UE has logged MBMS measurement results to be reported based on a first condition and a second condition, and when both the first condition and the second condition are met, the UE informs the serving cell that the UE has the logged MBMS measurement results. The first condition corresponds to that the UE 0has the logged MBMS measurement results to be reported. The second condition includes at least one MBMS minimization of drive tests (MDT) related condition.

Abstract: A method and apparatus for requesting a unicast bearer setup in a wireless communication system is provided. A user equipment (UE) receives a unicast request indication, which indicates that a target cell does not provide a multimedia broadcast multicast service (MBMS) service in which the UE is interested to the UE, from a network. Upon receiving the unicast request indication, the UE transmits a unicast bearer setup request to the network.
