Abstract: As a channel busy ratio (CBR) is defined to measure the congestion of a PC5 interface in order to support an effective vehicle-to-everything (V2X) communication, an eNodeB (eNB) transmits CBR information of a sidelink channel to a user equipment (UE) for each resource pool used for V2X communication. The user equipment which has received the CBR information determines if there is a usable CBR and, if it is determined that there is no usable CBR, can use the received CBR information.

Abstract: A method and apparatus for handling coexistence with a dedicated short range communication (DSRC) carrier in a wireless communication system is provided. A user equipment (UE) obtains a first congestion level on a resource set for a first radio technology, determines a second congestion level for the first radio technology by applying an offset to the first congestion level when a second radio technology which shares the resource set with the first radio technology is identified, selects a carrier based on the second congestion level for the first radio technology, and performs transmission on the selected carrier.

Abstract: Provided are an operation method in accordance with uplink semi-persistent scheduling (SPS) of a terminal in a wireless communication system and a terminal using the method. The method is characterized by: receiving, from a base station, downlink control information (DCI) for indicating activation or release of uplink SPS; and decoding the DCI on the basis of a first radio network temporary identifier (RNTI) or a second RNTI. If the DCI is a first DCI for SPS for transmitting a signal to the base station, the DCI is decoded on the basis of the first RNTI, and, if the DCI is a second DCI for SPS for transmitting a vehicle-to-everything (V2X) signal, the DCI is decoded on the basis of the second RNTI. And the first RNTI and second RNTI are RNTIs that are different from each other.

Abstract: Provided are: a method by which a terminal transmits a system information request in a wireless communication system; and a device for supporting the same. The method comprises the steps of: receiving, from a first cell, a list of a frequency and a cell to which a system information request can be transmitted; and determining whether to transmit, to the first cell, the system information request on the basis of the list, wherein the system information request can be transmitted only to a cell included in the list or to a cell using a frequency included in the list.

Abstract: Disclosed are a method by which a terminal receives an MBMS service and an apparatus for supporting the same. The method comprises the steps of: determining a coverage enhancement (CE) level of the terminal in a frequency at which an MBMS service of interest is provided; receiving a CE level of the MBMS service supported by a network; determining whether the MBMS service can be received by comparing the CE level of the terminal with the CE level of the MBMS service; and reporting, to the network, the CE level of the terminal or the number of iterations, which is indicated by the CE level of the terminal, required for the terminal when it is determined that the MBMS service cannot be received.

Abstract: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: A method for discarding at least one packet by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of storing the at least one packet received from an upper layer in a buffer; determining whether or not a number of packets in the buffer is equal to or greater than a threshold value; and discarding the at least one packet from the buffer when the number of packets in the buffer is equal to or greater than the threshold value.

Abstract: One embodiment of a modification of a semi-persistent scheduling (SPS) operation triggered by a terminal in a wireless communication system may be a single hybrid automatic repeat request (HARQ) process according to a plurality of SPS configurations. In other words, an eNodeB (eNB) can provide, to a UE, the plurality of SPS configurations covering a variety of message sizes. Another embodiment of a modification of an SPS operation triggered by a terminal may be a negative acknowledgement (NACK) with respect to a single HARQ process according to a plurality of SPS configurations and an SPS resource grant. In other words, an eNB provides, to a UE, the plurality of SPS configurations covering a dynamic reconfiguration of a message generation period, and whenever a specific SPS resource grant is not used for transmission, the terminal can transmit the NACK with respect to the SPS resource grant.
