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.

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: A method and apparatus for supporting a hybrid mode positioning scheme in a wireless communication system is provided. While using a first positioning mode, a user equipment (UE) receives information on a triggering condition for the positioning mode switch from a network, i.e. an evolved serving mobile location center (E-SMLC). The UE determines that the triggering condition is satisfied, and switches the positioning mode from the first positioning mode to a second positioning mode.

Abstract: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

Abstract: Provided are a method for a terminal for requesting a system information block (SIB), and an apparatus for supporting the method in a wireless communication system. The method may comprise the steps of: receiving, from a radio access network (RAN), an SIB list comprising one or more SIBs supported by a cell; receiving, from the RAN, SIB broadcast information indicating whether the SIB supported by the cell is broadcast in a broadcast control channel (BCCH) section; detecting an omitted SIB on the basis of the SIB list and SIB broadcast information; and requesting the omitted SIB from the RAN.

Abstract: Provided are a method for requesting, by a user equipment (UE), system information in a wireless communication system and a device supporting the same. The method may include: initiating a random access procedure; requesting system information from a base station (BS) in the initiated random access procedure; receiving, from the BS, a broadcast indication indicating that the requested system information is broadcast in the initiated random access procedure after requesting the system information from the BS; and stopping the initiated random access procedure.

Abstract: A method for processing signals by a user equipment (UE) in a Wireless communication system is disclosed. The method includes steps of transmitting, to a network, a request message for configuring a time resource in which a transmission of a message via a sidelink is prioritized over a transmission of an uplink message and a reception of a downlink message; receiving, from the network, a configuration message as a response of the request message; and transmitting the V2X message in the time resource via the sidelink.
