Abstract: The present specification relates to a method for setting up a bearer in a wireless communication system, carried out by a first base station, comprising the steps of: receiving, from a network entity, a first message requesting to set up an E-UTRAN radio access bearer (E-RAB) for a mission critical service (MCS); transmitting, to the at least one second base station, a second message requesting to set up an alternative link with the terminal, based on the received first message; and receiving, from the at least one second base station, a response message to the second message.

Abstract: The present invention relates to a method and a device for transmitting and receiving data in a wireless communication system. The present invention can provide a method and a device for transmitting to a network node a first preamble and a first request message for requesting random connection; as a response to the first request message, receiving a first response message comprising the index of a second preamble successfully received by the network node and a second identifier for indicating whether or not the first request message is decoded and contention resolution; and, while the connection with the network node has not been formed, transmitting first data to the network node in accordance with the index of the second preamble and the second identifier.

Abstract: The present invention relates to a method and a device for transmitting and receiving data by a terminal in a wireless communication system. The present invention provides a method and a device for: selecting a particular preamble from a preamble set; transmitting the selected particular preamble to a base station by means of resources on the frequency axis and resources on the time axis; receiving from the base station a response message comprising resource information that indicates resources allocated on the basis of a first random connection target of a first terminal; and transmitting, to the base station by means of the allocated resources, verification information of the first terminal for uplink data reception or downlink data reception.
