Abstract: A method and apparatus for transmitting a time-critical message in a wireless communication system is provided. A user equipment (UE) (e.g. vehicle UE (V-UE)) receives a grant of resources in a resource pool for the time-critical message from a network (e.g. eNodeB (eNB) or a road side unit (RSU) for vehicle-to-everything (V2X) communication), and transmits the time-critical message by using the granted resources to another UE. The time-critical message may correspond to V2X communication.

Abstract: The present invention relates to a wireless access system supporting machine type communication (MTC), and to various methods for an MTC terminal transmitting/receiving data. A method for an MTC terminal receiving data in a wireless access system supporting MTC, as one embodiment of the present invention, may comprise the steps of: receiving a modulation and coding scheme (MCS) index indicating a MCS, and a physical resource block (PRB) index indicating the size of a PRB allocated to a MTC terminal; checking a transport block size (TBS) index that is mapped with the MCS index and deriving a TBS on the basis of the TBS index and the PRB index; and on the basis of the TBS, decoding a physical downlink shared channel (PDSCH) in order to receive data. Here, the size of the MCS index is configured to be a 4-bit size, and the TBS index may be configured so as to support only from 0 to 9 for the MTC terminal.
