Abstract: A method and device for transmitting and receiving a signal in a wireless communication system, disclosed in the present specification, distinguish a first purpose radio resource configured as a dedicated resource for one terminal, and a second purpose radio resource commonly configured for terminals in a serving cell. A terminal uses the first purpose radio resource first. Thereby, resource allocation for the plurality of terminals can be flexibly performed while preventing latency due to data jitter.
