Abstract: Provided are a method for receiving data in a wireless communication system and a device using same. A device receives a code block from one cell among configured multiple cells. If a decoding error of the code block is detected, the device stores a part of or all of the code block in a receiver buffer. The number of coded bits of the code block stored in the receiver buffer is determined on the basis of the maximum modulation order supported by the cell from which the code block is received.
