Abstract: Disclosed are a method and device for performing random access in a wireless communication system. The method for performing, by a terminal, a random access procedure in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving, from a base station, information about a modulation and coding scheme (MCS) index group for a message 3 physical uplink shared channel (Msg3 PUSCH), on the basis that repetition transmission for the Msg3 PUSCH is configured, the MCS index group comprising at least one MCS index value; receiving, from the base station, MCS information indicating a specific MCS index value among the at least one MCS index value; and transmitting the Msg3 PUSCH on the basis of the specific MCS index value indicated by the MCS information.

Abstract: The present specification relates to a reception apparatus and method for demodulating a signal in a wireless AV system. The reception apparatus estimates a transmission signal on the basis of an MMSE weight matrix. The reception apparatus divides the estimated transmission signal for respective reception antennas and performs an IFFT. The reception apparatus estimates and compensates for phase noise for the respective reception antennas on the basis of the signal for which the IFFT has been performed. The reception apparatus demodulates the estimated and compensated signal for respective streams.
