Abstract: A method for a terminal receiving a beam reference signal (BRS) and a physical broadcast channel (PBCH) in a wireless communication system can comprise the steps of: determining a power ratio of BRS to PBCH per resource element (RE) on the basis of the number of BRS ports; detecting the BRS and a demodulation reference signal (DMRS) on the basis of the number of the BRS ports; and determining whether or not the determined power ratio of BRS to PBCH is to be compensated to an estimated channel on the basis of the DMRS.

Abstract: Disclosed are an information transmission method and terminal for: determining from a base station that a beam mismatch has occurred; transmitting a terminal-specifically allocated RACH preamble to the base station in order to transmit beam-related information indicating that the beam mismatch to the base station; receiving, from the base station, a message (for example, RACH response) for requesting transmission of the beam-related information; and transmitting uplink control information including the beam-related information to the base station.

Abstract: A method for generating an SRS sequence by a terminal may comprise the steps of: calculating a first root value for generation of an SRS sequence of a first block among concatenated blocks configured for transmission of an SRS, using a terminal-specific SRS identifier; calculating a second root value for generation of an SRS sequence of a second block on the basis of the calculated first root value and a root offset value; and generating an SRS sequence for transmission of an SRS on the concatenated blocks by applying the first root value to the first block and applying the second root value to the second block.

Abstract: The present invention provides a method for determining a modulation and coding scheme (MCS) to be applied to data in a wireless communication system, and a device therefor. Specifically, the method may comprise the steps of: reporting, to a base station, channel state information including a first measurement value related to a channel state between a terminal and the base station; receiving at least one downlink reference signal from the base station; calculating a second measurement value related to the channel state by using the received at least one downlink reference signal; when the second measurement values is equal to or smaller than a preconfigured threshold value in comparison with the first measurement value, transmitting, to the base station, a specific uplink signal requesting a change of an MCS designated to downlink data; and receiving the downlink data, to which the changed MCS has been applied, from the base station.

Abstract: The present invention relates to a method and a device for allowing a terminal to perform decoding in a wireless communication system. According to the present invention, provided are a method and a device for receiving, from a base station through DMRS symbols, a first demodulation reference signal (DMRS) and a second DMRS, which are set according to specific patterns, wherein: each of the first DMRS and the second DMRS is transmitted on a specific antenna port and is located on the same time axis symbol as at least one different DMRS transmitted on the other antenna port; a location of the time axis symbol of the second DMRS is determined according to a service type of transmitted data; and the data are decoded by using the first DMRS and/or the second DMRS.
