    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: Disclosed are a method for transmitting and receiving a radio signal in a wireless communication system and an apparatus therefor. Particularly, a method for performing, by a terminal, channel state information (CSI) reporting in a wireless communication system comprises the steps of: receiving, from a base station, bandwidth part (BWP) configuration information on a BWP for uplink and/or downlink transmission; receiving, from the base station, reporting configuration information including a reporting configuration for the CSI reporting; and performing the CSI reporting on the basis of the BWP configuration information and the reporting configuration information, wherein the reporting configuration is associated with the BWP, and whether or not the reporting configuration is activated may be determined on the basis of whether or not the BWP is activated.

    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.

    Abstract: Disclosed is a method for a terminal for transceiving a signal with a base station in a wireless communication system. Specifically, the method comprises the steps of: receiving, from the base station, information regarding one or more extended subbands by means of a base subband; transmitting a random access preamble to the base station by means of a particular extended subband from among the base subband or one or more extended subbands; receiving, from the base station, a random access response corresponding to the random access preamble by means of the particular extended subband; and transmitting an uplink signal and receiving a downlink signal by means of the particular extended subband, wherein the base subband and said one or more extended subbands differ from each other by one or more from among the subcarrier spacing, unit scheduling time, and bandwidth.

    Abstract: Provided are a method and a device for setting a space division connection between terminals for V2X communication in a wireless communication system. Specifically, a second terminal requests a connection setting with a first terminal from a base station. The second terminal measures a signal of the first terminal and generates a first beam group pair comprising a transmission beam group of the first terminal, which has a large signal size, and a reception beam group of the second terminal. When the second terminal receives a signal of a third terminal by using the reception beam group of the second terminal, the second terminal measures a signal of the third terminal and generates a second beam group pair comprising a transmission beam group of the third terminal, which has a large signal size, and the reception beam group of the second terminal.
