Abstract: A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, one of an SRS resource indicator (SRI), a CSI-RS resource indicator (CRI), a synchronization signal block (SSB) identifier, and an uplink transmission configuration indicator (TCI); on the basis of whether the received indicator/identifier includes an indication that the corresponding indicator/identifier is commonly used for an SRS resource group or an indication that the corresponding indicator/identifier is used for a first SRS resource of the SRS resource group, determining whether to use the same transmission beam or use different transmission beams to transmit an SRS in the SRS resource group; on the basis of the determination, determining a transmission beam for the terminal, indicated by the received indicator/identifier; and transmitting the SRS in the first SRS resource on the basis of the transmission beam for the terminal, wherein the SRS resource group includes the first SRS resource and a second SRS resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

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: According to the present invention, transmission power of a preamble for a random access process is determined on the basis of a preamble transmission counter and a downlink path loss estimate value in a wireless communication system. The preamble transmission counter is calculated by using the number of preamble transmissions performed by a user equipment for the random access process, regardless of a random access channel resource. The downlink path loss estimate value is calculated for a synchronization signal linked to the random access channel resource used in transmitting a corresponding preamble. Other downlink path loss estimate values can be calculated for other synchronization signals.

Abstract: Disclosed is a method for transmitting and receiving a channel state information (CSI)-reference signal (RS) in a wireless communication system.
Specifically, the method performed by a base station may include: configuring control information indicating that an antenna port for all CSI-RS resources included in a CSI-RS resource set is same, wherein the CSI-RS resource set is used for tracking at least one of a time or a frequency; transmitting the configured control information to a user equipment (UE); and transmitting the CSI-RS to the UE through all the CSI-RS resources.
In doing so, the UE is capable of performing time/frequency tracking more precisely.

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: A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.
