    摘要： The present disclosure relates to a method and a device for a terminal transmitting a reference signal in a wireless communication system. According to the present disclosure, a method and a device may be provided, the method comprising: receiving, from a base station, configuration information associated with a configuration of a first demodulation reference signal for demodulating uplink data; and on the basis of the configuration information, transmitting the first demodulation reference signal and the uplink data to the base station via at least one antenna port, wherein the first demodulation reference signal and the uplink data are transmitted in a sub frame by means of frequency hopping, and the first demodulation reference signal is positioned on the same time axial symbol as that of at least one other demodulation reference signal transmitted on another antenna port.

    摘要： A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, information on a first bandwidth part (BWP) and a second BWP set for SRS transmission of the terminal; and when a frequency starting position for SRS transmission in the second BWP having a lower priority than the first BWP overlaps the first BWP, transmitting the SRS to the base station at an SRS bandwidth position different from an SRS bandwidth position associated with the frequency starting position for the SRS transmission. 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.

    摘要： A method for receiving a downlink channel by a terminal in a wireless communication system and a device therefor. More particularly, a method includes: receiving, from a base station, configuration information relating to a plurality of transmission beams of the base station, wherein the configuration information includes configuration items with respect to one or more beam sets including the plurality of transmission beams; receiving information indicating any one beam set among the one or more beam sets from the base station; and receiving a downlink control channel from the base station based on the indicated beam set, wherein, if the information indicating any one beam set is not received from the base station, the downlink control channel can be received based on a pre-configured beam set among the beam sets.

    摘要： Disclosed herein are a method and apparatus for performing, by UE, decoding in a wireless communication system. According to the present invention, there may be a method and an apparatus for decoding data in which a demodulation reference signal (DMRS) configured by a base station according to a specific pattern is received from the base station through a DMRS symbol, the demodulation reference signal is transmitted on a specific antenna port and located on the same one or two time-axis symbols as at least one other demodulation reference signal transmitted on another antenna port, the specific pattern is determined according to characteristics of a frequency band in which the demodulation reference signal is transmitted, the demodulation reference signal is mapped to the one or two time-axis symbols using at least one of a first code division multiplexing (CDM) on a frequency axis or a second CDM on a time axis, and the data are decoded using the demodulation reference signal.

    摘要： A method for transmitting a sounding reference signal (SRS) by a by a user equipment (UE) includes: receiving, from a base station, first information on a number of SRS symbols configured for one slot and second information on a number of repetitions of symbols configured for transmission of an SRS; determining whether the number of repetitions is greater than the number of the SRS symbols; when the number of repetitions is greater than the number of the SRS symbols, determining the number of repetitions of the symbols by a value identical to the number of the SRS symbols; and transmitting the SRS based on the determined number of repetitions. 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.
