    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： 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： According to one embodiment of the present specification, a method for determining a beam to be used by a terminal for communication in an mmWave communication system can be provided. Here, the method for determining a beam to be used by a terminal for communication may comprise the steps of: receiving a CSI-RS from a base station; reporting a preferred primary beam to the base station on the basis of the received CSI-RS; receiving secondary beam information from the base station on the basis of the preferred primary beam; reporting a preferred secondary beam from among the secondary beam information to the base station; and receiving a setting of a CSI-RS resource from the base station on the basis of the preferred secondary beam. Here, the secondary beam information may include the preferred primary beam and at least one secondary beam to which QCL is applied.

    摘要： Performing uplink reception by a base station (BS) in a wireless communication system. In some implementations, a method includes: transmitting configuration information for a first sounding reference signal (SRS) that specifies a relation between the first SRS and a second SRS that is a reference for spatial beamforming of the first SRS, and based on the configuration information, receiving the first SRS which is transmitted by applying, to the first SRS, a first spatial beamforming that is identical to a second spatial beamforming used for transmission of the second SRS. The method further includes transmitting downlink control information (DCI) for uplink scheduling, where the DCI includes a SRS resource indication (SRI) and where a SRI field in the DCI carries the SRI, and where a bit width of the SRI field is based on a number of SRS resources in an SRS resource set configured for a user equipment (UE).
