    Abstract: The present specification provides a method for transmitting a sounding reference signal (SRS) in a wireless communication system. More particularly, a method for transmitting, by a terminal, a sounding reference signal (SRS) in a wireless communication system comprises: receiving, from a base station, information relating to a plurality of SRS resource sets, the SRS resource sets each comprising one or more SRS resources; and transmitting, to the base station, an SRS on the plurality of SRS resources based on the information, wherein, if the plurality of SRS resources are included in difference SRS resource sets, the SRS is transmitted simultaneously on the plurality of SRS resources.

    Abstract: A method for transmitting a physical uplink shred channel (PUSCH) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH); and transmitting the physical uplink shared channel (PUSCH) on the basis of the DCI. The format of the DCI is DCI format 0_0. On the basis that spatial relation RS information for transmission of the physical uplink shared channel (PUSCH) is not configured, the physical uplink shared channel (PUSCH) is transmitted on the basis of spatial relation quasi-colocation (QCL) RS information of a predefined control resource set (CORESET).

    Abstract: The present invention provides a method for transmitting or receiving a sounding reference signal in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting a sounding reference signal (SRS) by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, configuration information for transmission of the SRS, wherein the configuration information includes one or more SRS resources for transmission of the SRS, a cyclic shift (CS) hopping pattern for the SRS, and CS relation information about whether CS hopping patterns of the SRS and a PUCCH are related; and transmitting the SRS to the base station, through at least one SRS resource among the one or more SRS resources, wherein a CS value applied to the SRS is configured on the basis of the CS hopping pattern for the SRS and the CS relation information.

    Abstract: Disclosed are a codebook-based signal transmission and reception method in a multi-antenna wireless communication system and an apparatus therefor. Specifically, a method for transmitting or receiving a signal on the basis of a codebook by a terminal in a 2-dimensional multi-antenna wireless communication system comprises the steps of: receiving a channel state information reference signal (CSI-RS) through a multi-antenna port from a base station; and reporting channel state information to the base station, wherein the channel state information may include a precoding matrix indicator (PMI) for indicating a precoding matrix, the PMI may include a first PMI for selecting a set of precoding matrixes from the codebook and a second PMI for selecting one precoding matrix from the set of precoding matrixes.

    Abstract: A method by which a base station transmits a signal on the basis of an antenna array in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: determining a multi-rank beam in consideration of (i) positions of a plurality of terminals and (ii) positions of null points of a beam generated through the antenna array; and transmitting signals to the plurality of terminals by using the multi-rank beam. The antenna array may be based on a three-dimensional shape having omnidirectional symmetry, and the positions of the null points and the positions of the plurality of terminals may be configured on the basis of a polar coordinate system using the center of the antenna array as an origin point.
