Abstract: Disclosed herein are a method and a device for transmitting and receiving uplink data in a wireless communication system. According to the present disclosure, a UE may transmit to a base station information related to a capability of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive Downlink Control Information (DCI) for transmitting the uplink data from the base station and the DCI may include a TPMI used for the UE to transmit the uplink data. Thereafter, the UE may transmit to the base station the uplink data by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.

Abstract: Disclosed are a method and a device for dynamically indicating and applying spatial parameters in a wireless communication system. A method for applying spatial parameters by means of a terminal in a wireless communication system, according to one embodiment of the present disclosure, comprises the steps of: receiving, from a base station, downlink control information (DCI) including first information on one or more spatial parameters, second information on time domain resource allocation, and third information on whether to schedule a data channel; transmitting, on the basis of the second information, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information to the base station on the basis of the third information indicating that the data channel is not scheduled; and after transmitting the HARQ-ACK information, performing uplink transmission to the base station or downlink reception from the base station on the basis of the one or more spatial parameters based on the first information.

Abstract: Systems and techniques for transmitting channel state information (CSI) include: receiving configuration information related to the CSI from a base station, the configuration information including information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station based on the configuration information and the CSI-RS. The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (N≤M) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1≤n≤N) CSI set, a specific CSI-RS resource in an n-th (1≤n≤N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.
