Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.

Abstract: The present invention relates to a method whereby user equipment (UE) transmits channel state information (CSI) in a wireless communication system and to a device therefor. According to the present invention, a terminal receives configuration information for CSI reporting from a base station and receives a reference signal from the base station on the basis of the configuration information. The terminal may receive downlink control information (DCI) via a physical downlink control channel (PDCCH), calculate CSI about a particular channel on the basis of the configuration information and the DCI, and report same to the base station.

Abstract: Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.
