Abstract: A CSI reporting method by a terminal in a wireless communication system can comprise the steps of: receiving, from a base station, CSI configuration information for CSI reporting; and reporting, to the base station, CSI generated on the basis of the CSI configuration information. If the CSI comprises CQI and defined is a CQI table in which different CQI indexes are allocated by different MCS levels for the CQI reporting, the CSI configuration information comprises a CQI index range reportable by the terminal in the CQI table and/or CQI configuration information relating to the interval between the CQI indexes reportable by the terminal in the CQI index range.

Abstract: Systems and techniques for reporting channel state information (CSI) in a wireless communication system and a device therefor. Particularly, a method for reporting channel state information (CSI) of a terminal in a wireless communication system can include the steps of: measuring a CSI reference signal (CSI-RS) transmitted by means of multi-panels from a base station; and reporting CSI, which is generated on the basis of the CSI-RS measurement, to the base station. If the terminal receives, from the base station, configuration of a CSI report excluding a matrix index for phase calibration between panels, the CSI includes only a first matrix index, for wide-band (WB) panel compensation, and a second matrix index, for subband (SB) panel compensation, and can be calculated by means of the first matrix index, the second matrix index and a particular matrix index associated with the phase calibration between the panels.

Abstract: Provided are a method and equipment for performing device-to-device communication by sharing an uplink resource and a sidelink resource in a wireless communication system. Particularly, a first terminal transmits a reference signal to a base station. The first terminal receives a downlink control signal from the base station. The downlink control signal includes beam limiting information indicating a beam, which is not used for reducing interference with an uplink signal, when the first terminal transmits a sidelink signal. The first terminal transmits the sidelink signal to a second terminal by using beams excluding the beam indicated by the beam limiting information. The sidelink signal is transmitted through a resource pool in which the uplink resource and the sidelink resource are overlapped in time and frequency domains.

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.
