Abstract: Disclosed are a method for transmitting or receiving channel state information in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting channel state information by a terminal in the wireless communication system comprises the steps of: receiving interference measurement restriction information indicating a restriction of interference measurement from a base station; deriving an interference measurement based on a channel state information-interference measurement (CSI-IM) resource in only one first subframe in order to calculate a channel quality indicator (CQI); and reporting the CQI to the base station, wherein the interference restriction information may be independently set for each CSI-IM resource.

Abstract: Disclosed is a method for uplink transmission and reception in a wireless communication system and an apparatus therefor. Specifically, a method for performing uplink transmission by a user equipment (UE) in a wireless communication system may comprise the steps of: receiving downlink control information (DCI) including sounding reference signal (SRS) resource indication (SRI) and precoding indication from a base station; and transmitting an uplink to the base station by applying precoding indicated by the precoding indication on an antenna port of an SRS transmitted within an SRS resource selected by the SRI.
