Disclosed are a method for transmitting/receiving channel state information in a wireless communication system and a device for same. In particular, a method of reporting channel state information (CSI), by a user equipment (UE) in a wireless communication system comprises the steps of: receiving, from an eNB, a CSI process configuration comprising interference measurement restriction information indicating interference measurement restriction; and reporting, to the eNB, CSI corresponding to a CSI process configured by the CSI process configuration, wherein when a first subframe set and a second subframe set are configured for the CSI process, the interference measurement restriction can be independently configured for each of the first subframe set and the second subframe set.
