The present disclosure discloses a method of receiving channel state information (CSI) and an access network device, so as to resolve a technical problem that timely scheduling cannot be implemented due to a relatively long time required for transmitting CSI in a D-RAN architecture. The method includes: receiving, by a first access network device, a notification message sent by a second access network device, where the notification message is used to indicate condition information based on which a terminal device camping on a first cell of the second access network device sends CSI; and receiving, by the first access network device, on a resource determined according to the condition information indicated by the notification message, the CSI sent by the terminal device.
