Abstract
A channel state information measurement method and apparatus and a network side device are described. The measurement method includes configuring, by a network side device, channel state information reference signal (CSI-RS) transmit information of M access points. The CSI-RS transmit information is used to indicate the M access points to periodically send a CSI-RS to a first user equipment at a preset interval. The preset interval is a time interval and/or a subband interval, and M is an integer greater than 1. The network side device obtains channel state information (CSI) corresponding to each of the M access points. The CSI corresponding to the access point includes first CSI, and the first CSI is information that is measured based on the CSI-RS corresponding to the access point and fed back by the first user equipment.
