Patent number: 11817929Abstract: 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.
