Measurement method, and apparatus

A measurement method, comprising:

• receiving, by a second network device, a restricted CSI measurement instruction sent by a first network device, wherein the restricted CSI measurement instruction is used to instruct the second network device to perform restricted CSI measurement;
• performing, by the second network device, restricted CSI measurement based on the restricted CSI measurement instruction;
• and
• sending, by the second network device, CSI to the first network device, wherein the CSI is generated after the second network device completes the CSI measurement based on the CSI measurement instruction.

A network device, comprising:

• a transmitter, configured to send a restricted channel state information (CSI) measurement instruction to user equipment, and the restricted CSI measurement instruction is used to instruct the second network device to perform restricted CSI measurement;
• a processor, configured to instruct the transmitter to send the restricted CSI measurement instruction;
• and
• a receiver, configured to receive CSI sent by the user equipment, and the CSI is generated after the CSI measurement is completed based on the CSI measurement instruction.

User apparatus, comprising:

• a receiver, configured to receive a restricted CSI measurement instruction sent by a network device, and the restricted CSI measurement instruction is used to instruct the user equipment to perform restricted CSI measurement;
• a processor, configured to perform restricted CSI measurement based on the restricted CSI measurement instruction;
• and
• a transmitter, configured to send CSI to the network device, wherein the CSI is generated after the user equipment completes the CSI measurement based on the CSI measurement instruction.
