Information indication method, network device, and terminal device

An information receiving method, comprising:

• receiving, by a terminal device, control information sent by a network device, wherein the control information is received by way of a channel state information management setting, and the control information comprises first indication information, second indication information, and third indication information, wherein
• the first indication information is used to indicate a plurality of channel state information-reference signal (CSI-RS) resources,
• the second indication information is used to indicate at least one piece of the following information:
• beam index information of the plurality of CSI-RS resources that is sent by the network device, beam index information of the plurality of CSI-RS resources that is received by the terminal device, or beam pair information corresponding to the network device and the terminal, and
• the third indication information is used to indicate a measurement method of the plurality of CSI-RS resources;
• and
• performing, by the terminal device, channel measurement on the plurality of CSI-RS resources based on the control information.

A terminal device, comprising:

• a transceiver, configured to receive control information sent by a network device, wherein the control information is received by way of a channel state information management setting, and the control information comprises first indication information, second indication information, and third indication information, wherein
• the first indication information is used to indicate a plurality of channel state information-reference signal (CSI-RS) resources,
• the second indication information is used to indicate at least one piece of the information:
• beam index information of the plurality of CSI-RS resources that is sent by the network device, beam index information of the plurality of CSI-RS resources that is received by the terminal device, or beam pair information corresponding to the network device and the terminal, and
• the third indication information is used to indicate a measurement method of the plurality of CSI-RS resources;
• and
• a processor, configured to perform channel measurement on the plurality of CSI-RS resources based on the control information.
