CSI-RS Measurement Method and Indication Method, Network Device, And Terminal

A terminal, comprising:

• a transceiver, the transceiver configured to receive, from a network device, a partial channel state information reference signal resource sets selected from a plurality of channel state information reference signal resource sets, and indication information indicating one or more resource sets for channel measurement, wherein the one or more resource sets for channel measurement are from the partial channel state information reference signal resource sets;
• and
• at least one processor, the at least one processor configured to perform channel measurement by using the one of the one or more resource sets for channel measurement indicated by the indication information.

A method for indicating a channel state information reference signal resource, comprising:

• sending, by a network device, a partial channel state information reference signal resource sets selected from a plurality of channel state information reference signal resource sets to a terminal;
• and
• sending, by the network device, indication information indicating one or more resource sets for channel measurement, wherein the one or more resource sets for channel measurement are from the partial channel state information reference signal resource sets.

A network device, comprising:

• at least one processor, the at least one configured to select a partial channel state information reference signal resource sets from a plurality of channel state information reference signal resource sets;
• and
• a transceiver, the transceiver configured to send the partial channel state information reference signal resource sets and indication information indicating one or more resource sets for channel measurement to a terminal, wherein the one or more resource sets for channel measurement are from the partial channel state information reference signal resource sets.
