In an optional scheme, the CSI report configuration information includes implicit or explicit indication information, where the indication information is used to indicate a CSI measurement result type that an associated CSI report should include.

The indication information displayed above may be indicated by using 3 bits, and may of course be other bit numbers, for example:

For example: with regard to the above-mentioned 5 types,

type 1: including 1 RI reported information, such as cri-RI-LI-PMI-CQI;

The foregoing prioritization is exemplified by 5 types, and certainly in practical applications, if there are no 5 types, the prioritization is also performed by a priority corresponding to an existing type, for example, if there is no CSI measurement result of type 2, the prioritization may include: the CSI measurement result of type 4 is more than or equal to the CSI measurement result of type 1 and more than or equal to the CSI measurement result of type 3. If there is no CSI measurement result of type 1, the prioritization may include: the CSI measurement result of the type 2 is more than or equal to the CSI measurement result of the type 4 and more than or equal to the CSI measurement result of the type 3.

The priority may be used when discarding the CSI measurement result, and certainly in practical applications, the condition of discarding the CSI measurement result may also be used in other scenarios, for example, determining a measurement sequence according to the priority, and the like, where the condition of discarding the CSI measurement result may be to discard when the uplink feedback resource is limited, and certainly may also be other conditions, for example, to discard after receiving a discard command of the network device.

Further, when dropping, CSI measurement results of low priority may be dropped preferentially, or CSI measurement results of high priority may be dropped preferentially.
