在具体实现中，上行反馈资源受限时，为了降低终端设备的反馈开销，终端设备可以选择丢弃CSI报告。当然在其他的条件，终端设备也可以选择丢弃CSI报告，例如，接收到网络设备的丢弃命令后。
其中，当丢弃CSI报告时，可以优先丢弃CSI报告中的部分2或CSI报告中的部分1。例如，当终端设备需要上报CSI测量结果类型相同的CSI报告A和CSI报告B时，终端设 备可以选择先丢弃CSI报告A和CSI报告B中的部分1，再丢弃CSI报告A和CSI报告B中的部分2；或者先丢弃CSI报告A和CSI报告B中的部分2，再丢弃CSI报告A和CSI报告B中的部分1。
进一步地，当CSI测量结果的类型不同时，终端设备可以优先丢弃低优先级的CSI测量结果，或者优先丢弃高优先级的CSI测量结果。优先级顺序为：CSI测量结果为类型1的CSI报告>＝CSI测量结果为类型2的CSI报告，所述CSI报告的优先级Pri iCSI(y,k,c,s)可具体示意为：
Pri iCSI(y,k,c,s)＝2*N cells*M s*y+N cells*M s*k+M s*c+s
其中，对于被调度承载在PUSCH的非周期CSI报告，y的取值为0；对于被调度承载在PUSCH的半持续调度的CSI报告，y的取值为1；对于被调度承载在PUCCH的半持续调度的CSI报告，y的取值为2；对于被调度承载在PUCCH的周期CSI报告，y的取值为3。所述c为小区索引值，N cells是高层参数maxNrofServingCells服务小区数目的取值。所述s是CSI报告配置ID的reportConfigID，M s是高层参数maxNrofCSI-ReportConfigurations CSI报告配置数目的取值。所述k是终端设备测量参数的类型，对于承载L1-RSRP或者L1-SINR的CSI报告，k的取值为0；对于承载非L1-RSRP或者L1-SINR的CSI报告，k的取值为1。如果一个CSI报告A关联的Pri iCSI(y,k,c,s)取值小于一个CSI报告B关联的Pri iCSI(y,k,c,s)的取值，则CSI报告A的优先级高于CSI报告B。
示例性地，当终端设备需要上报CSI测量结果类型为类型2的CSI报告和CSI测量结果为类型1的CSI报告时，终端设备可以选择先丢弃CSI测量结果类型为类型1的CSI报告中的部分2；若上行反馈资源还是不足，终端设备可以再丢弃CSI测量结果类型为类型2的CSI报告中的部分2；若上行反馈资源还是不足，再丢弃CSI测量结果类型为类型1的CSI报告中的部分1；若上行反馈资源还是不足，最后再丢弃CSI测量结果类型为类型2的CSI报告中的部分1。
示例性地，当终端设备需要上报CSI测量结果类型为类型2的CSI报告和CSI测量结果为类型1的CSI报告时，终端设备可以选择先丢弃CSI测量结果类型为类型2的CSI报告中的部分1；若上行反馈资源还是不足，终端设备可以再丢弃CSI测量结果类型为类型1的CSI报告中的部分1；若上行反馈资源还是不足，再丢弃CSI测量结果类型为类型2的CSI报告中的部分2；若上行反馈资源还是不足，最后再丢弃CSI测量结果类型为类型1的CSI报告中的部分2。
需要说明的是，上述优先级可以用于丢弃CSI报告中的组时使用，当然在实际应用中，还可以采用在其他场景，例如依据优先级确定测量顺序等等。
S230、终端设备向网络设备上报CSI报告。
具体地，终端设备获取到CSI报告后，将该CSI报告上报给网络设备。
S240、网络设备接收来自终端设备的CSI报告。
相应地，网络设备接收到终端设备发送的CSI报告，再利用压缩模型，对压缩后的信道信息进行恢复。通过这种方式，既可有效地降低终端反馈开销，同时与现有CSI反馈机制相比，网络设备又可以获取高精度地信道信息。
