Classification: CPC H | IPC H

Claim 3:
4. A network apparatus, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the network apparatus to implement operations comprising:
generating transmission parameter indication information indicating an index in an index set of one codebook subset configuration of three codebook subset configurations, wherein the three codebook subset configurations are related to fully coherent, partial coherent, and incoherent respectively, wherein each index in the index set is associated with a quantity of transmission layer and a precoding matrix indicator, and a combination of the quantity of transmission layers and the precoding matrix indicator indicates a respective precoding matrix, and an index set of the codebook subset configuration related to fully coherent includes M first indexes, an index set of the codebook subset configuration related to partial coherent includes N second indexes, and an index set of the codebook subset configuration related to incoherent includes K third indexes, M is an integer larger than N, and N is an integer larger than K, wherein a third index and a second index with a same index value are associated with a same quantity of transport layers and a same precoding matrix indicator, and a second index and a first index with a same index value are associated with a same quantity of transport layers and a same precoding matrix indicator, and at least first 12 third indexes are the same as first 12 second indexes, and at least first 32 second indexes are the same as first 32 first indexes; determine a transmission layer and precoding matrix associated with the index according to the transmission parameter indication information, wherein contents of the three codebook subset configurations are represented by the following table:, Field
