Classification: CPC H | IPC H

Claim 16:
17. A communications chip comprising at least one processor, wherein the at least one processor is coupled with at least one memory that stores computer instructions, that when executed by the at least one processor, cause the communications chip to perform at least following operations:
receiving indication information for indicating M N-dimensional precoding vectors,
wherein each precoding vector is applied to one of M frequency bands,
wherein the M N-dimensional precoding vectors form a space-frequency matrix,
wherein the space-frequency matrix is generated by performing a weighted combination on a plurality of space-frequency component matrices,
wherein the space-frequency matrix is an X×Y space-frequency matrix, X and Y are one and the other of M and N, M≥1, N≥2, and both M and N are integers,
wherein the space-frequency matrix is associated with one spatial stream,
wherein quantities of frequency-domain component vectors associated with each of space-frequency matrices of different spatial streams are the same, and
wherein a larger quantity of spatial streams is associated with a smaller quantity of frequency-domain component vectors; and

determining the M N-dimensional precoding vectors based on the indication information.
