Claim 8:
9. A channel estimation method applied to a channel estimation apparatus including at least one processor, the method comprising:
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.
