Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A communication method, comprising:
receiving, by a network device, antenna configuration information from a terminal device, wherein the antenna configuration information comprises an antenna parameter for determining a precoding matrix;
measuring, by the network device, a reference signal from the terminal device, to obtain a channel measurement result; and
determining, by the network device, the precoding matrix based on the channel measurement result and the antenna configuration information, and sending first information to the terminal device, wherein the first information indicates the precoding matrix, wherein
the precoding matrix is further determined based on a first matrix and a second matrix; and
at least one of:
the first matrix is determined from a first matrix set based on the channel measurement result, wherein the first matrix set is determined based on a horizontal-dimension parameter of an antenna of the terminal device; or
the second matrix is determined from a second matrix set based on the channel measurement result, wherein the second matrix set is determined based on a vertical-dimension parameter of the antenna.
