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

Claim 17:
18. A transmit end device, comprising:
a non-transitory memory storing instructions; and
a processor coupled to the memory to, wherein execution of the instructions by the processor causes the transmit end device to:
receive receiving capability information from a receive end device, wherein the receiving capability information indicates that the receive end device supports a non-linear receiving algorithm;
decompose a channel matrix into a product of a matrix Q, a matrix R, and a matrix PH, wherein the matrix PH is a conjugate transpose matrix of a matrix P, both the matrix Q and the matrix P are unitary matrices, and the matrix R is an upper triangular matrix, and wherein a ratio of at least two diagonal elements of the matrix R is a target ratio, and the target ratio is determined based on a code rate;
precode to-be-sent data based on the matrix P and based on the receiving capability information, to generate precoded to-be-sent data;
send the precoded to-be-sent data; and
perform the following:
send indication information to the receive end device, wherein the indication information indicates that the transmit end device precodes the to-be-sent data based on the matrix P; or
send indication information to the receive end device, wherein the indication information indicates to the receive end device to receive the to-be-sent data using the non-linear receiving algorithm.
