Claim 6:
7. The method according to claim 1, further comprising:
receiving, by a transmit end device, 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;
sending, by the transmit end device, the precoded to-be-sent data; and
performing the following:
sending, by the transmit end device, 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
sending, by the transmit end device, 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; and

wherein pre-coding the to-be-sent data based on the matrix P, to generate the precoded to-be-sent data, comprises:
precoding, by the transmit end device, the to-be-sent data based on the receiving capability information and based on the matrix P.
