METHOD FOR ADJUSTING PARAMETERS OF SENDING DEVICE AND RECEIVING DEVICE, AND TERMINAL DEVICE

摘要

The present invention discloses a method for adjusting parameters of a sending device and a receiving device, and a terminal device. In the method, a new precoding parameter that needs to be used by a sending device on a line when a precoding matrix in a downlink direction of the line changes, and a new signal recovery parameter that needs to be used by a receiving device and matches the new precoding parameter are first acquired; and then the new precoding parameter, the new signal recovery parameter, and a set moment and/or symbol at which the sending device starts to use the new precoding parameter are sent to the sending device, and the new signal recovery parameter and the set moment and/or symbol are sent to the receiving device by using the sending device.

1. A method for adjusting parameters of a sending device and a receiving device of a line, comprising:
acquiring, by a terminal device, a new precoding parameter that needs to be used by the sending device on the line when a precoding matrix in a downlink direction of the line changes, wherein the new precoding parameter comprises at least a new precoding matrix for performing precoding processing on a signal to be sent though the line; acquiring a new signal recovery parameter that needs to be used by the receiving device on the line and matches the new precoding parameter; and sending, to the sending device, the new precoding parameter, the new signal recovery parameter, and a set moment and/or symbol at which the sending device starts to use the new precoding parameter to enable the sending device to send the new signal recovery parameter and the set moment and/or symbol to the receiving device, so that at the set moment and/or symbol, the sending device starts to use the new precoding parameter and the receiving device starts to use the new signal recovery parameter that matches the new precoding parameter.
