Abstract: This application provides a dynamic time assignment method, apparatus, and system, and relates to the field of communications technologies. The method includes: Central office equipment and customer premise equipment obtain a length of a new downstream transmission duration. The central office equipment and the customer premise equipment first shorten a downstream transmission duration or an upstream transmission duration whose length needs to be shortened; and after lengths of all downstream transmission durations or all upstream transmission durations are shortened, prolong the length of the downstream transmission duration or the upstream transmission duration whose length needs to be prolonged.

Abstract: The present disclosure provides a data transmission method including: receiving a first-mode optical signal from a first port corresponding to a first port number; converting, according to a correspondence between the first port number and a first mode group number, the received first-mode optical signal into a second-mode optical signal carried in a first mode group identified by the first mode group number, where the second-mode optical signal carried in the first mode group identified by the first mode group number includes an optical signal in one or more modes; and outputting the second-mode optical signal obtained by means of conversion.

Abstract: 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.
