1. A method comprising:
receiving, by a terminal of a multiple-input multiple-output (MIMO) system, a downlink signal from a network device of the MIMO system based on a first transport layer quantity;
recognizing, by the terminal, a first scenario and sending a first message to the network device, wherein the first message is to request the network device to reduce a quantity of transport layers used in a downlink data transmission process, wherein the first message carries a second transport layer quantity, wherein the second transport layer quantity is less than the first transport layer quantity, wherein the first scenario comprises one or more of the terminal running a first application in a foreground of the terminal, a data transmission rate of the terminal being less than a first threshold, a strength of a signal from the network device and received by the terminal being greater than a second threshold;
receiving, by the terminal, a second message from the network device, wherein the second message is to configure a quantity of transport layers in the downlink data transmission process, wherein the second message carries a third transport layer quantity, and wherein the third transport layer quantity is less than or equal to the second transport layer quantity; and
receiving and parsing, by the terminal, a downlink signal from the network device based on the third transport layer quantity.
