Method, Apparatus, Terminal Device, and System for Adjusting Working Status of Aggregated Link

An apparatus for adjusting a working status of an aggregated link, wherein the apparatus comprises:

• a processor;
• and
• a transmitter coupled to the processor, wherein the processor is configured to:
• determine to switch a modulation mode of a first sub-link of the aggregated link from a first modulation mode to a second modulation mode;
• determine a first transmission delay of transmitting a data slice in the second modulation mode by using the first sub-link;
• and
• compare the first transmission delay with a second transmission delay of transmitting a data slice by using another sub-link of the aggregated link, wherein the another sub-link comprises a sub-link that is currently in an enabled state in the aggregated link,
• wherein the transmitter is configured to:
• send information for controlling a working status of the first sub-link to a transmit end device when a difference between the first transmission delay and the second transmission delay meets a preset condition.
