Frame structure indication method, frame structure updating method, and related device

A method for updating a frame structure, performed by a second device, comprising:

• receiving indication information sent by a first device, wherein the indication information comprises a scaling factor and a preset reference frame used to indicate a first frame structure;
• and
• updating a second frame structure corresponding to the second device with the first frame structure, wherein
• the first frame structure is determined based on user data to be transmitted.

A communications device, wherein the communications device is a first device, comprising:

• a memory storing a computer program;
• and
• a processor coupled to the memory and configured to execute the computer program to perform operations comprising:
• determining a first frame structure based on user data to be transmitted;
• and
• when the first frame structure is different from a second frame structure corresponding to a second device, sending indication information, wherein the indication information comprises a scaling factor and a preset reference frame used to indicate the first frame structure.
