Data transmission method and apparatus

A transmit device, comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory, the processor configured to execute the instructions stored in the memory to cause the transmit device to perform operations comprising:
• generating a first data frame sequence, wherein the first data frame sequence comprises a first data frame, the first data frame comprises a switching interval, the switching interval comprises first identification information, and the first data frame corresponds to a first data period;
• detecting whether a beam adjustment request is received within the first data period, and if the beam adjustment request is received, setting the first identification information in the switching interval of the first data frame to invalid, including, filling invalid data in a first payload area of the first data frame, and performing beam adjustment within the first data period;
• or if no beam adjustment request is received within the first data period, setting the first identification information to valid, including, filling valid data in the first payload area of the first data frame, wherein the switching interval comprises a first interval header and the first payload area, and the first identification information is located in the first interval header and is used to indicate validity of data in the first payload area of the switching interval in which the first identification information is located;
• and
• sending the first data frame.

A non-transitory computer storage medium having instructions stored therein, which when executed by one or more processors, cause the one or more processors to perform operations, the operations comprising:

• generating a first data frame sequence, wherein the first data frame sequence comprises a first data frame, the first data frame comprises a switching interval, the switching interval comprises first identification information, and the first data frame corresponds to a first data period;
• detecting whether a beam adjustment request is received within the first data period, and if the beam adjustment request is received, setting the first identification information in the switching interval of the first data frame to invalid, including, filling invalid data in a first payload area of the first data frame, and performing beam adjustment within the first data period;
• or if no beam adjustment request is received within the first data period, setting the first identification information to valid, including, filling valid data in the first payload area of the first data frame, wherein the switching interval comprises a first interval header and the first payload area, and the first identification information is located in the first interval header and is used to indicate validity of data in the first payload area of the switching interval in which the first identification information is located;
• and
• causing a first transmit device to send the first data frame.
