Device orientation adjustment method and terminal device

A first terminal device comprising:

• a memory;
• and
• a processor configured to execute a computer program stored in the memory, the computer program comprising instructions for:
• performing communication by using a first optimal receive beam of the first terminal device at a first location and an optimal transmit beam of a network device;
• when a signal quality of the first optimal receive beam and the optimal transmit beam does not meet a preset condition, determining angle information obtained based on a reference direction and a first direction, wherein the reference direction is a direction of the first optimal receive beam obtained when the first terminal device is at the first location, wherein the first direction is a direction of a target receive beam obtained when the first terminal device is at the first location, wherein a signal strength of the target receive beam in free space is greater than signal strength of the first optimal receive beam in the free space, and wherein the angle information is used to indicate at least one rotation angle and a rotation direction corresponding to each rotation angle;
• and
• outputting orientation adjustment indication information based on the angle information or adjusting the first terminal device from the first location to a second location based on the angle information, wherein the orientation adjustment indication information is used to indicate a rotation operation for the first terminal device so that the first terminal device is adjustable from the first location to the second location, and wherein a second optimal receive beam used by the first terminal device to perform the communication with the optimal transmit beam at the second location is the target receive beam.
