Information Transmission Method and Device

A sending device, comprising:

• a processor, a memory, and a computer program that is stored in the memory and that can run on the processor, wherein when the computer program is executed by the processor, the processor is configured to implement following step:
• sending first target information on a first target resource of the first sending device;
• wherein
• the first target resource is related to at least one of the following:
• M first modes of the first sending device, N first synchronization sources searched by the first sending device, and indication information;
• and
• the M first modes comprise at least one of the following:
• a second mode supported by the first sending device, and a current third mode of the first sending device, the indication information is used to indicate that the first sending device is within or outside coverage of a first target synchronization source, the first target synchronization source is at least one of the N first synchronization sources, and M and N are positive integers.

A receiving device, comprising:

• a processor, a memory, and a computer program that is stored in the memory and that can run on the processor, wherein when the computer program is executed by the processor, the processor is configured to implement following step:
• receiving first target information from a first sending device on a first target resource;
• wherein
• the first target resource is related to at least one of the following:
• M first modes of the first sending device, N first synchronization sources found by the first sending device, and indication information;
• and
• the M first modes comprise at least one of the following:
• a second mode supported by the first sending device, and a current third mode of the first sending device, the indication information is used to indicate that the first sending device is within or outside coverage of a first target synchronization source, the first target synchronization source is at least one of the N first synchronization sources, and M and N are positive integers.
