Resource sharing method and apparatus

A first apparatus, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and having program instructions stored thereon which, when executed by the at least one processor, cause the apparatus to:
• send first indication information to a second apparatus, wherein the first indication information is to indicate a frequency domain resource of a first initial bandwidth part BWP, wherein the frequency domain resource of the first initial BWP is not shared between the first apparatus and the second apparatus, but is a part of a first candidate shared resource of the first apparatus and the second apparatus;
• receive second indication information from the second apparatus, wherein the second indication information is to indicate a frequency domain resource of a second initial BWP, wherein the frequency domain resource of the second initial BWP is not shared between the second apparatus and the first apparatus, but is a part of the first candidate shared resource;
• send third indication information to the second apparatus, wherein the third indication information is to indicate a time-frequency resource that is in the first candidate shared resource and that is expected by the first apparatus to be used for data transmission;
• and
• receive fourth indication information from the second apparatus, wherein the fourth indication information is to indicate a time-frequency resource that is in the first candidate shared resource and that is expected by the second apparatus to be used for data transmission.

A non-transitory computer-readable storage medium storing programming instructions for execution by at least one processor, wherein the programming instructions, when executed, cause the at least one processor to:

• send first indication information to a second apparatus, wherein the first indication information is to indicate a frequency domain resource of a first initial bandwidth part (BWP), wherein the frequency domain resource of the first initial BWP is not shared between the first apparatus and the second apparatus, but is a part of a first candidate shared resource of the first apparatus and the second apparatus;
• receive second indication information from the second apparatus, wherein the second indication information is to indicate a frequency domain resource of a second initial BWP, wherein the frequency domain resource of the second initial BWP is not shared between the second apparatus and the first apparatus, but is a part of the first candidate shared resource;
• send third indication information to the second apparatus, wherein the third indication information is to indicate a time-frequency resource that is in the first candidate shared resource and that is expected by the first apparatus to be used for data transmission;
• and
• receive fourth indication information from the second apparatus, wherein the fourth indication information is to indicate a time-frequency resource that is in the first candidate shared resource and that is expected by the second apparatus to be used for data transmission.
