Sidelink resource recommendation method and apparatus, device, and readable storage medium

A first terminal, comprising:

• a memory storing computer-readable instructions;
• and
• a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:
• performing a first operation, wherein the first operation comprises one or more of the following:
• sending first information to a second terminal, wherein the first information is used to trigger the second terminal to recommend a first resource to the first terminal;
• or
• receiving second information from the second terminal, wherein the second information comprises information about the first resource;
• based on whether the first terminal supports a capability of carrier sensing, determining, by the first terminal, a target resource comprising at least one of the first resource or a second resource, wherein the second resource is a resource autonomously selected by the first terminal;
• and
• transmitting, by the first terminal, a first Transport Block (TB) to be transmitted through the target resource,
• wherein sending, by the first terminal, the first information to the second terminal comprises:
• sending, by the first terminal, the first information to the second terminal by using a third resource,
• wherein the SL resource recommendation method further comprises:
• triggering, by the first terminal, selection for the third resource and selection for the transmission resource independently,
• wherein when the selection for the transmission resource and the selection for the third resource are independently triggered, trigger of the selection for the transmission resource is related to the first information or the second information, and
• wherein that trigger of the selection for the transmission resource is related to the first information or the second information comprises one or more of the following:
• after the selection for the third resource is triggered, when the first terminal does not send or fails to send the first information within a first preset time, triggering, by the first terminal, the selection for the transmission resource;
• after the selection for the third resource is triggered, when the first terminal fails to receive or fails to demodulate the second information within a second preset time, triggering, by the first terminal, the selection for the transmission resource;
• or
• after the first information is sent, when the first terminal fails to receive or fails to demodulate the second information within the second preset time, triggering, by the first terminal, the selection for the transmission resource.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• performing, by a first terminal, a first operation, wherein the first operation comprises one or more of the following:
• sending first information to a second terminal, wherein the first information is used to trigger the second terminal to recommend a first resource to the first terminal;
• or
• receiving second information from the second terminal, wherein the second information comprises information about the first resource;
• based on whether the first terminal supports a capability of carrier sensing, determining, by the first terminal, a target resource comprising at least one of the first resource or a second resource, wherein the second resource is a resource autonomously selected by the first terminal;
• and
• transmitting, by the first terminal, a first Transport Block (TB) to be transmitted through the target resource,
• wherein sending, by the first terminal, the first information to the second terminal comprises:
• sending, by the first terminal, the first information to the second terminal by using a third resource,
• wherein the SL resource recommendation method further comprises:
• triggering, by the first terminal, selection for the third resource and selection for the transmission resource independently,
• wherein when the selection for the transmission resource and the selection for the third resource are independently triggered, trigger of the selection for the transmission resource is related to the first information or the second information, and
• wherein that trigger of the selection for the transmission resource is related to the first information or the second information comprises one or more of the following:
• after the selection for the third resource is triggered, when the first terminal does not send or fails to send the first information within a first preset time, triggering, by the first terminal, the selection for the transmission resource;
• after the selection for the third resource is triggered, when the first terminal fails to receive or fails to demodulate the second information within a second preset time, triggering, by the first terminal, the selection for the transmission resource;
• or
• after the first information is sent, when the first terminal fails to receive or fails to demodulate the second information within the second preset time, triggering, by the first terminal, the selection for the transmission resource.
