Resource sharing method and apparatus, and terminal device

1. A resource sharing method, comprising:

receiving, by a first terminal device, first configuration information transmitted by a network device, the first configuration information being used to configure one or more first sidelink transmission resources; and

transmitting, by the first terminal device, resource reservation indication information on a sidelink, the resource reservation indication information being used to indicate that the one or more first sidelink transmission resources are reserved by the first terminal device, and

the method further comprising:

obtaining, by the first terminal device, a fourth sidelink transmission resource in response to detecting that the one or more first sidelink transmission resources are occupied or reserved by a second terminal device, and transmitting the resource reservation indication information on the fourth sidelink transmission resource,

wherein said obtaining, by the first terminal device, the fourth sidelink transmission resource comprises:

obtaining, by the first terminal device, resource pool configuration information, and determining a second resource pool based on the resource pool configuration information; and

determining, by the first terminal device, the fourth sidelink transmission resource from the second resource pool by means of sensing or random selection.

2. The method according to claim 1 , wherein the resource reservation indication information is carried in Sidelink Control Information (SCI).

3. The method according to claim 2 , wherein the SCI further carries at least one of:

fifth indication information used to indicate that the one or more first sidelink transmission resources are allocated by the network device or that the first terminal device is operating in a first mode; wherein the first terminal device uses one or more sidelink transmission resources allocated by the network device when operating in the first mode;

sixth indication information used to determine a time interval between the one or more reserved first sidelink transmission resources and a transmission resource for transmitting the resource reservation indication information; and

seventh indication information used to determine a number of times the one or more first sidelink transmission resources are reserved.

4. The method according to claim 1 , further comprising:

receiving, by the first terminal device, third configuration information or first control information transmitted by the network device, the third configuration information being used to configure a third sidelink transmission resource, the first control information being used to indicate release of the one or more first sidelink transmission resources; and

transmitting, by the first terminal device, ninth indication information used to indicate that no resource is reserved by the first terminal device.

5. A terminal device, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and execute the computer program stored in the memory to perform the method according to claim 1 .

6. A chip, comprising a processor configured to invoke and execute a computer program from a memory, to cause an apparatus provided with the chip to perform the method according to claim 1 .

7. A non-transitory computer-readable storage medium, configured to store a computer program that causes a computer to perform the method according to claim 1 .
