Abstract
Embodiments of this application provide a sidelink communication method and device. The method includes: A communication device obtains configuration information and a transmission resource. The configuration information includes configuration of a first resource pool and configuration of a second resource pool. According to the method, it can be ensured that the transmission resources of the first resource pool and the second resource pool are used to send different information.
Claims20
A method, comprising:
- obtaining, by a first communication device, configuration information, wherein the configuration information comprises configuration of a first resource pool and configuration of a second resource pool, the first resource pool is configured to be used to send first information, and the second resource pool is configured to be used to send second information;
- obtaining, by the first communication device, a transmission resource, wherein the transmission resource belongs to the first resource pool or the second resource pool;
- and
- performing a selection by:
- selecting, by the first communication device, a first destination tunnel when the transmission resource belongs to the first resource pool, wherein the first destination tunnel is configured to be used to send the first information to a second communication device, and the first information is configured to be used by the first communication device to discover the second communication device, or to be used for the first communication device to be discovered by the second communication device;
- and
- selecting, by the first communication device, a second destination tunnel when the transmission resource belongs to the second resource pool, wherein the second destination tunnel is configured to be used to send the second information, wherein the second information is used for normal communication, and the normal communication is sidelink communication other than a discovery process.

A method, comprising:
- sending, by a network device, configuration information to a first communication device, wherein the configuration information comprises configuration of a first resource pool and configuration of a second resource pool, the first resource pool is configured to be used for transmission of first information, and the second resource pool is configured to be used for transmission of second information;
- and
- sending, by the network device, a transmission resource to the first communication device, wherein the transmission resource belongs to the first resource pool or the second resource pool, and wherein:
- when the transmission resource belongs to the first resource pool, a first destination tunnel is used by the first communication device to send the first information to a second communication device, wherein the first information is used by the first communication device to discover the second communication device, or is used for the first communication device to be discovered by the second communication device;
- and
- when the transmission resource belongs to the second resource pool, a second destination tunnel is used by the first communication device to send the second information, wherein the second information is used for normal communication, and the normal communication is sidelink communication other than a discovery process.

- obtain a transmission resource, wherein the transmission resource belongs to the first resource pool or the second resource pool;
- and
- perform a selection by:
- select a first destination tunnel when the transmission resource belongs to the first resource pool, wherein the first destination tunnel is configured to be used to send the first information to a second communication device, and the first information is configured to be used to discover the second communication device, or to be used for the apparatus to be discovered by the second communication device;
- and
- select a second destination tunnel when the transmission resource belongs to the second resource pool, wherein the second destination tunnel is configured to be used to send the second information, wherein the second information is configured to be used for normal communication, and the normal communication is sidelink communication other than a discovery process.
