Abstract
Embodiments of this application disclose a communication method and device, and relate to the communications field, to efficiently deliver a vehicle-to-everything (V2X) message by using limited bandwidth resources of PC5. The method includes: receiving, by a first node, PC5 broadcast reference information from a second node, where the PC5 broadcast reference information is used to indicate to send target data from the second node in a PC5 interface broadcast mode; and sending, by the first node, the target data in the PC5 interface broadcast mode based on the PC5 broadcast reference information.
Claims17
A communication method, comprising:
- receiving, by a first node, PC5 broadcast reference information from a second node, wherein the PC5 broadcast reference information indicates to send target data from the second node in a PC5 interface broadcast mode;
- and
- sending, by the first node, the target data in the PC5 interface broadcast mode based on the PC5 broadcast reference information,
- wherein the PC5 broadcast reference information comprises a target data filtering rule for filtering data from the second node to obtain the target data;
- and
- the sending, by the first node, the target data in the PC5 interface broadcast mode based on the PC5 broadcast reference information comprises:
- filtering, by the first node, the data from the second node according to the target data filtering rule, to obtain the target data;
- and
- sending, by the first node, the target data in the PC5 interface broadcast mode.
A communication method, comprising:
- obtaining, by a second node, PC5 broadcast reference information, wherein the PC5 broadcast reference information indicates to send target data in a PC5 interface broadcast mode;
- and
- sending, by the second node, the PC5 broadcast reference information to a first node for the first node to send the target data in the PC5 interface broadcast mode based on the PC5 broadcast reference information,
- wherein the PC5 broadcast reference information comprises a target data filtering rule for filtering data from the second node to obtain the target data;
- and
- the sending of the target in the PC5 interface broadcast mode based on the PC5 broadcast reference information comprises:
- filtering the data from the second node according to the target data filtering rule, to obtain the target data;
- and
- sending the target data in the PC5 interface broadcast mode.
A communication system, comprising a first node and a second node, wherein
- the second node is configured to obtain PC5 broadcast reference information, wherein the PC5 broadcast reference information indicates to send target data in a PC5 interface broadcast mode, and send the PC5 broadcast reference information to the first node;
- and
- the first node is configured to receive the PC5 broadcast reference information from the second node, and send the target data in the PC5 interface broadcast mode based on the PC5 broadcast reference information,
- wherein the PC5 broadcast reference information comprises a target data filtering rule for filtering data from the second node to obtain the target data;
- and
- the first node is further configured to filter the data from the second node according to the target data filtering rule to obtain the target data, and send the target data in the PC5 interface broadcast mode.
