Abstract
This application relates to the field of communication technologies, and discloses a communication method and apparatus. In an implementation, the method includes: a first terminal device determines a first discontinuous reception (DRX) parameter based on a transmission requirement of a first vehicle-to-everything (V2X) service, where the transmission requirement includes a service requirement and/or a message pattern; and the first terminal device sends the first DRX parameter to a second terminal device, where the first DRX parameter is used for proximity communication 5 (PC5) communication of the first V2X service between the first terminal device and the second terminal device
Claims19
A communication method, comprising:
- receiving, by a second terminal device, a first discontinuous reception (DRX) parameter from a first terminal device, wherein the first DRX parameter is used for proximity communication 5 (PC5) communication of a first vehicle to everything (V2X) service between the first terminal device and the second terminal device;
- and
- performing, by the second terminal device, PC5 communication of the first V2X service with the first terminal device based on the first DRX parameter.
A communication apparatus, comprising:
- a memory storing instructions;
- and
- at least one processor in communication with the memory, wherein the at least one processor executes the instructions to:
- receive a first discontinuous reception (DRX) parameter from a first terminal device, wherein the first DRX parameter is used for proximity communication 5 (PC5) communication of a first vehicle to everything (V2X) service between the first terminal device and the communication apparatus;
- and
- perform PC5 communication of the first V2X service with the first terminal device based on the first DRX parameter.
A communication system, comprising:
- a first terminal device and a second terminal device;
- wherein the first terminal device is configured to:
- send, by a vehicle-to-everything (V2X) layer of a first terminal device, a transmission requirement of a first V2X service to an access stratum of the first terminal device;
- determine, by the access stratum of the first terminal device, a first discontinuous reception (DRX) parameter based on a transmission requirement of the first V2X service, wherein the transmission requirement comprises a service requirement;
- and
- send, to a second terminal device, the first DRX parameter for proximity communication 5 (PC5) communication of the first V2X service between the first terminal device and the second terminal device;
- and
- wherein the second terminal device is configured to:
- receive the first DRX parameter from a first terminal device, wherein the first DRX parameter is used for PC5 communication of a first V2X service between the first terminal device and the second terminal device;
- and
- perform PC5 communication of the first V2X service with the first terminal device based on the first DRX parameter.
