Abstract
The present invention discloses a data transmission method, user equipment, and a network device. A D2D communications system configures a logical channel used by different types of D2D data and configures a resource selection parameter for user equipment. In this way, the user equipment is capable of selecting a communication resource by itself according to the resource selection parameter and D2D data to be transmitted by the user equipment, and allocating the resource to the to-be-transmitted D2D data, improving system reliability.
Claims14
A data transmission method, comprising:
- determining, by a terminal, a logical channel used by to-be-transmitted device-to-device (D2D) data;
- determining, by the terminal, a resource selection parameter of the to-be-transmitted D2D data, wherein the resource selection parameter specifies a probability that a resource block in D2D communication resource can be occupied when the to-be-transmitted D2D data is sent;
- selecting, by the terminal according to the resource selection parameter, a D2D communication resource from a configured D2D communication resource;
- and
- sending, on the selected D2D communication resource, the to-be-transmitted D2D data to another terminal by using the determined logical channel.
A data transmission method, wherein the method comprises:
- configuring, by a network device according to a type of to-be-transmitted a device-to-device (D2D) by a terminal, a resource selection parameter that corresponds to D2D data, wherein the resource selection parameter specifies a probability that a resource block in D2D communication resource can be occupied when to-be-transmitted D2D data is sent;
- and
- sending, by the network device, the configured resource selection parameter to the terminal.
A data transmission apparatus, comprising:
- a storage medium including executable instructions;
- and
- a processor;
- wherein the executable instructions, when executed by the processor, cause the apparatus to:
- determine a logical channel used by to-be-transmitted device-to-device (D2D) data and a resource selection parameter of the to-be-transmitted D2D data, wherein the resource selection parameter specifies a probability that a resource block in D2D communication resource can be occupied when the to-be-transmitted D2D data is sent;
- select, according to the resource selection parameter, a D2D communication resource from a configured D2D communication resource;
- and
- send, on the D2D communication resource, the to-be-transmitted D2D data to another terminal by using the determined logical channel.
A data transmission apparatus, comprising:
- a storage medium including executable instructions;
- and
- a processor;
- wherein the executable instructions, when executed by the processor, cause the apparatus to:
- configure, according to a type of to-be-transmitted device-to-device (D2D) data by a terminal, a resource selection parameter that corresponds to the D2D data, wherein the resource selection parameter specifies a probability that a resource block in D2D communication resource can be occupied when the to-be-transmitted D2D data is sent;
- and
- send the resource selection parameter to the terminal.
