Abstract

The embodiments of the application provide a communication method, terminal equipment, and network equipment. The method comprises: determining a first data transmission format used to generate first transmission version of uplink data; selecting, from a data resource pool, a first data transmission resource used to transmit the first transmission version; transmitting, to network equipment, a first scheduling configuration message containing information of the first data transmission resource and the first data transmission format; encoding and modulating, according to the first data transmission format, the uplink data, to generate the first transmission version; and transmitting, to the network equipment, by means of the first data transmission resource, the first transmission version, so as to facilitate the network equipment to receive, demodulate and decode, according to the first scheduling configuration message, the first transmission version. The embodiments of the invention can reduce communication latency without decreasing communication reliability.

First claim

The invention claimed is:

1. A communication method, comprising:
determining a first data transmission format, the first data transmission format being used in generating a first transmission version of uplink (UL) data;
selecting a first data transmission resource from a data resource pool, the first data transmission resource being configured to transmit the first transmission version;
sending a first scheduling assignment message to network equipment, the first scheduling assignment message containing information of the first data transmission resource and information of the first data transmission format;
coding the UL data according to the first data transmission format and modulating the coded UL data to generate the first transmission version, and
sending the first transmission version to the network equipment through the first data transmission resource;
responsive to reception of a Non-Acknowledge (NACK) message sent by the network equipment for the first transmission version of the UL data, determining a third data transmission format and selecting a third data transmission resource from the data resource pool, the third data transmission format being used in generating a third transmission version of the UL data and the third data transmission resource being configured to transmit the third transmission version;
sending a second scheduling assignment message to the network equipment, the second scheduling assignment message containing information of the third data transmission resource and information of the third data transmission format;
coding and modulating the UL data according to the third data transmission format to generate the third transmission version; and
sending the third transmission version to the network equipment through the third data transmission resource to enable the network equipment to receive, demodulate and decode the third transmission version according to the second scheduling assignment message.

2. The method as claimed in claim 1 , wherein sending the first transmission version to the network equipment through the first data transmission resource is configured for the network equipment to demodulate and decode the first transmission version according to the first scheduling assignment message.

3. The method as claimed in any one of claim 1 , wherein sending the first scheduling assignment message to the network equipment comprises:
sending the first scheduling assignment message to the network equipment through a transmission resource which is configured by the network equipment for the first scheduling assignment message; or
selecting a control transmission resource from a control resource pool, and sending the first scheduling assignment message to the network equipment through the control transmission resource.

4. The method as claimed in claim 3 , wherein before selecting the first data transmission resource from the data resource pool, the method further comprises:
receiving resource pool configuration information sent by the network equipment, the resource pool configuration information comprising configuration information of the data resource pool and configuration information of the control resource pool, wherein the data resource pool comprises the UL resource that is selectable for transmitting the first transmission version, and the control resource pool comprises a UL resource that is selectable for transmitting the scheduling assignment message.

5. The method as claimed in claim 1 , wherein the method further comprises:
obtaining, ACK message for indicating success of demodulating and decoding the transmission version of the UL data; and
obtaining, NACK message for indicating failure of demodulating and decoding the transmission version of the UL data.

6. The method as claimed in claim 1 , wherein the data transmission format comprises a coded version.

7. A communication method, performed by network equipment, comprising:
receiving a scheduling assignment message sent by terminal equipment, the scheduling assignment message indicating a first data transmission format and first data transmission resource corresponding to a first transmission version of uplink (UL) data sent by the terminal equipment; and
receiving first transmission version sent by terminal equipment through the first data transmission resource;
demodulating the first transmission version of the UL data and decoding the demodulated first transmission version of the UL data according to the first data transmission format and the first data transmission resource,
wherein receiving the scheduling assignment message sent by the terminal equipment comprises:
performing blind detection on the scheduling assignment message sent by the terminal equipment through a resource indicated by the control resource pool; or
receiving the scheduling assignment message sent by the terminal equipment through a control resource configured for the scheduling assignment message of the terminal equipment.

8. The method as claimed in claim 7 , before receiving the scheduling assignment message sent by the terminal equipment, further comprising:
configuring a data resource pool to the terminal equipment, the data resource pool comprising a UL resource that is selectable by the terminal equipment for transmitting the first transmission version; and
configuring a control resource pool for the terminal equipment, the control resource pool comprising a UL resource that is selectable by the terminal equipment for transmitting the scheduling assignment message, or configuring the UL resource for the terminal equipment to transmit the scheduling assignment message.

9. The method as claimed in claim 7 , further comprising:
sending an Acknowledge (ACK) message for indicating success of demodulating and decoding the transmission version of the UL data.

10. The method as claimed in claim 7 , further comprising:
sending an Non-Acknowledge (NACK) message for indicating failure of demodulating and decoding the transmission version of the UL.

11. The method as claimed in claim 8 , wherein the data transmission format comprises a coded version.

12. A terminal equipment, comprising a processor, a transceiver and a memory, wherein the memory is configured to store instructions, and the processor is configured to call the instructions of the memory to execute the following operations:
determining a first data transmission format, the first data transmission format being used in generating a first transmission version of uplink (UL) data;
