Communication method, terminal equipment, and network equipment

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.

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;
• 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, through the transceiver, a first scheduling assignment message to a 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 modulating the coded UL data to generate the first transmission version;
• and
• sending, through the transceiver, 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.

A network 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:

• receiving, through the transceiver, a scheduling assignment message sent by a 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;

• 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.
