Abstract
This application discloses a grant-free transmission method, a network device, and a terminal device. The method includes: detecting, by a network device, a pilot sequence used by a terminal device for uplink transmission; determining, by the network device, a pilot sequence index of the pilot sequence based on the pilot sequence and a correspondence between the pilot sequence and the pilot sequence index; and sending, by the network device, information about a feedback result of the uplink transmission to the terminal device based on the pilot sequence index.

A method comprising:
- detecting, by a network device, a pilot sequence used by a terminal device for a grant-free uplink transmission transmitted by the terminal device to the network device;
- determining, by the network device, a pilot sequence index of the pilot sequence based on the pilot sequence and a correspondence between the pilot sequence and the pilot sequence index;
- and
- sending, by the network device, information about a feedback result of the uplink transmission to the terminal device using the pilot sequence index, the feedback result indicating whether or not the uplink transmission is received by the network device successfully.
A method comprising:
- determining, by a terminal device, based on a pilot sequence used for a grant-free uplink transmission and a correspondence between the pilot sequence and a pilot sequence index, the pilot sequence index of the pilot sequence, the uplink transmission being sent by the terminal device to a network device;
- receiving, by the terminal device from the network device, information that is about a feedback result of the uplink transmission, the feedback result indicating whether or not the uplink transmission is received by the network device successfully, and the feedback result being indicated using the pilot sequence index;
- and
- determining, by the terminal device, the feedback result of the uplink transmission based on the pilot sequence index and the information about the feedback result of the uplink transmission.
A network device comprising a processor, a transceiver, and a memory, wherein the memory is configured to store an instruction, the processor is configured to execute the instruction stored in the memory, and when the processor executes the instruction stored in the memory, the network device is enabled to implement steps of:
- detecting a pilot sequence used by a terminal device for a grant-free uplink transmission transmitted by the terminal device to the network device;
- determining a pilot sequence index of the pilot sequence based on the pilot sequence and a correspondence between the pilot sequence and the pilot sequence index;
- and
- sending information about a feedback result of the uplink transmission to the terminal device using the pilot sequence index, the feedback result indicating whether or not the uplink transmission is received by the network device successfully.
A terminal device comprising a processor, a transceiver, and a memory, wherein the memory is configured to store an instruction, the processor is configured to execute the instruction stored in the memory, and when the processor executes the instruction stored in the memory, the terminal device is enabled to implement steps:
