Hybrid Automatic Repeat Request Feedback Method and Device

A terminal device, comprising:

• a processor and a transceiver;
• wherein
• the transceiver is configured to send data to be transmitted to a network device;
• the processor is configured to determine whether the transceiver receives feedback information for the data to be transmitted in a first target time period, wherein a start time point of the first target time period is a time point that the transceiver finishes sending the data to be transmitted, and a time length of the first target time period is a first time length;
• and
• the transceiver is further configured to send feedback request information to the network device when the processor determines that the transceiver does not receive feedback information for the data to be transmitted in the first target time period, wherein the feedback request information is used for requesting the network device to send feedback information for the data to be transmitted.
