Title: METHOD FOR SENDING AND RECEIVING FEEDBACK INFORMATION, ACCESS NETWORK DEVICE AND TERMINAL DEVICE
Abstract:
This application provides a method for sending feedback information, which can improve system transmission efficiency. The method comprises: a terminal device receiving a transport block TB sent by an access network device in a first transmission time interval TTI, the TB comprising at least two coding blocks CB including a first portion CB and a second portion CB; and if the terminal device receives the second portion CB sent by the access network device in the second TTI and does not receive the first portion CB, the terminal device sends first feedback information and second feedback information to the access network device, the first feedback information being for feeding back whether the terminal device decodes the first portion CB correctly, and the second feedback information being for feeding back whether the terminal device correctly decodes the second portion CB, wherein the second TTI is later than the first TTI in a time sequence.
