METHOD AND APPARATUS FOR SENDING AND RECEIVING FEEDBACK INFORMATION
FIG2 is a schematic diagram of a CBG division method according to this application
FIG2 is a schematic diagram of a TB division manner according to this application. As shown in FIG2, a first TB includes 42 CBs, which are mapped to 12 time domain symbols in a sequence of a frequency domain first and a time domain next, and the first TB is divided into 12 CBGs based on dimensions of the time domain symbols. Because a frequency domain resource corresponding to a single time domain symbol is limited, some CBs cannot be mapped to a same time domain symbol. For example, a CBG 1 includes a CB 1 to a CB 4, a CBG 2 includes the CB 4 to a CB 7, and the CB 4 is a common CB for the CBG 1 and the CBG 2.

The method according to claim 11, wherein when the type of the PUCCH is a short PUCCH, and a terminal device sends, in a slot in which the short PUCCH is located, uplink data information or information carried by a long uplink control channel, the second feedback information is used to feed back the receiving status of each of the N TBs.']
