1. A method for feedback information transmission, comprising: transmitting, by a terminal device, a group of data channels to a base station, wherein the group of data channels comprises N transport blocks (TBs) or code block groups (CBGs) that correspond to N bits of feedback information, and N is a positive integer;
receiving, by the terminal, a group of target information from the base station, wherein the group of target information comprises at least a piece of target information, each piece of target information in the group of target information comprises a first information field and a second information field, the first information field comprises M bits of feedback information for the group of data channels, and the second information field is used for determining a correspondence between the first information field and the group of data channels, M being a positive integer,
wherein each piece of target information in the group of target information is transmitted in a constant size DCI so as to transmit the N bits of feedback information through the group of target information, and wherein the group of target information comprises P pieces of target information transmitted in P constant size DCIs, where P is a positive integer,
wherein when unused bits remain in the last transmitted constant size DCI, a third information field containing padding information is transmitted, and
wherein when the value of M is less than the value of N, P is greater than 1.
