Methods and devices for transmitting feedback information, and recording materials

Abstract

The invention relates to a method and apparatus for transmitting response information, and a recording device. The method of communicating feedback includes the following steps: Upon reception, via the first node, the target information group is sent by the second node, where each target information detail in the target information group has a first information field and a second information field, the first information field contains M bits of response information to the group of data channels or group of transmission resources, M is a positive integer, The second information field is used to determine the corresponding relationship between the first information field and the group of data channels or the group of transmission resources.
