A method for processing feedback information, applied in a first transmission node, comprising: the first transmission node receiving a signal of a data shared channel, and determining data transmission level indication information of a transport block according to the signal, wherein the data transmission level indication information is used to indicate a data transmission level; and the first transmission node transmitting the data transmission level indication information of the transport block to a second transmission node, wherein the data transmission level indication information comprises soft Acknowledgement ACK/Negative Acknowledgement NACK information, wherein the soft ACK/NACK information is joint-coded indication information of error level indication information and the ACK information, wherein if data of the transport block is decoded erroneously, the error level indication information is used to indicate level information of an error pattern level, wherein the level information comprises code block set error pattern level information, wherein the error level indication information indicates N levels, and different error levels indicate different code block set error pattern levels; and the transport block is divided into M code blocks which are divided into N0 sets; wherein N0 is an integer greater than or equal to 2, and M and N are equal to or greater than N0, and the code block set error pattern level indication information is used to indicate whether each code block set is decoded erroneously, wherein if at least one code block in the code block set has a decoding error, the code block set is an erroneous code block set. the first transmission node receiving a signal of a data shared channel, and determining data transmission level indication information of a transport block according to the signal, wherein the data transmission level indication information is used to indicate a data transmission level; and the first transmission node transmitting the data transmission level indication information of the transport block to a second transmission node, wherein the data transmission level indication information comprises soft Acknowledgement ACK/Negative Acknowledgement NACK information, wherein the soft ACK/NACK information is joint-coded indication information of error level indication information and the ACK information, wherein if data of the transport block is decoded erroneously, the error level indication information is used to indicate level information of an error pattern level, wherein the level information comprises code block set error pattern level information, wherein the error level indication information indicates N levels, and different error levels indicate different code block set error pattern levels; and the transport block is divided into M code blocks which are divided into N0 sets; wherein N0 is an integer greater than or equal to 2, and M and N are equal to or greater than N0, and the code block set error pattern level indication information is used to indicate whether each code block set is decoded erroneously, wherein if at least one code block in the code block set has a decoding error, the code block set is an erroneous code block set.
