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, whether the transport block is decoded successfully or not is based on Transport Block Cyclic Redundancy Check, TB CRC, wherein if the transport block is decoded correctly, an ACK is generated based on the TB CRC, wherein if 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 error 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 code block sets; wherein N0 is an integer greater than or equal to 2, and M and N are equal to or greater than N0, wherein the transport block comprises one or more code blocks, and each code block of the transport block has a code block CRC, wherein whether a code block of the transport block is decoded successfully or not is based on the code block CRC of the code block, and the code block set error pattern level information is used to indicate whether each code block set of the transport block is decoded erroneously, wherein if at least one code block in a code block set of the transport block 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, whether the transport block is decoded successfully or not is based on Transport Block Cyclic Redundancy Check, TB CRC, wherein if the transport block is decoded correctly, an ACK is generated based on the TB CRC, wherein if 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 error 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 code block sets; wherein N0 is an integer greater than or equal to 2, and M and N are equal to or greater than N0, wherein the transport block comprises one or more code blocks, and each code block of the transport block has a code block CRC, wherein whether a code block of the transport block is decoded successfully or not is based on the code block CRC of the code block, and the code block set error pattern level information is used to indicate whether each code block set of the transport block is decoded erroneously, wherein if at least one code block in a code block set of the transport block has a decoding error, the code block set is an erroneous code block set.
