1. A method performed in base station equipment for wireless communication, comprising:generating a first information block, wherein the first information block comprises K bits consisting of bits in M sub-information-blocks and Q padding bits, where M is a positive integer greater than one, Q is a non-negative integer, and K is a positive integer greater than one;

performing first channel coding, wherein a first bit block is used as an input for the first channel coding, the first channel coding is based on a polar code, the first bit block comprises the K bits and L check bits, and the first information block is used to generate the L check bits, where L is a positive integer; and

transmitting a first radio signal, wherein the output of the first channel coding is used to generate the first radio signal;

wherein any one of the M sub-information-blocks consists of a positive integer number of bits, a first sub-information-block is a sub-information-block of the M sub-information-blocks, and the first sub-information-block consists of P bits, where P is a positive integer; a value of the first sub-information-block is related to an information format of the first information block, or the value of the first sub-information-block is related to Q; the first information block and the L check bits are sequentially mapped into the first bit block after being interleaved, the positions of the P bits in the first bit block are prior to a first check bit, the first check bit is a check bit whose position is front-most among the L check bits in the first bit block, and both the previous adjacent bit and the next adjacent bit of the first check bit in the first bit block are bits in the first information block.

performing first channel coding, wherein a first bit block is used as an input for the first channel coding, the first channel coding is based on a polar code, the first bit block comprises the K bits and L check bits, and the first information block is used to generate the L check bits, where L is a positive integer; and

transmitting a first radio signal, wherein the output of the first channel coding is used to generate the first radio signal;

wherein any one of the M sub-information-blocks consists of a positive integer number of bits, a first sub-information-block is a sub-information-block of the M sub-information-blocks, and the first sub-information-block consists of P bits, where P is a positive integer; a value of the first sub-information-block is related to an information format of the first information block, or the value of the first sub-information-block is related to Q; the first information block and the L check bits are sequentially mapped into the first bit block after being interleaved, the positions of the P bits in the first bit block are prior to a first check bit, the first check bit is a check bit whose position is front-most among the L check bits in the first bit block, and both the previous adjacent bit and the next adjacent bit of the first check bit in the first bit block are bits in the first information block.
