Claim of US Patent No. 10,707,989

1. A method for use in a base station equipment for wireless communication, comprising:generating a first information block, wherein the first information block consists of bits in M sub-information blocks and Q padding bits, where the M is a positive integer greater than one, and the Q is a non-negative positive integer;
performing first channel coding, wherein the first channel coding is based on a polar code, a first bit block is used for an input of the first channel coding, the first information block and the first check bit block are interleaved to generate the first bit block, and the first information block is used to generate the first check bit block; and
transmitting a first radio signal, wherein the output of the first channel coding is used to generate the first radio signal;
wherein a first bit and a second bit are two bits in the first information block;
a first sub-information block is one of the M sub-information blocks; both the first bit and the second bit belong to the first sub-information block, there is at least one bit that does not belong to the first sub-information block locating between the positions of the first bit and the second bit in the first information block, or the first bit and the second bit belong to the Q padding bits, and there is at least one bit belonging to the M sub-information blocks locating between the positions of the first bit and the second bit in the first information block; and
wherein the M sub-information blocks are sequentially cascaded with the Q padding bits to generate a second information block, and the second information block is interleaved to generate the first information block.
