Method and device for storing and decoding hybrid automatic repeat request transmission block

A method for decoding an HARQ transmission block, comprising:

• obtaining the HARQ transmission block during a downlink signal transmission, wherein the transmission block comprises at least one code block;
• storing the code block of the at least one code block that cannot be correctly decoded to a divided storage space of a buffer;
• recording starting addresses of bits of the code block stored during a first time and during a second time in the storage space of the buffer, respectively, wherein the storage space of the buffer is dynamically divided in a unit of code blocks;
• after obtaining a bit of the code block transmitted during a third time, obtaining the bits of the code block stored during the first time and during the second time according to the recorded starting addresses of the code block stored during the first time and during the second time in the storage space of the buffer, respectively;
• and
• combining the obtained bits of the code block stored during the first time and during the second time with the obtained bit of the code block transmitted during the third time in a pack buffer to decode the code block;
• wherein, when the storage space of the buffer is dynamically divided in a unit of code blocks before obtaining the at least one code block, the storage space of the buffer is dynamically divided in a unit of a largest code block;
• and
• wherein, when the storage space of the buffer is dynamically divided in a unit of code blocks after obtaining the at least one code block, the storage space of the buffer is dynamically divided in a unit of a code block that cannot be correctly decoded.
