Method and device for transmitting data

An apparatus in a communication device, comprising:

• a processor and a memory storing program instructions;
• wherein when the program instructions are executed by the processor, the apparatus is configured to:
• obtain a bit sequence, wherein the bit sequence comprises K bits of information, and K is a positive integer;
• encode the bit sequence to obtain a first encoded sequence, wherein the first encoded sequence comprises N bits, N is greater than or equal to K, and N is an integer power of 2;
• block interleave the first encoded sequence, to obtain an interleaved bit sequence;
• obtain a target code length M, wherein M is a positive integer smaller than N;
• and
• when a transmission code rate K÷M is less than a code rate threshold, obtain a second bit sequence of M bits by puncturing (N−M) bits from beginning of the interleaved bit sequence;
• and
• output the second bit sequence.

A microchip, comprising one or more integrated circuits that are configured to:

• obtain a bit sequence, wherein the bit sequence comprises K bits of information, and K is a positive integer;
• encode the bit sequence to obtain a first encoded sequence, wherein the first encoded sequence comprises N bits, N is greater than or equal to K, and N is an integer power of 2;
• block interleave the first encoded sequence, to obtain an interleaved bit sequence;
• obtain a target code length M, wherein M is a positive integer smaller than N;
• when a transmission code rate K÷M is less than a code rate threshold, obtain a second bit sequence of M bits by puncturing (N−M) bits from beginning of the interleaved bit sequence;
• and
• output the second bit sequence.

A method for processing data in a wireless communication network, comprising:

• obtaining, by an information processing device, a bit sequence, wherein the bit sequence comprises K bits of information, and K is a positive integer;
• encoding, by the device, the bit sequence to obtain a first encoded sequence, wherein the first encoded sequence comprises N bits, N is greater than or equal to K, and N is an integer power of 2;
• block interleaving, by the device, the first encoded sequence, to obtain an interleaved bit sequence;
• obtaining, by the device, a target code length M, wherein M is a positive integer smaller than N;
• and
• when a transmission code rate K÷M is less than a code rate threshold, outputting, by the device, a second bit sequence of M bits by puncturing (N−M) bits from beginning of the interleaved bit sequence.
