Abstract
According to some embodiments, a method for use in a wireless transmitter of encoding a transport block comprises, upon determining a code rate for transmitting a transport block is less than or equal to R_threshold (R_threshold is between 1/5 and 1/3), selecting new radio (NR) low-density parity-check (LDPC) base graph 2 for encoding the transport block. The method further comprises encoding the transport block using the selected base graph and transmitting the encoded transport block to a wireless receiver.
Claims20
A method of wireless communication comprising:
- determining that at least one of a plurality of criteria is met, the plurality of criteria comprising at least:
- a coding rate (R) is less than or equal to 1/4, and
- a transport block size (TBS) is less than or equal to 3824 bits and the R is less than or equal to 2/3;
- encoding, based on the determining, code blocks of a transport block using low-density parity-check (LDPC) base graph 2, wherein a maximum code block size of each of the code blocks is 3840 bits;
- and
- transmitting the transport block.
A wireless transmitter comprising:
- a non-transitory memory;
- and
- processing circuitry coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the wireless transmitter to perform operations comprising:
- determining that at least one of a plurality of criteria is met, the plurality of criteria comprising at least:
- a coding rate (R) is less than or equal to 1/4, and
- a transport block size (TBS) is less than or equal to 3824 bits and the R is less than or equal to 2/3;
- encoding, based on the determining, code blocks of a transport block using low-density parity-check (LDPC) base graph 2, wherein a maximum code block size of each of the code blocks is 3840 bits;
- and
- transmitting the transport block.
A non-transitory computer-readable medium having stored thereon instructions executable by a processor to perform operations comprising:
- determining that at least one of a plurality of criteria is met, the plurality of criteria comprising at least:
- a coding rate (R) is less than or equal to 1/4, and
- a transport block size (TBS) is less than or equal to 3824 bits and the R is less than or equal to 2/3;
- encoding, based on the determining, code blocks of a transport block using low-density parity-check (LDPC) base graph 2, wherein a maximum code block size of each of the code blocks is 3840 bits;
- and
- transmitting the transport block.
