Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an encoding device may determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded; may determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits; may add the codeword bit to the codeword; and may transmit the codeword. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by an encoding device, comprising:
- determining a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded;
- determining a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits;
- adding the codeword bit to the codeword;
- and
- transmitting the codeword.
An encoding device for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded;
- determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits;
- add the codeword bit to the codeword;
- and
- transmit the codeword.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of an encoding device, cause the one or more processors to:
- determine a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded;
- determine a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits;
- add the codeword bit to the codeword;
- and
- transmit the codeword.
An apparatus for wireless communication, comprising:
- means for determining a least reliable subset of information bits included in a set of information bits that includes a predefined active set of information bits to be encoded;
- means for determining a codeword bit to be added to a codeword based at least in part on the least reliable subset of information bits, wherein adding the codeword bit to the codeword improves reliability of the least reliable subset of information bits;
- means for adding the codeword bit to the codeword;
- and
- means for transmitting the codeword.
