Polar coded hybrid automatic repeat request (HARQ) with incremental channel polarization

A wireless communication device, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• perform a first polar encoding process on a first transmission of a hybrid automatic repeat request (HARQ) process;
• generate a second transmission of the HARQ process by relocating a portion of bits in less reliable positions of the first transmission to more reliable positions of the second transmission of the HARQ process,
• wherein the less reliable positions and the more reliable positions are evaluated based at least in part on a channel transform matrix,
• wherein the channel transform matrix is based at least in part on the first transmission, the second transmission, the first polar encoding process and a second polar encoding process associated with the second transmission;
• and
• transmit the second transmission of the HARQ process.

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 a wireless communication device, cause the one or more processors to:
• perform a first polar encoding process on a first transmission of a hybrid automatic repeat request (HARQ) process;
• generate a second transmission of the HARQ process by relocating a portion of bits in less reliable positions of the first transmission to more reliable positions of the second transmission of the HARQ process,
• wherein the less reliable positions and the more reliable positions are evaluated based at least in part on a channel transform matrix,
• wherein the channel transform matrix is based at least in part on the first transmission, the second transmission, the first polar encoding process and a second polar encoding process associated with the second transmission;
• and
• transmit the second transmission of the HARQ process.
