Method and device for parallel polar code encoding/decoding

An apparatus comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• transmit at least a first segment of information bits over a first set of sub-channels;
• and
• transmit at least a second segment of information bits, and a masked parity bit, over a second set of sub-channels, wherein a value of the masked parity bit is equal to a bitwise combination of a first parity bit computed from the first segment of information bits and a second parity bit computed from the second segment of information bits, the second set of sub-channels being different than the first set of sub-channels.

An apparatus comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive a first polar-encoded bit-stream carrying at least first segment of information bits over a first set of sub-channels;
• and
• receive a second polar-encoded bit-stream carrying at least a second segment of information bits and a masked parity bit over a second set of sub-channels, wherein a value of the masked parity bit is equal to a bitwise combination of a first parity bit computed from the first segment of information bits and a second parity bit computed from the second segment of information bits, the second set of sub-channels being different than the first set of sub-channels.
