Abstract
Systems and methods are disclosed herein for puncturing Polar-encoded bits. In some embodiments, a method of operation of a radio node that utilizes a Polar encoder comprising performing Polar encoding of a plurality of bits to provide a plurality of Polar-encoded code bits and puncturing the plurality of Polar-encoded code bits using a hybrid puncturing scheme to provide a plurality of rate-matched Polar-encoded code bits.

A method of operation of a radio node that utilizes a Polar encoder, comprising:
- performing Polar encoding of a plurality of bits to provide a plurality of Polar-encoded code bits;
- and
- puncturing the plurality of Polar-encoded code bits using a hybrid puncturing scheme to provide a plurality of rate-matched Polar-encoded code bits;
- where puncturing the plurality of Polar-encoded bits using the hybrid puncturing scheme to provide the plurality of rate-matched Polar-encoded code bits comprises:
- re-ordering the plurality of Polar-encoded code bits to provide a plurality of re-ordered Polar-encoded code bits;
- and
- storing the plurality of re-ordered Polar-encoded code bits in a circular buffer or linear buffer.
