Claim 5:
6. The method of claim 4 wherein:
the different puncturing patterns comprise the first puncturing pattern for the first code rate region and the second puncturing pattern for the second code rate region, wherein the first puncturing pattern and the second puncturing pattern are mutually complementary puncturing patterns;
the plurality of Polar-encoded code bits comprises N bits; and
puncturing the plurality of Polar-encoded code 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;
storing the plurality of re-ordered Polar-encoded code bits in a circular buffer or linear buffer;
extracting a first M bits from the circular buffer or the linear buffer as the plurality of rate-matched Polar-encoded code bits in accordance with the first puncturing pattern for the first puncturing scheme if a desired code rate for the plurality of rate-matched Polar-encoded code bits is within the first code rate region; and
extracting M bits from the circular buffer or the linear buffer starting at an (N−M)-th bit of the circular buffer or the linear buffer as the plurality of rate-matched Polar-encoded code bits in accordance with the second puncturing pattern for the second puncturing scheme if the desired code rate for the plurality of rate-matched Polar-encoded code bits is within the second code rate region;
wherein M<N.
