Abstract
A method in a node (110, 115) comprises generating (604) a plurality of constituent polar codes, each of the plurality of constituent polar codes having an associated block length and an associated set of information bits. The method comprises coupling (608) at least a portion of the sets of information bits associated with each of the plurality of constituent polar codes to generate a spatially coupled polar code. The method comprises encoding (612) a wireless transmission using the spatially coupled polar code.

A method in a node, comprising:
- coupling at least a portion of sets of information bits associated with each of a plurality of constituent polar codes to generate a spatially coupled polar code, each of the plurality of constituent polar codes having an associated block length and an associated set of information bits;
- encoding a wireless transmission using the spatially coupled polar code;
- transmitting the wireless transmission from the node to another node;
- and
- the at least a portion of the sets of information bits associated with each of the plurality of constituent polar codes being coupled using a coupling matrix that specifies how information bits from a first constituent polar code of the plurality of constituent polar codes are coupled to one or more other constituent polar codes of the plurality of constituent polar code, and the coupling matrix being expressed as a block-wise upper triangular form.
