Techniques for employing polar code in connection with nr (new radio)

An apparatus configured to be employed in a BS (Base Station), comprising:

• a memory;
• and
• one or more processors configured to, when executing instructions stored in the memory, cause the BS to:
• transmit configuration information to a User Equipment (UE), the configuration information instructs the UE to:
• determine one or more thresholds for code block segmentation that include a payload threshold (Kseg);
• determine to perform code block segmentation based on the one or more thresholds and a current payload (K) of an uplink control information (UCI);
• segment the UCI into a plurality of code block segments;
• encode each code block segment of the plurality of code block segments via a polar encoder;
• perform rate matching per code block segment of the plurality of code block segments;
• subsequent to rate matching, perform bit level interleaving per code block segment of the plurality of code block segments;
• and
• transmit the plurality of code block segments by an uplink control channel.

A method performed by a Base Station (BS), the method comprising:

• transmit configuration information to a User Equipment (UE), the configuration information causing the UE to:
• perform code block segmentation on an uplink control information (UCI), for transmission on an uplink control channel, forming a plurality of code block segments;
• encode each code block segments of the plurality of code block segments via a polar encoder;
• perform rate matching per code block segment of the plurality of code block segments, after rate matching, perform bit level interleaving per code block segment of the plurality of code block segments;
• and
• transmit the plurality of code block segments on an uplink control channel.
