Sidelink control information processing

An apparatus configured for inclusion within a user equipment (UE) device, the apparatus comprising:

• a non-transitory computer-readable memory medium;
• and
• a processor in communication with the memory medium, wherein the processor and the memory medium are configured to cause the UE device to:
• polar encode first sidelink control information to obtain polar encoded first sidelink control information, wherein the first sidelink control information comprises second stage sidelink control information;
• perform rate matching on the polar encoded first sidelink control information;
• determine a result of a cyclic redundancy check performed on second sidelink control information received over a physical sidelink control channel (PSCCH);
• scramble the polar encoded first sidelink control information based at least in part on the result of the cyclic redundancy check;
• and
• transmit the scrambled polar encoded first sidelink information to a remote device on a physical sidelink shared channel (PSSCH).
