US Patent 10277252 Encoding data with polar codes for control channels

Various embodiments provide for encoding and decoding control link information with polar codes where the frozen bits of the information block can be set to the device identification number instead of being set to null. The frozen bits can be identified based on the type of polar code being used, and while the non-frozen bits can be coded with the channel state information, the frozen bits can be coded with the device ID. In an example where there are more frozen bits than bits in the device ID, the most reliable of the frozen bits can be coded with the device ID. In another example, the frozen bits can be set to the CRC bits, which can then be masked by the device ID.
