IMPROVING THE PERFORMANCE OF A DATA CHANNEL USING POLAR CODES FOR A WIRELESS COMMUNICATION SYSTEM

摘要

Various embodiments provide for encoding and decoding data channel information with polar codes where the frozen bits of the information block can be set to a scrambling identifier based on the device ID, cell ID, or some other unique identifier 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 data link data, the frozen bits can be coded with the scrambling identifier. In an example where there are more frozen bits than bits in the scrambling identifier, the most reliable of the frozen bits can be coded with the scrambling identifier. In another example, the frozen bits can be set to the CRC bits, which can then be masked by the scrambling identifier.
