Wireless communication with polar codes using a mask sequence for frozen bits

Abstract:

Wireless communication devices are adapted to facilitate information sequences included in frozen sub-channels of polar coded transmissions. According to one example, an apparatus can generate a mask sequence based on a plurality of parameters, including at least one of a transmitting-device-specific sequence or a receiving-device-specific sequence. In some examples, the frozen bits may be masked with the mask sequence, and an information block may be encoded utilizing polar coding. In other examples, the mask sequence may be compared to the frozen bits of a received information block, and the received information block may be determined as intended for the apparatus when the mask sequence matches to the frozen bits. Other aspects, embodiments, and features are also included.
