Abstract
Methods, systems, and devices for wireless communications are described. In some systems, wireless devices may encode and decode transmissions using polar codes. A transmitting device may encode a payload based on a selected payload size. For example, the transmitting device may construct a bit vector including payload bits, parity bits, frozen bits, or some combination of these, and may modify the bits or the order of the bits based on the selected payload size. The device may generate a polar-encoded codeword based on this bit vector, and may transmit the polar-encoded codeword to a receiving device. The receiving device may blind decode the polar-encoded codeword, and may determine the correct payload size based on the decoded bit vector. For example, the device may perform decoding or may check decoded bits based on a payload size hypothesis, where the decoding may fail for any incorrect payload size hypothesis.
