摘要： Various aspects of the disclosure relate to retransmission techniques for communication of information (e.g., for wireless communication). In some aspects, if a device's first transmission including encoded data and parity information (subject to puncture) fails, the device's retransmission (e.g., in response to a NAK) involves transmitting the parity information that was punctured. In some aspects, the coding rate used for encoding the data for the first transmission is selected to meet an error rate (e.g., a block error rate) for the second transmission. The second transmission may also include repetition information that includes the encoded data. The repetition information could also include at least a portion of the encoded parity information.

摘要： Various aspects of the disclosure relate to a HARQ scheme for communication of information (e.g., for wireless communication). In some aspects, if a device's first transmission including encoded data and punctured parity information fails, the device's second transmission (e.g., in response to a NACK) involves transmitting the encoded parity information in its entirety. In some aspects, the coding rate used for encoding the data for the first transmission is selected to meet an error rate (e.g., a block error rate) for the second transmission. The second transmission may also include repetition information that includes the encoded data. The repetition information could also include at least a portion of the encoded parity information.

摘要： Methods, systems, and devices for wireless communication are described. A transmitter may generate a first segmentation based on a first subset of control information and a second segmentation based on jointly encoding the first subset and a second subset of the control information. The transmitter may polar encode the first segmentation to generate a first codeword and the second segmentation to generate a second codeword, and transmit the first and second codewords. A receiver may determine a first bit sequence corresponding to the first subset based on decoding a first codeword and determine an error detection code (EDC) and a second bit sequence corresponding to the second subset based on decoding a second codeword. The receiver may perform error detection on the first and second bit sequences based on the determined EDC, and output the first bit sequence and the second bit sequence or a decoding error.

摘要： Various aspects of the disclosure relate to mapping different information to different sub-channels. For example, information for different users may be mapped to different Polar code sub-channels. In some aspects, the mapping may be unbalanced in that different information is mapped to different sub-channels according to the quality (e.g., in terms of error probability) of the sub-channels and a criterion associated with the information. For example, control information for users that are experiencing the worst channel quality (e.g., in a wireless communication channel) may be mapped to the Polar code sub-channels that have the best quality.

摘要： Methods, systems, and devices for wireless communication are described for mutual information based polar code construction. A wireless device may receive a codeword over a wireless channel, the codeword encoded using a polar code. The wireless device may identify a set of bit locations of the polar code corresponding to information bits of an encoded information bit vector. The set of bit locations may be determined based at least in part on a reliability order of the bit locations of the polar code, and the reliability order may be determined based at least in part on a recursive model that includes at least one mutual information transfer function that is applied at each polarization stage of multiple polarization stages of the polar code. The wireless device may decode the received codeword to obtain the information bit vector at the set of bit locations.

摘要： Techniques are described for wireless communication. One method includes identifying a set of punctured bit locations in a received codeword. The received codeword is encoded using a polar code. The method also includes identifying a set of information bit locations of the polar code, with the set of information bit locations being determined based at least in part on polarization weights per bit-channel of a polar code decoder that are a function of nulled repetition operations per layer of the polar code identified based at least in part on the set of punctured bit locations. The method further includes processing the received codeword using the polar code decoder to obtain an information bit vector at the set of information bit locations.
