Abstract: Aspects of the disclosure relate to wireless communication devices configured to encode information blocks to produce code blocks and interleave the code blocks utilizing an interleaver including a plurality of rows and a plurality of columns, where the number of columns of the interleaver varies between the rows. In some examples, the interleaver includes a right isosceles triangle-shaped matrix of rows and columns. In other examples, the interleaver includes a trapezoid-shaped matrix of rows and columns.

Abstract: Aspectos de la divulgación se refieren a dispositivos de comunicación inalámbrica configurados para codificar bloques de información para producir bloques de código y entrelazar los bloques de código utilizando un entrelazador que incluye una pluralidad de filas y una pluralidad de columnas, donde el número de columnas del entrelazador varía entre las filas. En algunos ejemplos, el entrelazador incluye una matriz en forma de triángulo isósceles recto de filas y columnas. En otros ejemplos, el entrelazador incluye una matriz en forma de trapezoide de filas y columnas.

Abstract: Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing schemes consider punctured bits as unknown bits, and set the log likelihood ratio (LLR) for those bits to zero; while other puncturing schemes consider punctured bits as known bits, and set the LLR for those bits to infinity. Each of these puncturing schemes has been observed to provide benefits over the other under different circumstances, especially corresponding to different coding rates or different signal to noise ratio (SNR). According to aspects of the present disclosure, both puncturing schemes are compared, and the puncturing scheme resulting in the better performance is utilized for transmission.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for dynamic frozen polar codes, for example, for control channels. An exemplary method may be performed at the encoder. The method generally includes encoding a stream of bits using a polar code. The encoding includes selecting a first set of channel indices for encoding information bits. The encoding includes selecting a second set of the channel indices smaller than a channel index for a first information bit for encoding fixed frozen bits. The encoding includes selecting remaining channel indices for dynamic frozen (PCF) bits having values based on one or more of the information bits. The method includes transmitting the encoded stream of bits.

Abstract: Various aspects of the disclosure relate to rate matching techniques for block encoding. In some aspects, a decision regarding whether to use repetition-based rate matching or puncture-based rate matching is made based on a block size of information being encoded. In some aspects, repetition-based rate matching uses a bit-reversal permutation technique.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may perform a first transmission of a communication that is encoded using a polar coding technique; and perform at least one retransmission of the communication, wherein more resources are allocated for the at least one retransmission than for the first transmission, and wherein the at least one retransmission includes an incremental redundancy version of the communication and a version of the communication for Chase combination. Numerous other aspects are provided.
