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: 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: Methods, systems, and devices for wireless communication are described. In order to exchange data over a given wireless communication network, a wireless device may first perform a cell acquisition procedure (e.g., to determine cell-specific information such as timing and frequency offsets, bandwidth, control channel formatting, etc. ). In some systems, aspects of the timing information may be conveyed with scrambling codes applied to a master information block (MIB). Physical broadcast channel (PBCH) payloads, including MIB transmissions, may be jointly encoded with synchronization signal indices. Bursts of MIB transmissions may thus be decoded without blind decoding while maintaining error protection and low latency that may be necessary to obtain critical system information within the MIB.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communication are described that support channel selection for parity bits in polar coding techniques. In some cases, an encoder or decoder of a wireless device may assign information bits, frozen bits, and parity check bits to polar channels of an encoder or decoder based on reliability metrics. The information bits may initially be assigned and based on a channel index of the first information bit, the parity check bits may be assigned to channels having higher channel indices than the first information bit. After assignment, the bits may be encoded or decoded.
