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: Certain aspects of the present disclosure relate to techniques and apparatus for design of hybrid automatic repeat request (HARQ) feedback bits. The method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of blocks, and partitioning each block of the plurality of blocks into a plurality of sections. The method also includes deriving redundancy check information for each section of the plurality of sections, and generating a plurality of codewords, each comprising a block of the plurality of blocks and the redundancy check information for each section of the block, wherein a location of each of the sections in the codewords is determined based on an error rate corresponding to each of the sections.

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: 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: intercalador para conformação de constelação. os aspectos da revelação se referem à comunicação sem fio com um formato de onda configurado de acordo com a conformação de constelação probabilística em conexão com a modulação. um dispositivo de transmissão sem fio pode determinar uma sequência de símbolos de amplitude de uma sequência de bits de informações usando um correspondente de distribuição (dm) configurado para conformação de amplitude probabilística. o dispositivo pode aplicar adicionalmente codificação de correção de erro para codificar um bloco de informações correspondente a pelo menos uma porção da sequência de símbolos de amplitude. e o dispositivo pode gerar uma sequência de símbolos de saída para transmissão com base no bloco de informações codificado. em vários exemplos, o dispositivo pode aplicar intercalação a um ou mais dentre a sequência de símbolos de amplitude, o bloco de informações, o bloco de informações codificado ou uma combinação da sequência de símbolos de amplitude e o bloco de informações codificado, para a geração da sequência de símbolos de saída. outros aspectos, modalidades e particularidades também são reivindicados e descritos.
