To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolar- ized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.

Abstract: RESUMEN Se describen métodos, sistemas, y dispositivos para comunicación inalámbrica. Con el fin de intercambiar datos a través de una red de comunicaciones inalámbricas, un dispositivo inalámbrico puede llevar a cabo, en primer lugar, un procedimiento de adquisición de celdas (por ejemplo, para determinar información específica de celda, tal como desplazamientos de temporización y de frecuencia, ancho de banda, formateo del canal de control, etc.). En algunos sistemas, se pueden transmitir aspectos de la información de temporización con códigos de aleatorización aplicados a un bloque de información maestro (MIB). Las cargas útiles del canal de difusión físico (PBCH), que incluyen transmisiones MIB, se pueden codificar de manera conjunta con índices de señal de sincronización. De este modo, las ráfagas de transmisiones MIB se pueden decodificar sin decodificación ciega y a la vez mantener la protección contra errores y latencia baja que puede ser necesaria para obtener información crítica del sistema en el MIB.

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 for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

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.
