Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for coded-bit allocation for UCI segmentation. An exemplary method that may be performed by a wireless device generally includes generating coded bits of uplink control information (UCI) to be transmitted as one or more segments, applying one or more rules to ensure an integer number of bits are allocated to each of the one or more segments, and transmitting the UCI in the segments according to the assignment.

Abstract: RESUMEN Se describen métodos, sistemas y dispositivos para comunicaciones inalámbricas. Un dispositivo inalámbrico puede recibir información de control de enlace descendente que corresponde a una transmisión de un bloque de transporte a través de una pluralidad de intervalos de tiempo de transmisión (TTI). El dispositivo inalámbrico puede identificar una secuencia de versión de redundancia para el bloque de transporte. La versión de redundancia puede ser una secuencia predefinida o puede estar configurada por señalización de capa superior con base en un criterio de secuencia. El dispositivo inalámbrico puede transmitir o recibir una pluralidad de versiones de redundancia del bloque de transporte en la pluralidad de TTI con base, al menos en parte, en la secuencia de versión de redundancia. En algunos ejemplos, la pluralidad de versiones de redundancia puede estar determinada con base, al menos en parte, en una versión de redundancia inicial identificada por otro dispositivo inalámbrico.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive downlink control information corresponding to a transmission of a transport block over a plurality of transmission time intervals (TTIs). The wireless device may identify a redundancy version sequence for the transport block. The redundancy version may be a pre-defined sequence or may be configured by higher layer signaling based on sequence criterion. The wireless device may transmit or receive a plurality of redundancy versions of the transport block in the plurality of TTIs based at least in part on the redundancy version sequence. In some examples, the plurality of redundancy versions may be determined based at least in part on a starting redundancy version identified by another wireless device.

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: Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing LDPC base graphs. Two or more LDPC base graphs may be maintained that are associated with different ranges of overlapping information block lengths. A particular LDPC base graph may be selected for an information block based on the information block length of the information block. Additional metrics that may be considered when selecting the LDPC base graph may include the code rate utilized to encode the information block and/or the lift size applied to each LDPC base graph to produce the information block length of the information block.

Abstract: Certain aspects of the present disclosure provide quasi-cyclic low-density parity-check (QC-LDPC) codes having pair-wise orthogonality of adjacent rows of the corresponding base matrices, and a new decoder (e.g. layered decoder) that exploits the pairwise row orthogonality for flexible decoder scheduling without performance loss, for example by decoding sequentially row by row in the base matrix or by decoding the pairs of orthogonal rows in the base matrix at a time. An apparatus includes a receiver configured to receive a codeword in accordance with a radio technology across a wireless channel via one or more antenna elements situated proximal the receiver. The apparatus includes at least one processor coupled with a memory and comprising decoder circuitry configured to decode the codeword based on a QC-LDPC code to produce a set of information bits. The LDPC code is stored in the memory and defined by a base matrix having columns in which all adjacent rows are orthogonal in a last portion of the rows.
