    Abstract: Concepts and schemes pertaining to quasi-cyclic-low-density parity-check (QC-LDPC) coding are described. A processor of an apparatus may generate a QC-LDPC code having a plurality of codebooks embedded therein. The processor may select a codebook from the plurality of codebooks. The processor may also encode data using the selected codebook. Alternatively or additionally, the processor may generate the QC-LDPC code including at least one quasi-row orthogonal layer. Alternatively or additionally, the processor may generate the QC-LDPC code including a base matrix a portion of which forming a kernel matrix that corresponds to a code rate of at least a threshold value.

    Abstract: Concepts and schemes pertaining to information coding for mobile communications are described. A processor of an apparatus encodes data to provide encoded data. The processor also transmits the encoded data to a network node of a wireless network. In encoding the data, the processor encodes the data with a low-density parity-check (LDPC) code to provide LDPC-coded data. Moreover, the processor processes the LDPC-coded data with a forward error correction (FEC) robustness enhancement function to provide the encoded data. The FEC robustness enhancement function includes an interleaving function that interleaves the LDPC-coded data to provide the encoded data, an interlacing function that interlaces the LDPC-coded data to provide the encoded data, or a bit-reordering function that reorders bits of the LDPC-coded data to provide the encoded data.

    Abstract: Concepts and examples pertaining to combined coding design for efficient codeblock extension are described. A processor of a communication apparatus may combine channel polarization of a communication channel with a first coding scheme for first codeblocks of a smaller size to generate a second coding scheme. The processor may also code second codeblocks of a larger size using the second coding scheme.

    Abstract: An apparatus for interference cancellation includes: a front end processing circuit, for receiving at least an interference signal and a desire signal; an inner processing circuit, for channel/noise estimation and for suppressing the interference signal; and a MIMO (multi-input multi-output) processing circuit, for blindly detecting an interference parameter of the interference signal based on the suppressed interference signal, and for jointly cancelling the interference signal from the desire signal and for demodulating the desire signal based on the detected interference parameter and the channel/noise estimation from the inner processing circuit.

    Abstract: Examples pertaining to bit selection for polar coding incremental-redundancy hybrid automatic repeat request (IR-HARQ) are described. An apparatus (e.g., UE) generates a re-transmission polar code block (CB) in a polar incremental redundancy HARQ (IR-HARQ) procedure. The apparatus then transmits the re-transmission polar CB as a re-transmission of an initial transmission of an initial polar code carrying a plurality of information bits. In generating the re-transmission polar CB, the apparatus selects one or more re-transmission information bits from the plurality of information bits.
