    摘要: Aspects of the present disclosure relate to parity-check matrix (P-matrix) rotation in low-density parity check (LDPC) coding. The P-matrix rotation may be performed by a plurality of shift registers, where each shift register is configured to receive a respective set of bits corresponding to a respective column in the P-matrix. Each cycle, the shift registers may then incrementally rotate their respective sets of bits to achieve a respective shift amount up to a maximum shift amount per cycle. During a cycle, if the shift amount produced by a shift register results in a degree of rotation corresponding to an element within the respective column of the P-matrix, the shift register may output the rotated set of bits for further processing.

    摘要: Aspects of the present disclosure relate to low density parity check (LDPC) encoding. At least a portion of the parity bits generated by an LDPC encoder for an initial transmission may be stored for use in generating subsequent hybrid automatic repeat request (HARQ) redundancy versions. In some examples, at least the degree-two and degree-three parity bits included in the initial transmission may be stored. The parity bits may be stored within a layer 2 (L2) or an upper layer buffer or within the LDPC encoder. For example, the parity bits may be stored within the HARQ buffer.

    摘要: A method, an apparatus, and a computer program product for data communication are provided. The method may include providing a plurality of data channels on a communications link, determining unused bandwidth as a difference between total bandwidth provided by the communications link and bandwidth used by the plurality of data channels, allocating the unused bandwidth to a virtual channel, scheduling the plurality of data channels and the virtual channel in accordance with a time-based multiplexing scheme, and disabling interface circuitry used to couple the transmitter to the communications link when the virtual channel is scheduled. Each of the plurality of data channels may be assigned to a source of data to be transmitted on the communications link.
