    Abstract: Various examples and schemes pertaining to multiple semi-static grant activation and deactivation by a single downlink control information (DCI) transmission in mobile communications are described. An apparatus receives, from a wireless network, a dynamic signaling. The apparatus then activates or deactivates, according to the dynamic signaling, one or more grant configurations associated with one or more configured grants of a plurality of configured grants related to transmissions or receptions with respect to the apparatus.

    Abstract: Aspects of the disclosure provide an apparatus and a method for error correction based on a matrix. The apparatus includes memory and processing circuitry. The memory is configured to store the matrix associated with a set of parity bits. The matrix having rows and columns includes elements having values corresponding to either a first state or a second state. The matrix also includes a row having two elements with values corresponding to the first state. One of the two elements is a parity element corresponding to a parity bit associated with the row. Further, other elements in a same column as the parity element have values corresponding to the second state. The processing circuitry is configured to implement error correction based on the matrix. In another embodiment, the processing circuitry is configured to encode a data unit by generating the set of parity bits from the data unit based on the matrix and to form a codeword that includes the data unit and the set of parity bits. The processing circuitry is also configured to decode a received codeword having a received data unit based on the matrix and to obtain a decoded data unit.

    Abstract: Sidelink vehicle-to-everything (V2X) transmission is performed over a Physical Sidelink Control Channel (PSCCH) and a Physical Sidelink Shared Channel (PSSCH). Encoded control information is transmitted in the PSCCH and encoded data is transmitted in the PSSCH. The PSCCH uses a first portion of the time-and-frequency resources, and the PSSCH uses and a second portion of the time-and-frequency resources. A first part of the PSSCH uses a first set of time resources overlapping with the PSCCH and a first set of frequency resources non-overlapping with the PSCCH. A second part of the PSSCH uses a second set of time resources non-overlapping with the PSCCH and a second set of frequency resources overlapping with the PSCCH.

    Abstract: A processor of an apparatus establishes a wireless communication link with at least one other apparatus via a transceiver of the apparatus. The processor wirelessly communicates with the other apparatus via the wireless communication link by: selecting a first shift-coefficient table from a plurality of shift-coefficient tables; generating a QC-LDPC code using a base matrix and at least a portion of the first shift-coefficient table; selecting a codebook from a plurality of codebooks embedded in the QC-LDPC code; storing the selected codebook in a memory associated with the processor; encoding data using the selected codebook to generate a plurality of modulation symbols of the data; and controlling the transceiver to multiplex, convert, filter, amplify and radiate the modulation symbols as electromagnetic waves through one or more antennas of the apparatus to transmit the modulation symbols of the data to the other apparatus via the wireless communication link.

    Abstract: Concepts and schemes pertaining to location of interleaver with low-density parity-check (LDPC) code are described. A processor of an apparatus encodes data to provide a stream of encoded data. The processor also rate matches the encoded data to provide a rate-matched stream of encoded data. The processor further interleaving the rate-matched stream of encoded data. In rate matching the encoded data, the processor buffers the stream of encoded data in a circular buffer, with the circular buffer functioning as a rate matching block that rate matches the stream of encoded data. In interleaving the rate-matched stream of encoded data, the processor performs bit-level interleaving on the rate-matched stream of encoded data to provide a stream of interleaved data.

    Abstract: Aspects of the disclosure provide an apparatus that includes transmitting circuit and processing circuit. The transmitting circuitry is configured to transmit wireless signals. The processing circuitry is configured to encode a set of information bits with a code that is configured for incremental redundancy to generate a code word that includes the information bits and parity bits, buffer the code word in a circular buffer, determine a start position in the circular buffer based on a redundancy version that is selected from a plurality of redundancy versions based on a scenario evaluation of a previous transmission associated with the set of information bits, and transmit, via the transmitting circuitry, a selected portion of the code word from the start position.
