Abstract: A method of wireless communication of a UE is provided. The UE determines resources of a first PDSCH and resources of second at least one PDSCH on a cell, the first PDSCH being a unicast PDSCH specific to the UE. The UE determines that the first PDSCH overlaps with the second at least one PDSCH in a time domain. The UE determines whether the second at least one PDSCH is another unicast PDSCH specific to the UE. When the second at least one PDSCH is not another unicast PDSCH specific to the UE, a duration required for decoding the first PDSCH meets a duration threshold, and the cell is in a first frequency range, the UE (a) refrains from decoding the first PDSCH independently of a transport block size of the second at least one PDSCH or (b) determines a transport block size of the second at least one PDSCH.

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: 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.

Abstract: An apparatus determines a code block size (CBS) of information bits contained in a codeword of low-density parity check (LDPC) coding. The apparatus compares the CBS with at least one threshold, determines, based on a result of the comparison, a Kb number and determines a Kp number based on a code rate and the Kb number. The apparatus generates a parity check matrix. An information portion of the parity check matrix is a first matrix formed by M number of second square matrices. M is equal to Kp multiplied by Kb. A total number of columns in the Kb number of second square matrices is equal to a total number of bits of the CBS. One or more matrices of the M number of second square matrices are circular permutation matrices. The apparatus operates an LDPC encoder or an LDPC decoder based on the parity check matrix.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, on a down-link, an indication indicating a first number of predetermined time units for delaying sending an acknowledgment message after receiving data in a slot. The UE obtains one or more conditions based on the first number, the one or more conditions affecting time required for processing the data received in the slot and affecting a duration of a predetermined time unit. The UE determines whether at least one of the one or more conditions is met. The UE further sends, on an uplink, the acknowledgment message according to the first number predetermined time units after receiving the data in the slot when at least one of the one or more conditions is met.
