Abstract: Various examples and schemes pertaining to shared negative acknowledgement (NACK) for groupcast and multicast in New Radio (NR) vehicle-to-everything (V2X) communications are described. An apparatus as a source user equipment (UE) transmits data to two or more destination UEs of a plurality of destination UEs via groupcast or multicast with hybrid automatic repeat request (HARQ). The apparatus then receives a NACK on a single time-frequency resource from at least one of the two or more destination UEs. The single time-frequency resource is shared by the plurality of destination UEs to transmit the NACK to the source UE.

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: A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.
