摘要： A method performed by a WTRU may comprise receiving a common feedback transmission, in response to a transmission of the WTRU. The common feedback transmission may convey one or both of a preamble and a DMRS to indicate an identifier of the WTRU. The WTRU may determine whether a preamble-to-DMRS association is configured. If the preamble-to-DMRS association is not configured, the WTRU may determine to use both the preamble and the DMRS as the identifier of the WTRU. If the preamble-to-DMRS association is configured, the WTRU may determine whether to use one of the preamble or the DMRS as the identifier of the WTRU, based on the preamble-to-DMRS association.

摘要： A wireless transmit/receive unit (WTRU) may receive sounding reference signal (SRS) resource configuration information. The WTRU may also receive beam indication (ID) information and panel ID information in downlink control information (DCI) and determine a WTRU panel based on the panel ID information or the SRS resource configuration information. The WTRU may also determine uplink (UL) beam sweeping for each determined WTRU panel based on the beam ID using one or more sweeping parameters.

摘要： Methods and apparatus are disclosed for new radio (NR) vehicle-to-everything (V2X) communications. A transmitting wireless transmit/receive unit (WTRU) may generate and attach cyclic redundancy check (CRC) bits to sidelink data. The WTRU may low-density parity check (LDPC) encode and rate match the sidelink data and the CRC bits attached to the sidelink data. The WTRU may scramble the rate matched sidelink data with a data scrambling sequence, and the data scrambling sequence may be based on at least a source identifier (ID). Also, the WTRU may modulate the scrambled sidelink data to generate a sidelink data message, and then transmit the sidelink data message to a receiving WTRU. Also, the data scrambling sequence may be based on a data scrambling sequence initialization value, which value may include at least one of a full sidelink control information (SCI) CRC, a partial SCI CRC, a destination ID or a data scrambling constant.

摘要： Methods and apparatuses are described herein for Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) in a wireless transmit/receive unit (WTRU). A WTRU may determine a first resource associated with first transmission and a second resource associated with second transmission for uplink (UL) NOMA. The WTRU may generate control information including selection information of the second resource. The WTRU may transmit the control information using the UL NOMA on the first resource. The WTRU may then receive one or more indicators indicating whether the second transmission uses OMA or NOMA. The one or more indicators may comprise a discontinue NOMA transmission indicator (DTI) and a NOMA type transmission indicator (NMI). If the DTI indicates the OMA, the WTRU transmit data on the second resource using the OMA. If the DTI indicates the NOMA, the WTRU transmit, based on the NMI, data on the second resource using the UL NOMA.

摘要： A method (2200) and apparatus for transmitting data using low density parity check, LDPC, encoding and hybrid automatic repeat request-incremental redundancy, HARQ-IR, is disclosed. The method may comprise selecting (2206) a protograph sub-matrix from a family of protograph matrices based on one or more of an initial code rate, an information block size, a maximum retransmission count or a maximum number of redundancy versions, wherein the selected protograph sub-matrix supports HARQ-IR. A parity check matrix may be determined based on the selected protograph sub-matrix (2208). One or more data blocks may be encoded using LDPC based on the parity check matrix (2218) and the LDPC encoded data block may be transmitted (2220) to an LDPC HARQ-IR configured receiver.

摘要： Methods, apparatuses, systems, devices, and computer program products directed to adapting cyclic prefix (CP) duration to delay spread, e.g., CP adaptation with constant OFDM symbol duration, are provided. Pursuant to new methodologies and/or technologies provided herein, adaptive CP may be carried out, e.g., to enhance spectral efficiency. In an embodiment, a CP duration may be made proportional or otherwise adapted (collectively "adapted") to a delay spread without adjusting symbol duration. Adapting the CP duration may include adjusting a clocking rate of digital-to-analog conversion and/or a clocking rate of analog-to-digital conversion according to the CP duration. Alternatively, adapting the CP duration may include performing fractional sampling rate conversion.

摘要： Methods for sidelink synchronization may be used by a wireless transmit/receive unit (WTRU) that wants to a join a group of WTRUs, such as a vehicle platoon. The WTRU may receive configuration information for sidelink communications including measurement thresholds. The WTRU may monitor a sidelink channel for signals from synchronization sources. The WTRU may perform a sidelink measurements and determine synchronization source type and hop number for the synchronization sources. The WTRU may compile a list of synchronization sources with sidelink measurement above a first threshold and select a platoon leader type. If there is no platoon leader in the list, the WTRU may select the synchronization source with hop number below a hop threshold. Otherwise, the WTRU may select the synchronization source for which the value of the sidelink measurement is greater than a second sidelink measurement threshold. The WTRU may establish a link with the selected synchronization source.

摘要： Systems, methods, and instrumentalities may be provided for v2x synchronization. A WTRU may receive a first SLSS from a first WTRU and a second SLSS from a second WTRU. The WTRU may determine, based on the first and second SLSSs, a priority for each of the first and second WTRUs. The WTRU may determine a priority order that may include a first priority assigned to a platoon leader, a second priority assigned to a WTRU in-coverage by the platoon leader, and a third priority assigned to a WTRU out-of-coverage by the platoon leader. The first priority may be higher than the second priority which may be higher than the third priority. The WTRU may select, according to the priority order, a SyncRef WTRU from the first and second WTRUs. The selected SyncRef WTRU may have a highest priority in the priority order of the first and second WTRUs.

摘要： Methods and systems for paging monitoring, which may be performed by wireless transmit/receive unit (WTRU) that supports multi-beam communications, are disclosed herein. A WTRU may receive a configuration for enhanced paging. The WTRU may determine a first subcarrier spacing (SCS) for a synchronization signal block (SSB) and a second SCS for a paging reception. The WTRU may determine a paging multiplexing type (PMT) based on the first SCS and second SCS, where the PMT is of a first type if the first and second SCS are different and a second type if the first and second SCS are the same. The WTRU may determine a beam, time and frequency relationship among a paging control resource set (CORESET), a paging message, and/or the SSB based on the determined PMT. The WTRU may monitor a paging occasion (PO) in one or more beams based on the determined beam, time and frequency relationship.
