  • Publication number: 20250151085
    Abstract: Systems, methods, and instrumentalities are described herein for sidelink (SL) collision detection and indication (e.g., in new radio (NR) vehicular communications (V2X)). A wireless transmit/receive unit (WTRU) may send resource reservations (e.g., in sidelink control information (SCI)). A receiving (RX) WTRU may receive SCI from (e.g., multiple) transmitting (TX) WTRUs, where the TX WTRUs are reserving resources for transmission. The TX WTRUs may be unaware of the other TX WTRUs (e.g., unaware of the resources being reserved by other TX WTRUs). Resources may be in conflict, for example, if the reserved resources overlap (e.g., partially or completely). Collision may occur, for example, if multiple TX WTRUs reserve the resources in conflict for transmission and/or if the TX WTRUs reserving the resources in conflict for transmission do not reselect a non-conflicting resource.

  • Publication number: 20250142292
    Abstract: A wireless transmit/receive unit, WTRU, receives a positioning request message from another WTRU (1402). The positioning request message indicates a request associated with one or more of a sidelink positioning reference signals, SL-PRS, transmission or a SL-PRS reception and indicates a range of one or more parameters associated with the SL-PRS transmission or reception; these parameters comprise one or more of SL-RSRP, angle of departure AoD, angle of arrival AoA, and a line of sight LOS/NLOS metric. The WTRU measures the one or more parameters indicated in the positioning request message (1404) and performs the SL-PRS transmission (1410) or the SL-PRS reception (1410) on the condition that the measured parameters are within the range indicated in the positioning request message (1408).

  • Publication number: 20250142595
    Abstract: There may be approaches for sidelink unlicensed (SL U) channel access in Mode 2. For example, a wireless transmit receive unit (WTRU) may perform SL U channel access and resource selection for channel occupancy time (COT) sharing and COT initiation within a resource selection window (RSW). The WTRU may detect COT and share based on control information, such as remaining duration, the number of scheduled transmission(s) within the COT, frequency resource assignment, priority, cast type, WTRU source and/or destination ID, COT/resource reservation, channel congestion, etc. The WTRU may determine SL COT initiation based on LBT and SCI sensing information including COT/resource reservation, priority, cast type, WTRU source and/or destination ID, channel congestion, etc. The WTRU may determine transmission resources within shared and initiated SL COT based on WTRU source and/or destination ID of a TB to transmit, RB interlace assignment indicated in decoded SCI associated with an overlapping reserved COT.

  • Publication number: 20250142624
    Abstract: Devices, methods, and systems for coverage extension. A bundle of repeated transmissions of a preamble are transmitted responsive to a reference signal received power (RSRP) being less than a threshold and a random access (RA) procedure being initiated. A random access response (RAR) window is monitored for a random access radio network temporary identity (RA-RNTI) corresponding to the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble is transmitted based on a spatial filter that is different from others of the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble comprises a preamble index that is different from preamble indices of others of the repeated transmissions of the preamble. In some implementations, the spatial filter comprises a transmission (Tx) beam. In some implementations, the bundle of repeated transmissions of the preamble comprises retransmissions of a msg1.

  • Publication number: 20250142516
    Abstract: A WTRU may be configured to perform adaptive on-demand positioning. The WTRU may receive configuration information for receiving positioning signals (PRSs) from a first set of one or more TRPs. For example, the configuration information may comprise PRS configuration information associated with each of the first set of TRPs. The WTRU may determine a metric (e.g., a weight, rank, etc.) associated with TRP that is not included in the first set of one or more TRPs. For example, the metric may be determined (e.g., using an AI/ML model) based on: a location associated with the TRP, a location associated with the WTRU, and/or a measurement associated with the TRP. The WTRU may send a PRS activation request to activate PRS from the TRP. For example, the PRS activation request may indicate the PRS configuration that the WTRU requests be activated, and a metric associated with that PRS configuration.

  • Publication number: 20250126535
    Abstract: A wireless transmit/receive unit (WTRU) may comprise a processor. The processor may be configured to receive (e.g., via broadcast) configuration information indicating a time that a same-PCI satellite switch may occur. In one or more examples, the WTRU may transmit assistance information prior to the same-PCI satellite switch. The assistance information may, for example, include a re-synchronization duration, capabilities to synchronization procedures, and/or a time indication for resuming TX and/or RX. The WTRU may receive configuration information for satellite re-synchronization. The WTRU may perform the same-PCI satellite switch to the second satellite, for example, based on the configuration information indicating the time for the same-PCI satellite switch. In performing the same-PCI satellite switch, the WTRU may start a resynchronization gap, suspend UL TX and/or DL RX, and/or perform re-synchronization procedure(s).

  • Patent number: 12279140
    Abstract: Power efficient measurements may be implemented for high frequency operations. A WTRU may determine measurement occasions, DRX cycle/configuration transitions, DRX pause/resume, DRX timer operation, and/or BFR based on scheduling activity, beam configuration, BFI detection, BFD, beam loss, etc. A WTRU may be configured with multiple DRX cycles and measurement opportunities (e.g., with different periodicities). The WTRU may perform (e.g., RS) measurement(s) with determined/configured timing (e.g., DRX on-durations) in a first DRX cycle based on condition(s). The WTRU may switch to a second DRX cycle and perform RS measurement(s) with determined/configured timing based on condition(s) (e.g., counted number of BFIs detected in first DRX cycle). The WTRU may switch from the second (e.g., short) DRX cycle to the first (e.g., long) DRX cycle or to non-DRX operation (e.g., DRX suspension or reset DRX inactivity timer) based on condition(s) (e.g., number of BFIs in first and/or second DRX cycle(s)).
