  • Publication number: 20240340959
    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: 20240340764
    Abstract: Systems, methods, and instrumentalities are described herein related to radio-link failure (RLF) and recovery for multihop and multiconnectivity relays. A wireless transmit/receive unit (WTRU) may act as a relay to another WTRU (e.g., a remote WTRU). For example, a first WTRU may act as a relay WTRU (e.g., a WTRU to network relay) towards a second WTRU (e.g., a remote WTRU). The first WTRU may provide information associated with cell reselection and/or re-establishment to the second WTRU (e.g., if the first WTRU experiences a radio-link failure).

  • Patent number: 12114196
    Abstract: A method for a Wireless Transmit/Receive Unit (WTRU). The method including receiving from a network configuration information indicating multiple frequency layers for positioning reference signals; and at least one activated frequency layer from among the multiple frequency layers. The frequency layers may be associated with one or more carriers for data transmission, wherein the carrier is co-located with its associated frequency layer for positioning; and bandwidth parts (BWPs) within carriers for data transmission. The WTRU may receive from the network activation/deactivation information indicating activation/deactivation of any of a secondary cell (SCell) and a BWP. The WTRU may transmit information indicating, for example, a set of frequency layers used for positioning, wherein the set of frequency layers is enabled according to any of an accuracy requirement, a latency, a measured RSRP of one frequency layer, and a measured CSI-RS corresponding to BWPs being a threshold.

  • Publication number: 20240334503
    Abstract: A method performed by a relay wireless transmit/receive unit (WTRU) includes receiving an indication of a change in state of a remote WTRU having a paging link with the relay WTRU, receiving a paging message from a network. The paging message includes a system information (SI) change indication, wherein the SI change indication indicates an availability of updated SI information from the network for the remote WTRU. The relay WTRU transmits the updated SI information to the remote WTRU based on the received indication of a change in state of the remote WTRU.

  • Publication number: 20240314605
    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)).

  • Patent number: 12088414
    Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.

  • Publication number: 20240298350
    Abstract: A wireless transmit/receive unit (WTRU) may perform a listen before talk (LBT) procedure associated with a sidelink (SL) bandwidth. The SL bandwidth may include a resource block (RB) set. The WTRU may determine a CSLF associated with the RB set of the SL bandwidth based on the LBT procedure. The WTRU may determine a resource for reporting the CSLF, for example, based on a priority rule. The priority rule may indicate that a licensed resource has a higher priority than an unlicensed resource. The priority rule may indicate that, if a consistent LBT failure is not detected on an unlicensed uplink (UL) resource, the unlicensed UL resource has a higher priority than an unlicensed SL resource. The WTRU may send a medium access control (MAC) control element (CE) using the determined resource. In examples, the MAC CE may indicate the RB set.

  • Publication number: 20240292329
    Abstract: A first wireless transmit/receive unit (WTRU) may receive, from a second WTRU, sidelink control information (SCI), including first information indicating if a resource is reserved by the second WTRU, and second information indicating if the second WTRU is a power saving or non-power saving. The first WTRU may measure a reference signal receive power (RSRP) of signals transmitted by the second WTRU. The first WTRU may add a resource to a set of available resources if the first information indicates that the resource is not reserved by the second WTRU. If a resource is reserved, the WTRU may set an RSRP threshold to a first set or second threshold based on a power saving mode of the second WTRU. The first WTRU may add the resource to the set of available resources if the measured RSRP is less than the selected RSRP threshold.
