Abstract: Methods, apparatus, systems, architectures, and interfaces for a wireless transmit receive unit (WTRU) performing sidelink communications are provided. A method may include any of: receiving SL transmission configuration information indicating: (1) a dedicated resource allocation for assistance transmissions, and (2) triggering conditions for performing an assistance transmission; on condition that: (i) a physical SL shared channel (PSSCH) transmission is received, by the WTRU from another WTRU, according to a semi-persistent reservation, and (ii) one or more of the triggering conditions for performing the assistance transmission has occurred: (a) performing sensing based on sensing parameters associated with the received PSSCH transmission, and (b) selecting a dedicated resource allocation according to a resource of the received PSSCH transmission; and transmitting, to any number of proximate WTRUs, an assistance transmission using the selected dedicated resource allocation, the assistance transmission including assistance information associated with the sensing performed by the WTRU.

Abstract: A method for use in a Wireless Transmit/Receive Unit (WTRU). The method comprises: receiving, using an active receiver, system information comprising a first system information set, wherein the first system information set is currently valid for the WTRU; storing the system information; deactivating the active receiver and activating a passive receiver; determining whether a difference between a first parameter in the BSSI and a first parameter in the first system information set is greater than a threshold value, wherein on a condition that the difference is greater than the threshold value, reactivating the active receiver to receive a second system information set as a currently valid system information set for the WTRU.

Abstract: Systems, methods, and devices for collaborative positioning. A wireless transmit/receive unit (WTRU) is configured to perform and report positioning measurements including SL collaborative measurements. The WTRU serving as an anchor WTRU may select a set of member WTRUs for distributing the PRS measurement configurations based on the inter-WTRU distance measured over a SL. The selected subset of member WTRUs each provide measurement report to the anchor WTRU. The anchor WTRU reports to the LMF the measurements received from the member WTRUs and the associated SL distance measurements.

Abstract: Methods and apparatus are described for configuring desired network capabilities in a service-based network, including a method for a UE to initiate a network capability based registration to configure its desired network capabilities, a method for UEs to initiate a network capability based registration update when UEs are already registered to the network and want to dynamically re-configure their network capabilities, and a method for a network capability based UE configuration update, which allows NFs or ASs to initiate updating the network capabilities in a network slice for the UE.

Abstract: A wireless transmit/receive unit (WTRU) may receive a first higher layer configuration for a cancellation indication (CI). Further, the first higher layer configuration may include a set of reference frequency resources. Also, the WTRU may receive a grant indicating a frequency allocation and a time allocation for a scheduled transmission. Further, on a condition that the CI is received, the WTRU may interrupt the scheduled transmission. Additionally, the CI may indicate a subset of frequency resources of the set of reference frequency resources for each of a set of time symbols. Also, the WTRU may cancel the scheduled transmission on a condition that the subset of frequency resources of a set of time symbols overlaps with the frequency allocation and the time allocation for the scheduled transmission. In a further example, the first higher layer configuration may include an applicable maximum priority and the grant may include a priority index.

Abstract: A Sidelink AS group management function is disclosed for a UE to discover group members and organize them into AS layer sub-groups based on the AS layer group context information. A centralized Sidelink AS group management is disclosed that the Sidelink AS Group Manager discovers group members and organizes them into AS layer sub-groups for a UE. A Subgroup formation and configuration procedure is disclosed that SL AS Group Manager organizes the ULG into AS layer sub-groups, configures UE-to-UE relays for each UE in the ULG and sends the AS group management information to the UE. A distributed Sidelink AS group management method is disclosed that each UE discovers its group members and organizes the ULG into AS layer sub-groups. New Layer 2 structures and procedures are disclosed to enhance bearer management for Sidelink groupcast communications.

Abstract: A WTRU may receive a plurality of monitoring configurations. The plurality of monitoring configurations may be associated with a plurality of sub-bands. The WTRU may apply a monitoring configuration based on the location of a slot inside or outside of a COT. For example, the WTRU may apply (e.g., use) a first monitoring configuration outside a COT. The WTRU may apply a second monitoring configuration in a first slot of a COT. The WTRU may apply a third monitoring configuration to the slots of a COT subsequent to the first slot of the COT. The WTRU may switch back to the first monitoring configuration on a condition that the COT ends.

Abstract: Methods and apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.

Abstract: Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.

Abstract: A wireless transmit/receive unit (WTRU) may monitor a common physical downlink control channel (PDCCH) search space for a downlink control information (DCI) signal and a first radio network terminal identifier (RNTI). In an example, the DCI signal may include an uplink (UL)/downlink (DL) configuration indication. In a further example, the first RNTI may be associated with UL/DL configuration information. The WTRU may transmit UL data or receive DL data based on the received UL/DL configuration indication. In another example, the DCI may include a plurality of UL/DL configuration indications. In an additional example, a plurality of WTRUs may monitor the common PDCCH search space for the first RNTI. Also, the UL/DL configuration indication may indicate UL/DL configuration information on a symbol basis. Further, the WTRU may receive a second RNTI which is associated with the UL/DL configuration indication.
