    Abstract: Method and WTRU enabled for service continuity using WTRU-to-WTRU relays. A relay path may be modeled as an SLRB, RLC leg of an SLRB, and/or a MAC logical channel. The WTRU adds a path for a destination based on configured/usable relays. The WTRU may associate an end-to-end L2 destination ID with one or more path L2 destination IDs or path IDs. Upper layers select one or more paths for transmission of a packet/bearer. The WTRU may send a relay announcement message containing path connectivity information. A WTRU may select a path for transmission based on properties associated with a sidelink. The WTRU may activate/deactivate an SL bearer, unicast link, L2 destination, and/or RLC Leg. The WTRU changes a bearer associated with an SLRB from an established RLC entity to another established RLC entity.

    Abstract: A method for achieving an end-to-end quality of service (QoS) performed by a wireless transmit/receive unit (WTRU) may include receiving a protocol data unit (PDU) and an excess time indication from a source WTRU, and determining an expected latency for a next hop link based on a measure of channel load. It may also include dynamically determining a next hop latency budget based on the received excess time indication and the expected latency and determining resources for transmitting the received PDU based on the determined next hop latency budget. If the resources are available, the received PDU may be transmitted on the next hop using the determined resources.

    Abstract: Systems, methods, and instrumentalities are described herein that may be associated with new radio (NR) vehicular communication (V2X) sidelink power saving for unicast and groupcast. A first wireless transmit/receive unit (WTRU) may receive a message. The message may indicate a set of configuration groups and/or one or more suitability selection parameters. The WTRU may receive, from a second WTRU, a first indication. The first indication may indicate that the second WTRU is associated with a first configuration group and a first priority group. The first WTRU may receive, from a third WTRU, a second indication. The second indication may indicate that the third WTRU is associated with a second configuration group and a second priority value. The first WTRU may select a configuration group from the set of configuration groups based on the first indication and the second indication.

    Abstract: A WTRU may be configured to perform logical channel prioritization. A WTRU may receive an indication (e.g., a mapping) that indicates an association between a first HARQ process ID and a first HARQ processing type and between a second HARQ process ID and a second HARQ processing type. The WTRU may receive an indication (e.g., a mapping) that indicates an association between a first logical channel and the first HARQ processing type and between a second logical channel and the second HARQ processing type. The WTRU may receive an a HARQ process ID indication. The WTRU may determine a HARQ processing type associated with the HARQ process ID. The WTRU may determine a logical channel available for a transmission. The logical channel available to be used may be determined based on the HARQ processing type associated with the HARQ process ID. The WTRU may send the transmission.

    Abstract: Systems, methods, and devices for enabling simultaneous transmission of different types of transmission protocols. A device such as a wireless transmit receive unit (WTRU) may receive configuration information and receive a data packet from an upper layer of a protocol stack operating on the WTRU. The WTRU may then determine a transmission type for the data packet at a first time based on the configuration information and a condition. The WTRU may then transmit the data packet using the determined transmission type. The configuration information may include decision criteria associated with determining the transmission type and a set of logical channels that are associated with data properties. The transmission type may be one of a network scheduled mode, WTRU autonomously scheduled mode, LTE, NR, unicast, groupcast, or broadcast.

    Abstract: A wireless transmit/receive unit (WTRU) operating in an autonomous-scheduled mode may select a first resource from a resource pool. The WTRU may determine that the first resource is reserved for at least one sidelink transmission scheduled via a network-scheduled mode. The WTRU may evaluate the availability of resources in the resource pool based on determining that the first resource is reserved for the sidelink transmission. The WTRU may determine that a resource is available based on a measurement comparison to one or more thresholds. For example, there may be a first threshold for resources reserved by WTRUs operating using the network-scheduled mode and a second threshold for resources reserved by WTRUs operating using the autonomous-scheduled mode. The first threshold may be determined based on the second threshold and an offset value. The WTRU may reselect to a second resource in the resource pool based on the evaluated resource availability.
