Abstract: There may be one or more systems, methods, and/or devices that address a relay wireless communication scenario. For example, in such a scenario, there may be at least three entities, a remote a wireless transmit receive unit (WTRU) may need to communicate with a network node (e.g., gNB) and/or another WTRU that it cannot directly communicate with. This remote WTRU may communicate with a relay WTRU in order to communicate with the ultimate destination (e.g., another WTRU or a network node). The use of a relay may require establishment and configuration of one or more entities involved.

Abstract: Methods and apparatuses for link management and recovery for sidelink relays are described herein. Methods may include transmitting packets to a network via a first relay and using a sidelink radio bearer (SLRB) configuration, wherein the transmitted packets include an identifier associated with the first relay: receiving a message identifying alternate relay; and detecting radio link failure. Methods may include obtaining signal quality measurements of reference signals associated with the alternate relay: selecting, from the alternate relay, a second relay having the highest signal quality; and transmitting, to the selected second relay, a reconfiguration message indicating to use the same SLRB configuration or an equivalent SLRB configuration. If a response indicates that reconfiguration of the second relay is successful, a packet may be transmitted via the second relay using the same or equivalent SLRB configuration. The packet may include an identifier associated with the second relay.

Abstract: Systems, methods, and instrumentalities are described herein associated with relay usage (e.g., new radio (NR) relays used as an example herein) where handovers between sidelink (SL) and direct link and/or between sidelinks may be based on consideration of end-to-end radio and/or load conditions. Handover decisions may be determined, for example, based on measurements of direct connections, sidelink connections, and/or backhaul connections. Handover decisions may be optimized, for example, based on measurement reporting behavior. A remote wireless transmit/receive unit (WTRU) (e.g., a WTRU that may be configured to connect to a network, for example, using a relay WTRU) in sidelink relay operation with a relay WTRU may determine measurement reporting behavior (e.g., associated with performed measurements of the direct connections, sideline connections, and/or backhaul connections), for example, while considering the sidelink quality associated with the relay WTRU.

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: Method, apparatus, and systems for determining and transmitting positioning information in a wireless communication network are provided. For example, a method for wireless communications comprises receiving configuration information related to a set of positioning configurations and a small data transmission (SDT), determining, based on the configuration information, that at least one positioning configuration of the set of positioning configurations satisfies a positioning requirement and is associated with a payload size being less than a data volume threshold (DVT) associated with the SDT, selecting, from the at least one positioning configuration, positioning configuration associated with a payload size being closest to the DVT, performing a positioning measurement based on the selected positioning configuration, and sending, using an uplink resource for the SDT, a measurement report based on the selected positioning configuration and the positioning measurement.

Abstract: Systems and methods are described for QoS procedures supporting verticals in wireless systems. Data flows may combine or remap for QoS remapping conditions or state transitions. Data flow remapping may be indicated by triggering a B SR/SR or by multiplexing in the PDU. A non-default set of LCP parameters may be applied for an LCH after a QoS state transition, QoS remapping trigger, or LCP parameter suspension/override. A WTRU may operate according to a QoS adaptation state corresponding to a set of parameter values for a group of data flows, radio bearers, and/or logical channels. A WTRU may transition between QoS adaptation states. An RRC configuration and/or a MAC function may adapt to changing QoS requirement(s). QoS requirement(s) may adapt to changing MAC functions. QoS may be associated with survival time(s). QoS may adapt to higher layer indications. Packet forwarding may adapt to QFI in DL for QoS state changes.

Abstract: Methods and apparatus for uplink DRX and sidelink DRX are disclosed. A WTRU may receive a configuration of a hybrid automatic repeat request (HARQ) round trip time (RTT) timer. The WTRU may start the HARQ RTT timer in response to an event. The event may comprise receiving a downlink control information (DCI) that schedules a sidelink transmission. The event may comprise transmission of a sidelink control information (SCI) for the sidelink HARQ process. The event may comprise receiving HARQ feedback for a sidelink transmission. The event my comprise a pre-configured time period following a physical sidelink feedback channel (PSFCH) resource for feedback associated with a HARQ transmission. The WTRU may determine a value of a timer based on a sidelink transmission property or a sidelink transmission time.
