Abstract: Methods, systems, and apparatuses for sidelink communication are disclosed. A WTRU may receive a first SCI element from a second WTRU within a group. The WTRU may receive a first RCI element within a first set of resources scheduled by the first SCI. The first RCI may include information about which WTRU in the group is scheduled to use a second set of resources. The WTRU may determine, based on the first RCI, that one or more subresources within the second set of resources are available. The WTRU may transmit data in the one or more subresources. The first SCI and the first RCI may be received in a first reservation period and the one or more subresources may be in a second reservation period.

Abstract: V2X Enhancements to support V2P communication are disclosed. In particular, Vehicle to Pedestrian Communications are provided. Methods and apparatus for operation by an initiating wireless transmit/receive unit (WTRU) for direct link with a peer WTRU using a first key identifier of a root key are provided. In one embodiment, a method includes sending, by the initiating WTRU to the peer WTRU, a release request message to release the direct link with the peer WTRU, the release request message including information indicating first security information associated with a second key identifier of the root key. The method further includes receiving, receiving, by the initiating WTRU from the peer WTRU, a response to the release request message including second security information associated with the second key identifier of the root key. The method also includes determining, by the initiating WTRU, the second key identifier of the root key using the first security information and the second security information; and sending, by the initiating WTRU to the peer WTRU, a message including information indicating the second key identifier of the root key.

Abstract: Methods and apparatuses are described herein for dynamic PC5 communication adaptation. For example, a UE may receive, from a vehicle-to-everything control function (V2X CF) or a vehicle-to-everything application server (V2X AS), a V2X provisioning message that includes a first transmission profile and determine, based on the first transmission profile, a first range to configure PC5 communication of a plurality of UEs associated with the V2X platoon. When a number of UEs joining the V2X platoon exceeds a certain threshold, the UE may transmit, to the V2X CF or the V2X AS, a modification request message requesting a second transmission profile. The UE may receive, from the V2X CF or the V2X AS, a modification response message that includes the second transmission profile and determine, based on the second transmission profile, a second range to reconfigure the PC5 communication of the plurality of UEs associated with the V2X platoon.

Abstract: Methods and apparatuses are described herein for proximity-based services (ProSe) service-based discovery. For example, a service utilizing-wireless transmit/receive unit (SU-WTRU) may be provisioned with a type of discovery on a per-service basis and a security credential on a per-service basis. The SU-WTRU may transmit (315) a PC5 discovery message with the type of discovery and a first security element that is generated based on the security credential. The WTRU may then receive (325), from a service providing-wireless transmit/receive unit (SP-WTRU), a PC5 discovery response message that includes a second security element and a service identity associated with a service that the SP-WTRU provides. On a condition that the second security element is verified based on the provisioned security credential, the SU-WTRU may authorize (330) the SP-WTRU to establish a PC5 communication link with the SP-WTRU.

Abstract: Methods, apparatus, systems, architectures and interfaces, performed by a relay wireless transmit/receive unit (R-WTRU) including a transmitter, a receiver, a memory, and a processor, for establishing extended unicast links and management unicast links are provided. The method includes: performing, by the R-WTRU, a link establishment procedure for establishing any number of extended unicast links for relaying traffic between a service-provider WTRU (SP-WTRU) and any number of service-user WTRUs (SU-WTRUs) according to a mapping generated by the R-WTRU, the link establishment procedure including: (1) generating a mapping of any of the extended links and layer 2 (L2) identifiers (IDs) for any of a SP-WTRU, a R-WTRU, and any number of SU-WTRUs, and (2) transmitting a unique relay ID; establishing a management unicast link for the extended unicast links; and applying any number of link management requests received via the management unicast link to associated extended unicast links.

Abstract: Mobile device-to-mobile device discovery may be performed via a relay device (e.g., wireless transmit and receive unit (WTRU)), which may send a discovery request (e.g., including service ID, relay capability indication, and relay WTRU ID) to a ProSe server. A discovery response may include a (e.g., ProSe) relay service broadcast code and discovery filter (e.g., corresponding to service ID for a service broadcast by a service provider WTRU). The relay WTRU may use the discovery filter to listen for a ProSe code broadcast by a service provider WTRU. The relay WTRU may determine a received ProSe code matches the discovery filter. The relay WTRU may broadcast the relay service broadcast code based on the match. The service broadcast code broadcast may be intended for receipt by a service utilizing WTRU, which may utilize the relay WTRU to join/receive a service from a service provider WTRU.

Abstract: Method, apparatus and systems are disclosed that may be implemented in a Wireless Transmit/Receive Unit (WTRU) for unicast communication with another WTRU. The method may include sending, by the WTRU to the other WTRU via a PC5 interface, a communication request indicating first security information for the WTRU and receiving, by the WTRU from the other WTRU via the PC5 interface, information which is integrity protected indicating second security information for the other WTRU. The method may also include deriving, by the WTRU from the indicated second security information, a first set of security keys for communication via a first layer using the U-plane and a second set of security keys for communication via a second layer using the C-plane; and sending, by the WTRU to the other WTRU via the PC5 interface, a message that is at least integrity protected using the derived first set of keys.

Abstract: Systems, methods, and instrumentalities are provided for vehicle to everything (V2X) service oriented link establishment. A first wireless transmit receive unit (WTRU) may broadcast a direct communication request message. The direct communication request message may include a first security context identifier (ID). The first WTRU may receive a direct security mode command message from a second WTRU. The direct security mode command message may include a second security context ID. The first may determine a third security context ID by combining the first security context ID and the second security context ID. The first WTRU may establish, using the third security context ID, a secure direct communication link with the second WTRU. The first WTRU may generate, based on the third security context ID, a security context entry for the secure direct communication link with the second WTRU.
