Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed to selection and/or reselection of WTRUs and paths are provided. Among such methods is a method that may be implemented in a first WTRU and may include determining first measurements based on first sidelink transmissions received from a second WTRU; receiving, from the second WTRU, second measurements associated with a path between the first WTRU and a third WTRU, wherein second measurements are based, at least in part, on sidelink transmissions exchanged between the third WTRU and the second WTRU or between the third WTRU and a fourth WTRU; determining a measurement of the path based on any of the first and second measurements; determining transmission parameters for transmitting discovery messages during a communication period based on any of the measurement of the path and quality of service criteria; and transmitting the discovery messages according to the transmission parameters.

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: The disclosure pertains to methods and apparatus using V2X enhancements to perform discontinuous reception. In an embodiment, a method implemented by a first WTRU, for a device-to-device (D2D) communication between the first WTRU and a second WTRU, the method may include any of comprising receiving, from the second WTRU, D2D control information comprising: (1) first information indicating one or more first transmission resources reserved for transmission of the D2D communication and (2) second information indicating if at least one second transmission resource is reserved for retransmission of the D2D communication; determining a sleeping period for the first WTRU that ends prior to a reception time of the retransmission of the D2D communication, wherein the sleeping period is based on the second information; and receiving the retransmission of the D2D communication, after an end of the determined sleeping period.

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.

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: The disclosure pertains to methods and apparatus for network energy savings. A method may be implemented in a wireless transmit/receive unit (WTRU). The method may include receiving configuration information indicating a pattern of time periods during which a cell is available or unavailable and receiving a downlink control information (DCI) comprising an indication associated with an availability of the cell. The method may include determining that a resource may be included in a time period during which the cell may be determined by the WTRU to be available based on the indicated pattern of time periods and the indication. The method may include transmitting or receiving in the resource based on the resource being included in the time period during which the cell may be available.

Abstract: One or more method/devices/systems are disclosed herein that address problems that arise out of sending feedback in sidelink and/or between devices operating in unlicensed spectrum. For example, in some cases, a first device may need to send a transmission to a second device. The first device may be configured with information such that the first device can determine the necessary parameters to send the transmission using the configured information. In an example, the second (receiving) device may determine to provide feedback for a received transmission.
