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: A first wireless transmit/receive unit (WTRU) may receive, from a second WTRU, sidelink control information (SCI), including first information indicating if a resource is reserved by the second WTRU, and second information indicating if the second WTRU is a power saving or non-power saving. The first WTRU may measure a reference signal receive power (RSRP) of signals transmitted by the second WTRU. The first WTRU may add a resource to a set of available resources if the first information indicates that the resource is not reserved by the second WTRU. If a resource is reserved, the WTRU may set an RSRP threshold to a first set or second threshold based on a power saving mode of the second WTRU. The first WTRU may add the resource to the set of available resources if the measured RSRP is less than the selected RSRP threshold.

Abstract: Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

Abstract: Systems, methods, and instrumentalities are described herein related to radio-link failure (RLF) and recovery for multihop and multiconnectivity relays. A wireless transmit/receive unit (WTRU) may act as a relay to another WTRU (e.g., a remote WTRU). For example, a first WTRU may act as a relay WTRU (e.g., a WTRU to network relay) towards a second WTRU (e.g., a remote WTRU). The first WTRU may provide information associated with cell reselection and/or re-establishment to the second WTRU (e.g., if the first WTRU experiences a radio-link failure).

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: 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) and a method are described herein regarding preservation of positioning integrity associated with wireless systems. Using multiple positioning configurations and/or schemes (e.g., positioning reference signal (PRS) configurations/schemes), e.g., based on a switching pattern, may ensure integrity (e.g., adequate and/or robust integrity), for example, if error events (e.g., low reference signal received power, blockage of PRS from transmission/reception points (TRPs), etc.) have a persistent duration. The WTRU comprises a processor configured to receive a first, a second and a third subset of PRS configuration information, receive configuration information indicating error source information, a first switching pattern, and a positioning uncertainty threshold, perform a first set of measurements using the first switching pattern and the first and second subsets of PRS configuration information, determine a first positioning uncertainty based on the first set of measurements and the error source information, and send an indication indicating measurement information and positioning uncertainty information.
