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 herein for supporting low power high accuracy positioning (LPHAP). A wireless transmit/receive unit (WTRU) may receive configuration information (e.g., in a radio resource control (RRC) reconfiguration message) from a first cell. The configuration information may indicate a first sounding reference for positioning (SRSp) configuration and a second SRSp configuration. The first SRSp configuration may be associated with a first positioning area and the second SRSp configuration may be associated with a second positioning area. The first positioning area may include a first cell ID set and the second positioning area may include a second cell ID set. The first SRSp configuration may be activated and the second SRSp configuration may be deactivated.

Abstract: Methods and apparatuses are described herein for monitoring radio links between wireless transmit/receive units (WTRUs) and determining of radio link failure, and may be used, among others, for New Radio (NR) vehicular communication (V2X); a mode whereby WTRUs can communicate with each other directly. A radio link between a WTRU and another WTRU may be monitored independently per ongoing unicast and/or multicast link, and radio link failure (RLF) may be determined as a function of the monitoring.

Abstract: A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

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 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: Systems, methods, and instrumentalities are described herein for sidelink discovery, for example, associated with relays, e.g., NR relays. Discovery data may be transmitted, for example, to initialize communication between devices. Discovery data may be transmitted alone or multiplexed with other data (e.g., sidelink data). Discovery data with a high priority may be transmitted alone. Discovery data with a low priority may be multiplexed with other data (e.g., other data received within a duration of time). Discovery data may be multiplexed with other data that share the same destination identity. Resource allocation may be performed, for example, based on whether the discovery data is transmitted alone or multiplexed with other data.
