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: A method for a Wireless Transmit/Receive Unit (WTRU). The method including receiving from a network configuration information indicating multiple frequency layers for positioning reference signals; and at least one activated frequency layer from among the multiple frequency layers. The frequency layers may be associated with one or more carriers for data transmission, wherein the carrier is co-located with its associated frequency layer for positioning; and bandwidth parts (BWPs) within carriers for data transmission. The WTRU may receive from the network activation/deactivation information indicating activation/deactivation of any of a secondary cell (SCell) and a BWP. The WTRU may transmit information indicating, for example, a set of frequency layers used for positioning, wherein the set of frequency layers is enabled according to any of an accuracy requirement, a latency, a measured RSRP of one frequency layer, and a measured CSI-RS corresponding to BWPs being a threshold.

Abstract: A wireless transmit/receive unit (WTRU) may be configured for sidelink (SL) communication. The WTRU may receive SL discontinuous reception (DRX) configuration information from a peer SL WTRU. The SL DRX configuration information may comprise timer information. The timer information may comprise at least a SL on-duration timer, a SL inactivity timer, a SL hybrid automatic repeat request (HARQ) round trip time (RTT) timer, and a SL HARQ retransmission timer. The WTRU may apply the received SL DRX configuration information. The WTRU may report, on a condition that the WTRU has a connection to a network entity, to the network entity that the WTRU applied the received SL DRX configuration information.

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 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: Methods and apparatuses for joint channel state information (CSI) measurement are described herein. A method may include receiving channel state information reference signals (CSI-RSs) from first and second transmit/receive points (TRPs), determining CSI, and selecting one of the TRPs as a primary TRP and a remaining one of the first TRP or the second TRP as a secondary TRP. The method may include reporting information indicating a first CSI for the primary TRP and receiving second CSI-RSs from the TRPs. The method may include determining a second CSI and a precoding matrix indicator (PMI) for the primary TRP, and determining channel coding information for the primary TRP. The method may include determining a second CSI for the secondary TRP, determining, based on channel coding information and the second CSI for the secondary TRP and a PMI for the secondary TRP, and reporting information indicating the PMI for the second TRP.
