Abstract: A WTRU may be configured to perform logical channel prioritization. A WTRU may receive an indication (e.g., a mapping) that indicates an association between a first HARQ process ID and a first HARQ processing type and between a second HARQ process ID and a second HARQ processing type. The WTRU may receive an indication (e.g., a mapping) that indicates an association between a first logical channel and the first HARQ processing type and between a second logical channel and the second HARQ processing type. The WTRU may receive an a HARQ process ID indication. The WTRU may determine a HARQ processing type associated with the HARQ process ID. The WTRU may determine a logical channel available for a transmission. The logical channel available to be used may be determined based on the HARQ processing type associated with the HARQ process ID. The WTRU may send the transmission.

Abstract: Systems, methods, and instrumentalities are described herein for sidelink (SL) collision detection and indication (e.g., in new radio (NR) vehicular communications (V2X)). A wireless transmit/receive unit (WTRU) may send resource reservations (e.g., in sidelink control information (SCI)). A receiving (RX) WTRU may receive SCI from (e.g., multiple) transmitting (TX) WTRUs, where the TX WTRUs are reserving resources for transmission. The TX WTRUs may be unaware of the other TX WTRUs (e.g., unaware of the resources being reserved by other TX WTRUs). Resources may be in conflict, for example, if the reserved resources overlap (e.g., partially or completely). Collision may occur, for example, if multiple TX WTRUs reserve the resources in conflict for transmission and/or if the TX WTRUs reserving the resources in conflict for transmission do not reselect a non-conflicting resource.

Abstract: A wireless transmit/receive unit (WTRU) may perform a listen before talk (LBT) procedure associated with a sidelink (SL) bandwidth. The SL bandwidth may include a resource block (RB) set. The WTRU may determine a CSLF associated with the RB set of the SL bandwidth based on the LBT procedure. The WTRU may determine a resource for reporting the CSLF, for example, based on a priority rule. The priority rule may indicate that a licensed resource has a higher priority than an unlicensed resource. The priority rule may indicate that, if a consistent LBT failure is not detected on an unlicensed uplink (UL) resource, the unlicensed UL resource has a higher priority than an unlicensed SL resource. The WTRU may send a medium access control (MAC) control element (CE) using the determined resource. In examples, the MAC CE may indicate the RB set.

Abstract: Methods and apparatuses are described herein for sidelink communication in a wireless transmit/receive unit (WTRU). For example, a first WTRU configured with first and second resource pools may perform at least one congestion measurement of the second resource pool. The first resource pool may be configured for use by the first WTRU for transmission of the first data. The second resource pool may be configured for use by a second WTRU for transmission of the second data associated with a higher priority than the first data. If the at least one congestion measurement of the second resource pool is below a predetermined threshold, the first WTRU may transmit the first data using the first resource pool. If the at least one congestion measurement of the second resource pool is above a predetermined threshold, the first US may not transmit the first data using the first resource pool.

Abstract: Systems, methods, and instrumentalities are disclosed herein associated with positioning in wireless systems. Features may be implemented, for example, in the behavior of a wireless transmit/receive unit (WTRU) for measurement reporting during a multi-beam channel scan, in WTRU behavior during a measurement report in the presence of a multipath, and/or in WTRU behavior during reporting to acquire correction information from the network. A WTRU may receive a PRS transmission via multiple paths, wherein the paths may be associated with the beams. The WTRU may report Rx−Tx time differences associated with the reception of the PRS transmission via multiple paths and transmission of respective SRSp's associated with the respective paths.

Abstract: Systems, methods, and devices for sidelink transmit-receive distance related determinations are disclosed herein. In one example, a wireless transmit receive unit (WTRU) may be configured with an associate between range information and zone configuration. The WTRU receive an indication of a specific range information requirement and determine its own zone location based on the configured information and location means (e.g., GPS). The WTRU may also receive zone location information of a transmitting device, and determine the distance between the WTRU and the transmitting device.

Abstract: Systems, methods, and instrumentalities are described herein for enabling positioning, for example, in unlicensed spectrum. A wireless transmit/receive unit (WTRU) may monitor for reference signals (e.g., positioning reference signals) in the unlicensed spectrum. The WTRU may fallback to a different positioning configuration. For example, the WTRU may fallback to monitor for reference signals in the unlicensed spectrum within a discovery reference signal window. For example, the WTRU may fallback to monitor for reference signals in a licensed spectrum. The WTRU may determine to fallback to a different positioning configuration, for example, based on whether reference signals are determined to be missing (e.g., consecutive missing reference signals).
