Abstract: An apparatus may be configured to determine whether to prioritize a sidelink (SL) logical channel group (LCG) based on an SL prioritization threshold and a UL prioritization threshold, on a condition that a UL prioritization threshold is configured. The apparatus may be configured to determine whether a prioritization value associated with the SL LCG is lower than the SL prioritization threshold. The apparatus may be configured to determine (e.g., at least) whether an uplink (UL) LCG has a prioritization value that is equal to or higher than the UL prioritization threshold. The apparatus may be configured to determine whether to prioritize SL buffer status reporting (BSR) based on a size of a UL grant and the determination of whether to prioritize the SL LCG. The apparatus may be configured to report a buffer status based on the determination of whether to prioritize the SL BSR.

Abstract: Methods, apparatus, systems, architectures and interfaces for determining whether sidelink resources of a sidelink radio bearer are available, and for reserving resources of any number of sidelink radio bearers for transmission of periodic data are provided. The method includes determining any of a size, a period, or a pattern of a resource reservation for periodic data that is to be transmitted by the WTRU via the sidelink radio bearer; determining sidelink resources available for transmission of the periodic data via any number of sidelink radio bearers; and transmitting a message including the resource reservation including information indicating reservation of the available sidelink resources for transmission of the periodic data by the WTRU according to any of the size, the period, or the pattern of a resource reservation, wherein the message includes any of a bearer identifier (ID) or Quality of Service (QoS) information.

Abstract: Methods, apparatuses, systems, etc. for, and/or for use in connection with, performing network access and/or other procedures in a non-terrestrial network (NTN) of a communications system. Among the methods are methods that may be implemented in a wireless transmit/receive unit (WTRU) and may include any of receiving, from the NTN, differential delay information and physical random access channel (PRACH) configuration information indicating a set of preambles and a PRACH occasions configuration; determining a set of candidate PRACH occasions, from among a plurality of PRACH occasions of the PRACH occasion configuration, based on the differential delay information; selecting a preamble from a group of the preambles allocated to one candidate PRACH occasion of the set of candidate PRACH occasions; and transmitting the selected preamble using a PRACH resource corresponding to the one candidate PRACH occasion.

Abstract: Method, apparatus, and systems for determining and transmitting positioning information in a wireless communication network are provided. For example, a method for wireless communications comprises receiving configuration information related to a set of positioning configurations and a small data transmission (SDT), determining, based on the configuration information, that at least one positioning configuration of the set of positioning configurations satisfies a positioning requirement and is associated with a payload size being less than a data volume threshold (DVT) associated with the SDT, selecting, from the at least one positioning configuration, positioning configuration associated with a payload size being closest to the DVT, performing a positioning measurement based on the selected positioning configuration, and sending, using an uplink resource for the SDT, a measurement report based on the selected positioning configuration and the positioning measurement.

Abstract: Methods and apparatuses for Sidelink (SL) communication are disclosed herein. A method for SL communication performed by a Wireless Transmit/Receive Unit (WTRU) may comprise determining to transmit Sidelink Control Information (SCI) over a Physical Sidelink Control Channel (PSCCH). The method may further comprise selecting one or more sub-channels from a Physical Sidelink Shared Channel (PSSCH) in which to allocate time and frequency resources for the PSCCH. The method may further comprise allocating time and frequency resources within the PSCCH in which to transmit the SCI. The allocation of time and frequency resources may be based on at least one of an SCI format type, a Layer 1 (L1) Identifier (ID), a priority, or a Quality of Service (QoS) requirement. The method may further comprise transmitting the SCI over the determined time and frequency resources.

Abstract: Methods and apparatuses for link management and recovery for sidelink relays are described herein. Methods may include transmitting packets to a network via a first relay and using a sidelink radio bearer (SLRB) configuration, wherein the transmitted packets include an identifier associated with the first relay: receiving a message identifying alternate relay; and detecting radio link failure. Methods may include obtaining signal quality measurements of reference signals associated with the alternate relay: selecting, from the alternate relay, a second relay having the highest signal quality; and transmitting, to the selected second relay, a reconfiguration message indicating to use the same SLRB configuration or an equivalent SLRB configuration. If a response indicates that reconfiguration of the second relay is successful, a packet may be transmitted via the second relay using the same or equivalent SLRB configuration. The packet may include an identifier associated with the second relay.

Abstract: A method for use in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU is able to communicate with a network through sidelink (SL). The WTRU is configured with a set of scheduling request (SR) configurations. The method comprises: receiving, through the SL, (1) CSI reporting request which requests a CSI report and (2) CSI reporting latency information for the CSI report; starting a timer based on the received CSI reporting latency information; triggering a SR transmission specific to CSI reporting; and determining if a SL grant has been received before the time expires, wherein on a condition that the SL grant has been received before the timer expires, the method further comprises 205 transmitting the CSI report based on the SL grant; on a condition that no SL grant has been received before the timer expires, the method further comprises 206 dropping the CSI report.
