Abstract: Methods, apparatus, systems and procedures to manage a multicast communication to a multicast group implemented by a respective wireless transmit/receive unit (WTRU) of WTRUs in the multicast group are disclosed. One representative method includes receiving, by the respective WTRU of the multicast group, a configuration, the configuration indicating a Random Access Channel (RACH) preamble to use for a negative acknowledgement (NACK) response to a multicast transmission to the respective WTRU, monitoring, by the respective WTRU, for data of the multicast transmission, determining, by the respective WTRU, whether the monitored for data was successfully received; and on condition that the monitored for data was not successfully received, sending, by the respective WTRU, the RACH preamble indicated by the received configuration.

Abstract: A method performed by an anchor wireless transmit/receive unit (WTRU) having an Extended Reality (XR) application includes transmitting to a base station (BS) a request for a candidate set of collaborative WTRUs, the request including pose information to identify the candidate set of collaborative WTRUs, receiving from the BS a first set of collaborative WTRUs, determining, by the anchor WTRU, a second set of WTRUs from the first set of WTRUs that align with at least one of a Field of View (FoV) requirement, the pose information, and XR application parameters of the anchor WTRU, and transmitting, to the BS, an indication of the second set of WTRUs as selected collaborative WTRUs.

Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

Abstract: Methods and apparatus for recovering from a beam failure in a non¬terrestrial communication network are provided. A method may include receiving (610) configuration information indicating a first set of RSs including one or more first RSs associated with a first BWP of a cell, and second sets of RSs that each include one or more second RSs associated with a second BWP. The method may include determining (620) a candidate set of RSs from the plurality of second sets of RSs based on any of a location and a timing advance value associated with the WTRU, selecting (630) an RS from the candidate set of RSs that have measured signal characteristics that satisfy a threshold, and transmitting (640) a PRACH transmission associated with the selected RS in the one of the one or more second BWPs associated with the selected RS during a period in which current operation with the first BWP is suspended.

Abstract: Methods, apparatuses, systems, etc., directed to performing positioning of a wireless transmit/receive unit (WTRU) while it is in idle mode and/or inactive mode (collectively “idle/inactive mode”) in NR are disclosed herein. Performing positioning, including positioning measurement and/or reporting, in idle/inactive mode may allow for increased positioning accuracy and/or decreased latency of location determination. In various embodiments, a WTRU in idle/inactive mode may transmit a positioning measurement report in various ways, including (i) in a Random-Access Channel (RACH) preamble; (ii) appended to a RACH preamble; and/or (iii) in a Physical Uplink Shared Channel. In various embodiments, a WTRU in idle/inactive mode may transmit uplink-based positioning related reference signals. In various embodiments, a WTRU in an idle/inactive mode may transmit, over a dedicated physical channel, (e.g., downlink) positioning measurement reports and/or reference signals (RSs) for uplink positioning measurements.
