Abstract: A wireless transmit receive unit (WTRU) may receive, via configuration information, at least one prohibition condition configured to prohibit GNSS activity. The GNSS activity may comprise at least one of GNSS acquisition, GNSS reporting, or GNSS assistance information (AI) reporting. The WTRU may identify a trigger related to the GNSS activity. The WTRU may determine whether a prohibition condition is activated. The prohibition condition may comprise a condition based on a prohibition timer, a condition based on GNSS validity duration, or a condition based on a characteristic of the WTRU. When the prohibition condition is determined to be active, the WTRU may perform the GNSS activity in response to an override or termination of the prohibition condition and based on the prohibition condition being determined to be active.

Abstract: A device (e.g., a wireless transmit/receive unit (WTRU)) may determine which information (e.g., among multiple transport blocks (TBs)) to be sent on resource(s) of a physical uplink channel (PUCCH) transmission occasion of a configured grant (CG). In an example, the device may receive configuration information. The configuration information may indicate a resource associated with the CG. The device may determine whether to transmit (e.g., on the resource associated with CG) first information of a first TB or second information of a second TB based on one or more of downlink feedback information (DPI) reception, a reason why information of a TB (e.g., the first TB or the second TB) has not been sent in a prior transmission, and a nature of the content (e.g., control information vs. data) in the TB. The first TB may comprise the first information and the second TB may comprise the second information.

Abstract: Extended Reality (XR) applications may require high throughput and very low latency. New Radio (NR) Wireless receiver/transmitter units (WTRUs) running XR applications (XR-WTRUs) may be confronted with link failures when these applications are used in dense urban or indoor environments because of these devices operating in the millimeter band. Methods and devices are provided therefore for performing cell selection and beam management proactively to avoid link failure due to objects being in line of sight between the XR-WTRU and a network node with which it has established a connection. XR-WTRUs may therefore perform visual sensing that may enable visualizing current and future radio environment and using this information to prevent link failures by handing the XR-WTRU over to an alternative network node in line of sight of the XR-WTRU before the XR-WTRU is no longer in line of sight of the network node with which it has established a connection.

Abstract: Methods and apparatus are described herein. A wireless transmit/receive unit (WTRU) includes a receiver, processor, and a transceiver. The receiver is configured to receive, from a base station (BS), configuration information that includes a WTRU-specific fixed frame period (FFP) and one or more configured grant (CG) resources. The processor is configured to determine whether to transmit data using a first CG resource of the one or more CG resources and whether to use either the B S-initiated channel occupancy time (COT) or a WTRU-initiated COT. The processor further performs a listen before talk (LBT) based on the COT the WTRU determined to use; and on a condition that the LBT was successful, a transmitter configured to transmit the data and uplink control information (UCI) in the first CG resource.

Abstract: A WTRU operating in an inactive state may be associated with a first cell. The WTRU may be configured to receive configuration information for a time period associated with small data transmission failure detection and a search space associated with small data transmission. The WTRU may be configured to send a first small data transmission and start the time period. The WTRU may be configured to monitor for a downlink transmission in the search space during the time period. If a condition for cell reselection is satisfied during the time period or the restarted time period, the WTRU may be configured to suspend a data radio bearer (DRB) associated with small data transmission, select a second cell, perform a random access procedure associated with the second cell, and send a small data transmission. The random access procedure may include sending a request to resume a radio resource control (RRC) connection.

Abstract: A wireless transmit/receive unit (WTRU) may identify a plurality of candidate satellite constellations. The WTRU may determine an elevation angle and/or an orbit associated with each of the plurality of candidate satellite constellations. The WTRU may select a satellite constellation from the plurality of candidate constellations for sell selection. The WTRU may identify a plurality of candidate beams associated with the selected satellite constellation. The WTRU may determine an RSRP/RSRQ for each of the plurality of candidate beams. The WTRU may determine a weighted ranking of the plurality of candidate beams. The WTRU may determine the weighted ranking using the determined RSRP/RSRQ, prevailing load intensities, elevation angle, dwelling duration, link switch probability, and/or a quality of service (QoS). The WTRU may select a beam from the plurality of candidate beams for cell selection. The WTRU may select the beam based on the weighted ranking.

Abstract: Methods and apparatus for downlink small data reception in wireless communications are provided. In an example, a method includes receiving configuration information for small data transmission (SDT), and the configuration information indicates one or more uplink (UL) configured grants (CGs), one or more downlink (DL) CGs, and a Transport Block Size (TBS) threshold for SDT; receiving a DL data transmission using a DL CG of the one or more DL CGs; determining a TBS, a HARQ feedback, and a Data Radio Bearer (DRB) associated with the received DL data transmission; and transmitting, using an UL CG of the one or more UL CGs, the HARQ feedback associated with the received DL data transmission, based on a determination that the TB S associated with the received DL data transmission is less than the TBS threshold and/or the DRB associated with the received DL data transmission supports SDT.

Abstract: Systems and methods are described for QoS procedures supporting verticals in wireless systems. Data flows may combine or remap for QoS remapping conditions or state transitions. Data flow remapping may be indicated by triggering a B SR/SR or by multiplexing in the PDU. A non-default set of LCP parameters may be applied for an LCH after a QoS state transition, QoS remapping trigger, or LCP parameter suspension/override. A WTRU may operate according to a QoS adaptation state corresponding to a set of parameter values for a group of data flows, radio bearers, and/or logical channels. A WTRU may transition between QoS adaptation states. An RRC configuration and/or a MAC function may adapt to changing QoS requirement(s). QoS requirement(s) may adapt to changing MAC functions. QoS may be associated with survival time(s). QoS may adapt to higher layer indications. Packet forwarding may adapt to QFI in DL for QoS state changes.

Abstract: The WTRU may monitor for a downlink transmission in a first monitoring occasion of a first search space. The first monitoring occasion of the first search space may be associated with a first monitoring occasion pattern. The WTRU may monitor for the downlink transmission in a second monitoring occasion of a second search space. The second monitoring occasion of the second search space may be associated with a second monitoring occasion pattern. The first search space and the second search space may belong to a search space subset. The WTRU may receive the downlink transmission in the second monitoring occasion of the second search space. The downlink transmission may include a skipping indication. Based on the WTRU receiving the skipping indication in the downlink transmission in the second monitoring occasion of the second search space, the WTRU may apply skipping to the second search space and the first search space.

Abstract: A wireless transmit/receive unit (WTRU) may determine a first set of beams and a second set of beams, that a respective quality of each beam in the first set of beams is less than a predetermined quality value, and that a beam that is in the second set of beams and not in the first set of beams has a quality that is equal to or greater than the predetermined quality value. The WTRU may select the beam that is in the second set of beams and not in the first set of beams and whose quality is equal to or greater than the predetermined quality value, for a BFR and send a message that indicates the selected beam for the BFR to abase station (e.g., a gNodeB). The WTRU may receive a message comprising the selected beam from the gNodeB.

Abstract: A method and apparatus for receiving a broadcast configuration indicating when a change in a RAN function termination occurs is provided, for example, by a timer value. The broadcast configuration may be received from a satellite, blimp or other moving transmitter. A dedicated configuration may also be received from the serving cell. The dedicated configuration may include a preamble, a transient configuration and an indication of a layer 2 behavior. If a WTRU detects a change in RAN function termination, the WTRU may suspend any uplink data transmissions, apply the transient configuration and transmit the preamble to a target cell. The WTRU may synchronize with the target cell and apply the layer 2 behavior.
