Abstract: Methods for resource efficient data transmission are described herein. A method may comprise operating in one of an idle or an inactive mode and transmitting, in response to a random access (RA) message or a configured grant (CG), a small data transmission over an uplink channel. The RA message may be received in a two-step RA procedure or a four-step RA procedure. The method may further comprise transitioning from the idle or the inactive mode to a connected mode. The method may further comprise determining resources for transmitting the small data transmission. The method may comprise determining whether the small data transmission was successfully received and retransmitting, on a condition the small data transmission was not received, the small data transmission. The method may further comprise segmenting a small data packet into a plurality of small data packets and transmitting the small data packets in a plurality of transmission opportunities.

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 a base station (e.g., a gNodeB). The WTRU may receive a message comprising the selected beam from the gNodeB.

Abstract: Systems, methods, devices, and instrumentalities are described herein relate to partial or delta updated flight path reporting. A wireless transmit/receive unit (WTRU) may transmit a first message indicating flight path information is available. The WTRU may receive a second message including a flight path reporting configuration. The flight path reporting configuration may request the flight path information. The WTRU may transmit an initial flight path message within a third message. Based on information associated with changing from a previous flight path to an updated flight path, the WTRU may detect that a previous flight path is required to be updated with an updated flight path. The WTRU may transmit an indication that the updated flight path is available. The WTRU may receive a request for and subsequently transmit partial or delta updated flight path information.

Abstract: Systems, methods, and instrumentalities are disclosed herein associated with receiving a triggering configuration for starting and/or stopping a dual connection with a cell (e.g., second cell), where the triggering configuration may be the same or different for the uplink (UL) and downlink (DL). A configuration may be received regarding the WTRU UL behavior for faster activation of the target cell (e.g. faster channel quality indicator (CQI) reporting prior to starting the connection towards the second cell), which may include triggering conditions for starting the UL signaling. The triggering conditions may be monitored for starting the UL signaling towards/regarding the second cell for faster activation. In examples the triggering conditions may be monitored for starting the connection towards the second cell.

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 is configured to receive information to transmit uplink data indicating a first number of nominal repetitions and a first number of symbols for transmission in each of the first number of nominal repetitions. The WTRU is configured to determine a set of symbols associated with a first nominal repetition of the first number of nominal repetitions and is configured to transmit, based on the set of symbols associated with the first nominal repetition, a second number of actual repetitions in symbols associated with the first nominal repetition. The second number of actual repetitions and the symbols used to transmit the second number of actual repetitions are based on an occurrence of an event during the set of symbols associated with the first nominal repetition. The second number of actual repetitions is determined based on whether the event is a COT and the COT is initiated by the WTRU.

Abstract: A wireless transmit/receive unit, WTRU, receives a plurality of positioning reference signals from a plurality of terrestrial transmission points, the positioning reference signals including at least one positioning reference signal from a first terrestrial transmission point and at least one positioning signal from a second terrestrial transmission point, on condition that at least one value based on first measurements of the plurality of positioning reference signals satisfies a condition, transmits a request to initiate, at the WTRU, positioning using positioning reference signals received from satellites, received, in response to the request, information about a set of satellites, selects at least one satellite from the set of satellites, determines a second position estimate for the WTRU based on at least one positioning reference signal received from at least one selected satellite, and sends to a network node a message comprising information indicating the second position estimate for the WTRU.

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 performing a channel access procedure and transmitting a set of repetitions is disclosed. A wireless transmit/receive unit (WTRU) may be configured to receive information to transmit uplink data. The information may indicate a first number of nominal repetitions and a first number of symbols for each of the first number of nominal repetitions. The WTRU may be configured to determine a set of symbols associated with a first nominal repetition and to transmit a second number of actual repetitions in symbols associated with the first nominal repetition. The second number of actual repetitions and the symbols used to transmit the second number of actual repetitions may be based on an occurrence of an event during the set of symbols associated with the first nominal repetition. The set of symbols associated with the first nominal repetition may comprise one or more subsets of consecutive uplink symbols.
