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.

Methods and apparatus for PUSCH repetition

Systems, methods, devices, and instrumentalities are described herein relate to explicit requests for flight path statuses. 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 flight path reporting configuration may include at least one of: a number of waypoints; whether to include timestamp information; or a configuration to periodically report flight path information updates. The WTRU may transmit an initial flight path message within a third message. At a configured periodicity, the WTRU may evaluate whether the flight path information has changed since a previous flight path report was transmitted.

Explicit request for flight path status

Systems, methods, devices, and instrumentalities are described herein related to conditional triggers for flight path update indications. A wireless transmit/receive unit (WTRU) may receive configuration information. The configuration information may indicate a trigger condition (e.g., threshold) associated with enabling transmission of a flight path update indication. The WTRU may determine that the threshold associated with enabling transmission of the flight path update indication is satisfied. Based on the threshold being satisfied, the flight path update indication may be transmitted. The WTRU may receive a request to transmit the updated flight path information and transmit the updated flight path information.

Conditional trigger for flight path update indication

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.

Idle/inactive mobility for small data transmission

A method performed by a WTRU may comprise receiving a plurality of LBT configurations associated with one or more of a beam, a BWP, a LCH, a set of LBT parameters, a transmission type or an LBT subband. The method may further comprise receiving an indication to transmit using a first LBT configuration of the plurality of LBT configurations. An attempt to acquire a channel may then be made using the first LBT configuration. The indication to transmit may additionally indicate a second LBT configuration of the plurality of LBT configurations. Data may be transmitted on the channel when the attempt to acquire the channel is successful. An attempt to acquire the channel using the second LBT configuration of the plurality of LBT configurations may be made when the attempt to acquire the channel using the first LBT configuration fails.

Methods for channel access management

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.

Methods and apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.

Methods and apparatus for wireless transmit/receive unit (WTRU) power control

A wireless transmit/receive unit (WTRU) may communicate in a non-terrestrial network (NTN) comprising a plurality of satellites. The WTRU may be preconfigured with a plurality of measurement configurations and a corresponding plurality of activation/deactivation criteria associated with the plurality of satellites. The activation/deactivation criteria includes at least activation timing information. The WTRU may activate and deactivate each of the plurality of measurement configurations over time in accordance with the activation/deactivation criteria. The WTRU may perform measurements on cell beams for satellites with active measurement configurations and report results based on the measurements to NTN.

Methods for radio resource management in moving networks

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.
