Abstract: Methods, systems, and apparatuses for use in wireless communication are disclosed. A method performed by a wireless transmit/receive (WTRU) unit may compromise: receiving information indicating a first tracking area code (TAC) and first TAC validity time information; registering with a network using the first TAC; receiving information indicating a second TAC and second TAC validity time information; determining, based on the first TAC validity time information and the second TAC validity time information, a time period wherein both the first TAC and second TAC are valid; selecting a time within the time period; and transmitting, at the selected time, a connection request.

Abstract: A WTRU may receive downlink control information (DCI) from a first transmission/reception (TRP). The DCI may indicate that the WTRU is to transmit a physical random access channel (PRACH) transmission. The DCI may include an indication of a preamble, an indication of a first PRACH mask, and/or an indication associated with a first synchronization signal block (SSB), and/or an indication of a reference signal (RS). The WTRU may be configured to transmit the preamble, to a second TRP, the preamble in a first PRACH resource. The first TRP and/or the second TRP may be associated with a same physical cell identity (PCI). The WTRU may receive, from the second TRP, a first response to the preamble. The first response may include a first timing advance (TA) command for the second timing alignment for transmission to the second TRP and/or an index indicating the second TRP.

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 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 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: 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.

Abstract: Methods, apparatuses, and systems for determining and communicating positioning information in a wireless communication network are provided. For example, a method implemented by a wireless transmit/receive unit (WTRU) includes receiving information indicating a set of position reference signal (PRS) configurations and cluster information. Each PRS configuration is associated with a respective cluster and respective cluster information. The method also includes determining a first location of the WTRU using a first PRS configuration, selecting a cluster that encompasses the first location and is associated with a second PRS configuration, determining a second location of the WTRU based on the second PRS configuration, and transmitting second information indicating the second location of the WTRU and respective cluster information of the selected cluster.

Abstract: A wireless transmit/receive unit (WTRU) may comprise a processor. The processor may be configured to receive (e.g., via broadcast) configuration information indicating a time that a same-PCI satellite switch may occur. In one or more examples, the WTRU may transmit assistance information prior to the same-PCI satellite switch. The assistance information may, for example, include a re-synchronization duration, capabilities to synchronization procedures, and/or a time indication for resuming TX and/or RX. The WTRU may receive configuration information for satellite re-synchronization. The WTRU may perform the same-PCI satellite switch to the second satellite, for example, based on the configuration information indicating the time for the same-PCI satellite switch. In performing the same-PCI satellite switch, the WTRU may start a resynchronization gap, suspend UL TX and/or DL RX, and/or perform re-synchronization procedure(s).

Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information that indicates associated random access channel occasions (ROs). for example, a first RO and a second RO. The WTRU may determine a feature combination associated with the WTRU. The WTRU may determine a set of preambles based on the feature combination associated with the WTRU. The set of preambles may include multiple subsets of preambles, for example, a first subset of preambles associated with the first RO of the associated ROs and a second subset of preambles associated with the second RO of the associated ROs. The WTRU may transmit a first preamble of the first subset of preambles on the first RO of the plurality of associated ROs and a second preamble of the second subset of preambles on the second RO of the plurality of associated ROs.
