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.

Abstract: Systems, methods, and instrumentalities are described herein for data transfer with energy harvesting (EH). EH may offer zero-energy consumption data communication. EH may impose intermittent connection drops due to battery shortage. If a certain condition is met (e.g., battery shortage), the RRC state or DRX/DTX configuration may be switched and data transfer operation may be suspended. EH may be performed to charge the battery/capacitor of the WTRU in the changed RRC state (e.g., new RRC state) or in a changed DRX/DTX operation (e.g., new DRX/DTX operation). If the state is transitioned or the DRX/DTX configuration is changed, protocol times (e.g., via all protocol timers) may be suspended and the user data maintained so that the transmitter and the receiver entities may resume data communication without any data loss or with very small loss of data.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to receive configuration information from a network indicating first reporting behavior and second reporting behavior to be applied when reporting measurements associated with a beam. The configuration information may indicate a condition associated with a height of the WTRU, a speed of the WTRU, and/or a location of the WTRU. The WTRU may be configured to determine whether the condition associated with the height of the WTRU, the speed of the WTRU, and/or the location of the WTRU has been satisfied. The WTRU may be configured to send a report indicating the beam measurements of the candidate set of cells using the first reporting behavior or the second reporting behavior based on whether the condition associated with the height of the WTRU, the speed of the WTRU, and/or the location of the WTRU has been satisfied.

Abstract: A wireless transmit/receive unit (WTRU) may comprise a processor and memory. The processor and memory may be configured to receive configuration information indicating measurement relaxation criteria for radio link monitoring (RLM) or beam failure detection (BFD) and a prohibit time period for reporting a measurement relaxation state. The WTRU may determine that the measurement relaxation state of the WTRU has changed based on the measurement relaxation criteria. The WTRU may determine that the prohibit time period has ended. The WTRU may send a report based on the determination that the measurement relaxation state has changed and the determination that the prohibit time period has ended. The report may include an indication of a measurement relaxation state.

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 wireless transmit/receive unit (WTRU) may be configured to implement layer 1/layer 2 (L1/L2) based inter-cell mobility procedures with reduced latency during handover or other mobility operations. The WTRU may be configured to receive configuration information associated with a plurality of candidate cells. The configuration information may be associated with a physical layer measurement for each candidate cell. The configuration information may include a measurement criteria. The WTRU may be configured to determine a subset of the plurality of candidate cells, with each candidate cell in the subset determined based on the measurement criteria. The WTRU may be configured to send a report indicating the subset. perform a physical layer measurement on the subset, and receive an indication to perform layer handover to a candidate cell of the subset.

Abstract: A WTRU may receive an indication of a set of baseline configurations (e.g., the set of baseline configurations or a pointer/index to the set of baseline configurations). The set of baseline configurations may include at least a first baseline configuration and a second baseline configuration. The WTRU may receive first information (e.g., a first signature), wherein the first information indicates that the first baseline configuration is a selected baseline configuration (e.g., a current SI baseline). The first information may be received via the low power receiver. The WTRU may receive and/or determine scheduling information. The scheduling information may include at least an indication of a first schedule associated with first update information. The WTRU may receive, in accordance with the first schedule, second information (e.g., a second signature). The second information may indicate the first update information (e.g., the first update information indicating an update to the selected baseline configuration).
