    Abstract: A wireless transmit/receive unit (WTRU) may be configured to receive a primary synchronization signal (PSS) scrambled with a first sequence and to determine a PSS sequence index (uk) associated with the PSS and a first sequence index (wi) associated with the first sequence. The WTRU may be configured to determine a first parameter set based on the PSS sequence index (uk) and the first sequence index (wi) and to send information using at least one parameter from the determined first parameter set. The first parameter set may be associated with a waveform. The first parameter set may comprise at least one of: an indication of a waveform type and an indication of a multiplexing scheme. The information may be a physical random access channel (PRACH) transmission. The WTRU may be configured to determine a first offset based on the PSS sequence index (uk) and the first sequence index (wi).

    Abstract: A WTRU may be configured to perform adaptive on-demand positioning. The WTRU may receive configuration information for receiving positioning signals (PRSs) from a first set of one or more TRPs. For example, the configuration information may comprise PRS configuration information associated with each of the first set of TRPs. The WTRU may determine a metric (e.g., a weight, rank, etc.) associated with TRP that is not included in the first set of one or more TRPs. For example, the metric may be determined (e.g., using an AI/ML model) based on: a location associated with the TRP, a location associated with the WTRU, and/or a measurement associated with the TRP. The WTRU may send a PRS activation request to activate PRS from the TRP. For example, the PRS activation request may indicate the PRS configuration that the WTRU requests be activated, and a metric associated with that PRS configuration.

    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: Systems, devices, and methods are disclosed for determining one or more clear channel assessment occasions. Techniques include performing one or more clear channel assessment (CCA) processes on a channel during the one or more CCA occasions to determine whether the channel is available at the one or more CCA occasion based on the one or more CCA processes. Techniques include sending the UL transmission in one or more UL subframes via the channel on at least a condition that the channel is determined to be available at the one or more CCA occasions. Techniques include performing the one or more CCA processes on the channel during another of the one or more CCA occasions on at least a condition that the channel is determined to be unavailable at a previous CCA occasion.

    Abstract: The disclosure pertains to methods and apparatus for network energy savings. A method may be implemented in a wireless transmit/receive unit (WTRU). The method may include receiving configuration information indicating a pattern of time periods during which a cell is available or unavailable and receiving a downlink control information (DCI) comprising an indication associated with an availability of the cell. The method may include determining that a resource may be included in a time period during which the cell may be determined by the WTRU to be available based on the indicated pattern of time periods and the indication. The method may include transmitting or receiving in the resource based on the resource being included in the time period during which the cell may be available.
