Abstract: A wireless transmit/receive unit (WTRU) may receive an indication of EDT configuration information. The device may determine (e.g., based on application information, for example application layer information) that a first uplink EDT transmission is triggered for first uplink data. The application layer information may indicate an early data complete response is not required for the first uplink EDT transmission. The device may determine, based on the trigger, an EDT completion response mode to apply based on the received indication. The device may send the first uplink EDT transmission (e.g., including first uplink data) to a network to indicate that no response is expected for the first uplink EDT transmission, and a completion response mode. The device may determine that a completion indication from the network has not been detected before a time threshold. The device may, based on the lack of detection, continue operation in accordance with an idle condition and monitor for a paging message.

Abstract: A wireless transmit/receive unit (WTRU) measures a first candidate cell. The WTRU sends a channel state information (CSI) report to a serving cell. The CSI report includes one or more measurements of the first candidate cell. The WTRU receives a physical downlink control channel (PDCCH) order to transmit a preamble to the first candidate cell. The WTRU determines a time difference between when the CSI report is sent and when the PDCCH order is received. If the time difference is equal to or greater than a threshold, the WTRU transmits a physical random access channel (PRACH) at a first transmission power value. If the time difference is less than the threshold, the WTRU transmits the PRACH at a second transmit power that is an offset greater than the first transmit power value.

Abstract: A wireless transmit/receive unit (WTRU) may be configured for power control for same-PCI satellite switching. The UL TX power required by the WTRU after a satellite switch may vary significantly, for example, due to the large difference in location between former and incoming satellites. If the WTRU uses too little power, the WTRU risks unsuccessful reception. If the WTRU uses too much power, the WTRU risks interference or unnecessary power consumption. The WTRU may estimate free space propagation losses based on known information. For example, the WTRU may estimate propagation losses based on the known the location of the former and incoming satellites (e.g., via assistance information). Using the estimate of free space propagation, the WTRU may scale the UL transmission power for the initial transmission to the incoming satellite based on the delta-distance from the former satellite. The UL transmission power may be additionally controlled by a configuration.

Abstract: A wireless transmit/receive unit (WTRU) may be utilized for performing beam management during a same-physical cell identity (PCI) satellite switch. The WTRU may comprise a processor configured to receive an indication of a time for a same-PCI satellite switch from a first satellite to a second satellite. The processor may receive an indication that a first reference signal in a first time period prior to the same-PCI satellite switch is quasi-collocated (QCL) with a second reference signal in second time period after the same-PCI satellite switch. The processor may be configured to measure the reference signal from the second incoming satellite during the first time period. The WTRU may predict how to re-orient the WTRU spatial filters using a reference signal from a neighboring cell (e.g., SSB/CSI-RS). The processor may be configured to transmit a same-PCI satellite switch confirmation based on the beam direction and the transmit power calculated.

Abstract: A wireless transmit/receive unit (WTRU) may comprise a processor configured time synchronization during a same—physical cell identity (PCI) satellite switch. In one or more cases, prior to a same-PCI satellite switch, the WTRU may receive a configuration for pre-reporting timing advance and assistance information for incoming satellite (e.g., time and incoming satellite position at same-PCI satellite sitch). The WTRU may receive the configuration to reduce TA re-synchronization time and congestion due to large scale TA reporting. The processor may be configured to pre-calculate a timing advance (TA) value to the incoming satellite based on the time and the position of the incoming satellite for the same-PCI satellite switch. The processor may be configured to transmit the pre-calculated TA value according to the pre-reporting configuration. The processor may be configured to apply the pre-calculated TA value to the incoming satellite at the time of same PCI satellite switch.
