    Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

    Abstract: Method and apparatus for an initial E2E discovery procedure in direct NTN networks. The apparatus receives, from a network entity, an indication indicating support for a direct NTN communication. The direct NTN communication between the first UE and at least a second UE bypasses ground-based feeder links. The apparatus transmits, to the network entity, a communication request for the direct NTN communication with at least the second UE based on the indication indicating support for the direct NTN communication. The communication request is transmitted to the second UE via the direct NTN communication. The apparatus receives, from the second UE, a communication request feedback message indicating that the second UE is reachable over the direct NTN communication. The communication request feedback message is received from the second UE via the direct NTN communication.

    Abstract: A method of assessing a reported UE location includes: receiving, at a network entity, the reported UE location; obtaining, at the network entity, a first signal frequency difference indicating a first difference between a received frequency of a first signal received by the UE corresponding to a first transmit signal of a first transmit frequency transmitted from a first non-terrestrial-network node, and a received frequency of a second signal received by the UE corresponding to a second transmit signal of a second transmit frequency transmitted from a second non-terrestrial-network node that is separate from the first non-terrestrial-network node; and providing, by the network entity, a UE location assessment indication based on the first signal frequency difference and a second difference between an expected frequency of the first signal at the reported UE location and an expected frequency of the second signal at the reported UE location.
