Abstract: A method, apparatus, and computer-program product are provided. In the context of a method, the method receives, from a first network node via a source satellite, a system information block, wherein the system information block indicates a random access channel opportunity window in which the user equipment should access the first network node or a second network node. The method includes determining, based on the system information block, an access time within the random access channel opportunity window. The method includes transmitting, to the first network node or the second network node via a target satellite, a random access channel preamble at the access time.

Abstract: Message(s) are created to be transmitted over a geostationary system. The message(s) include coverage information for non-geo stationary satellite(s) in an NTN from PLMN(s). The message(s) are transmitted over the geostationary system. A UE searches for a PLMN. The UE, in response to finding a PLMN transmitting, using a geostationary system, message(s) including coverage information for non-geo stationary satellite(s) in an NTN, receives the message(s). The UE updates preferences used for a list used for PLMN selection to make PLMN(s) corresponding to the coverage information as higher priority than other PLMN(s) in the list. The UE performs cell search(es) for cells from the non-geo stationary satellite(s) using the updated list.

Abstract: Example embodiments of the present disclosure relate to store-and-forward operations in non-terrestrial networks (NTN). In an aspect, a terminal device receives, from a network device of a NTN, data priority information associated with at least one store-and-forward operation performed by the network device in the NTN. The terminal device performs, based on the data priority information, an operation for uplink data of the terminal device. In this way, the limitations on the storage of the satellite and the feeder link capacity are solved. The data transmission is ensured, and the storage of the satellite is maximally utilized.

Abstract: Various example embodiments relate to a solution for non-terrestrial network communication. A user device for non-terrestrial network communication may be configured to receive a paging message from a first network device of a first non-terrestrial network; and in response to the paging message, initiate a random access procedure with a second network device associated with a second non-terrestrial network to establish a radio resource connection with the second network device. Network devices, methods and computer-programs are also provided.

Abstract: Method comprising: receiving, from a first cell of a satellite, a handover command triggering a handover of a terminal from the first cell of the satellite to a second cell of the satellite and an assumed location of the terminal; determining an actual location of the terminal; checking one or more of the following conditions applies: the actual location of the terminal deviates from the assumed location by more than a first threshold, and the actual location of the terminal is on the side of the first cell of the coverage boundary and remote from the coverage boundary by at least a second threshold; preventing the terminal from performing the handover if at least one of the one or more checked conditions is fulfilled.

Abstract: A UE, connected using a current cell served by a first satellite to a BS, receives information from the BS including assistance information for a cell switch from the current cell to a cell served by a second satellite. The information is received before a stop time indicating when the current cell will stop serving the UE. The UE performs the cell switch from the current cell to the cell served by the second satellite using at least the assistance information to find cell synchronization block(s) for the served by the second satellite. The BS sends the information from the BS including the assistance information for a cell switch from the current cell to a cell served by a second satellite. The BS shuts down the current cell at a stop time.

Abstract: Various example embodiments relate to a solution for non-terrestrial network communication. A user device for non-terrestrial network communication may be configured to determine that a connection to a non-terrestrial network having a discontinuous coverage is unavailable, the non-terrestrial network providing at least one cell serving the user device; obtain data relating to cell availability of the at least one cell; determine a backoff time associated with a subsequent non-terrestrial network search based at least partly on the data relating to cell availability; and initiate a cell search of the non-terrestrial network again after expiration of the backoff time.

Abstract: Various example embodiments relate to provision of a positioning time gap in a paging procedure. An apparatus may obtain positioning capability information of a device. The positioning capability information may comprise an indication of a first time period for determining a position of the device with first initial positioning data and an indication of a second time period for determining the position of the device with second initial positioning data. A positioning time gap may be determined based on the positioning capability information of the device. The apparatus may transmit a first signal, but refrain from transmitting a second signal for at least a duration of the positioning time gap from the first signal. Apparatuses, methods, and computer programs are disclosed.
