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.

Abstract: There is provided an apparatus in a user equipment, the apparatus comprising including: one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the apparatus to: perform measurements on signals received from a target network entity, wherein the user equipment is connected to a serving network entity and calculate a variance of the measurements over a time period. The one or more processors, and memory storing instructions, when executed by the one or more processors, further cause the apparatus to, in response to determining that the calculated variance is above a threshold value, adjust the transmission of a measurement report from the user equipment.

Abstract: Devices, methods and computer programs for synchronization information determination with respect to neighboring cells in wireless communications are disclosed. A network node device determines enhanced synchronization information related to neighboring cell(s) of a current cell served by the network node device. The network node device transmits the determined enhanced synchronization information via downlink signaling to at least one client device located in the current cell. A client device receives the enhanced synchronization information via the downlink signaling. The client device determines synchronization status data of the neighboring cell(s) with respect to the current cell based on the received enhanced synchronization information. The client device may perform an accelerated search for at least one of the neighboring cell(s) based on the determined synchronization status data.
