Abstract: A method is provided that includes scheduling transmission of system information blocks (SIBs) including information elements with assistance information for a first aerospace platform, and a separate at least one information element with assistance information for a second aerospace platform. The first aerospace platform and the second aerospace platform are configured to provide respectively a first non-terrestrial network (NTN) cell and a second NTN cell that are quasi-Earth-fixed cells serving a geographic area for limited periods of time. The method also includes causing a user equipment in the first NTN cell to acquire the separate at least one information element with the assistance information for the second aerospace platform, during a period of time the geographic area is served by the first NTN cell, before the geographic area is served by the second NTN cell.

Abstract: A method, apparatus, and computer program product are provided. In the context of a method, the method receives, from a network node, a message indicating a plurality of physical random access channel configurations and at least one relative location threshold. The message determines, based on comparing a relative location of the user equipment to the relative location threshold, a selected physical random access channel configuration out of the plurality of physical random access channel configurations. The method performs a random access procedure based on the selected physical random access channel configuration.

Abstract: Techniques for signalling TA adjustment during RTT measurement in non-terrestrial networks relayed connection between nodes are provided. For example, a method performed by a terminal node in a non-terrestrial network, comprises: performing a timing advance (TA) adjustment during a round trip time (RTT) measurement; and in response to the TA adjustment exceeding a threshold, providing, to a network node, an indication relating to the RTT measurement to indicate that the TA adjustment exceeds the threshold.

Abstract: In a non-terrestrial network, the delay in reception time may prevent reception of a random access preamble. A combination of increasing transmit power and changing the timing with which the random access preamble is transmitted may enable reception of the random access preamble. One or more criteria may be used to determine whether the timing advance value with which the random access preamble is transmitted should be changed before retransmission is attempted.

Abstract: Various example embodiments relate to a solution for modifying mobility events by making them depend on information which captures a moving cell direction. An apparatus may obtain location information associated with at least one moving neighboring cell. The apparatus may determine, based on the location information, a distance change associated with the at least one moving neighboring cell with respect to a user node location. The apparatus may determine an offset for the at least one moving neighboring cell based on the distance change associated with the at least one moving neighboring cell. The apparatus may apply the offset associated with the at least one moving neighboring cell in a mobility event associated with the at least one moving neighboring cell. Apparatuses, methods, and computer programs are disclosed.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of signalling enabling Timing Advance (TA) exchange between User Equipment (UE) and Radio Access Network (RAN). The method comprises receiving, at a first device, a TA margin from a second device; transmitting, to the second device, information associated with a reference location of the first device at a first time point; determining a reference TA of the first device at least based on the reference location of the first device; determining an actual TA of the first device at least based on an actual location of the first device at a second time point; and determining, based on a comparison of a TA margin with a difference between the reference TA and the actual TA, whether to transmit an updated reference location of the first device to the second device. In this way, the control for uplink overhead from TA/location updates and probability of impacting downlink scheduling become flexible. Furthermore, the downlink delay can be optimised and meanwhile overhead in case of very few small packets transmitted can be minimized. As a result, the network can optimize its own performance and the battery savings of the users.

Abstract: There is provided an apparatus comprising one or more processors, and one or more memories storing instructions that, when executed by the one or more processors, cause the apparatus to perform: receiving, by a user equipment, directional probability information comprising a plurality of directions with probabilities, wherein a probability of a direction of the plurality of directions indicates how probable it is that another use equipment is in that direction; and determining beam widths and beamforming directions based on the probabilities.

Abstract: A base station serving UE(s) receives validity time information for cell(s) formed by other base station(s). The validity time information indicates at least a time period when corresponding cells are available for use by the UE(s). The base station determines action(s) to perform for the UE(s) based on the validity time information. A UE receives, from a base station, validity time for cell(s) formed by other base station(s). The UE performs action(s) based on the validity time of the cell(s).

Abstract: An apparatus, method and computer program is described comprising: determining a set of candidate radio resources for transmitting data from a first communication node of a non-terrestrial network to a second communication node of the non-terrestrial network over a direct radio link; identifying one or more of the candidate radio resources as conflicting radio resources that conflict with at least one scheduled radio transmission in the non-terrestrial network based, at least in part, on a propagation delay associated with the at least one scheduled radio transmission and/or a propagation delay associated with the radio transmission by the first communication node; generating a subset of candidate radio resources by excluding the identified one or more conflicting radio resources from the set of candidate radio resources; and selecting a radio resource from the subset of candidate radio resources for transmitting the data over the direct radio link.
