    Abstract: It is provided a method, comprising measuring, during a period, a first time of arrival (TOA) of a first signal from a first satellite, a second TOA of a second signal from a second satellite, and a third TOA of a third signal from a third satellite; reporting, after the period has elapsed, the first TOA along with the first cell identifier and a first parameter enabling to derive a transmit time of the first signal, the second TOA along with the second cell identifier and a second parameter enabling to derive a transmit time of the second signal, and the third TOA along with the third cell identifier and a third parameter enabling to derive a transmit time of the third signal, wherein the first TOA is measured within a set first interval in the period; the second TOA is measured within a set second interval in the period; the second interval does not overlap the first interval.

    Abstract: A client device, a network node device, methods and computer programs are disclosed. A client device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the client device to receive a timing advance configuration message from a network node device, wherein the timing advance configuration message comprises a plurality of timing advance commands; perform a plurality of consecutive uplink transmissions to the network node device; and apply the plurality of timing advance commands between the plurality of consecutive uplink transmissions.

    Abstract: Systems, methods, apparatuses, and computer program products for dynamic cell-specific delay for timing scaling in a non-terrestrial network (NTN). For example, certain embodiments may utilize a cell-common delay composed of FL and part of SL (until a cell-specific reference surface). A network node (e.g., a gNB) may calculate the cell-common delay as a function of time (T_c(t)) and may provide this function to the UEs (the satellite path may beis deterministic). The function of time may be a combination of two functions representing the FL and SL. The function can may be broadcasted in a system information block (SIB) or transmitted directly to the UE through radio resource control (RRC) signaling when it becomes active, is handed over, and/or regularly updated.

    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.

    Abstract: Example embodiments of the present disclosure relate to a solution for configuring a retransmission in communications. In an aspect, a first device transmits, to a second device, a first indication of a plurality of candidate retransmission configurations. Each of the plurality of candidate retransmission configurations includes a transmission feedback configuration and/or a data retransmission configuration. The first device selects a target retransmission configuration from the plurality of candidate retransmission configurations. The first device transmits, to the second device, a second indication of the target retransmission configuration. The first device communicates with the second device using the target retransmission configuration. The example embodiments of the present disclosure provide a dynamical multi-level indication for a retransmission scheme.
