    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： Methods and apparatus, including computer program products, are provided for non-terrestrial networks. In some example embodiment, there may be provided a method including determining, based on position information, a country where the apparatus is located; receiving, from a non-terrestrial base station, a system information broadcast including mapping information, the mapping information including a country area identifier or a random access radio network temporary identifier; mapping the determined country into the received country area identifier or the received random access radio network temporary identifier; and performing, based on the received country area identifier or the received random access radio network temporary identifier, a random access procedure with the non-terrestrial base station.
