Localization estimation for non-terrestrial networks

An apparatus comprising:

• at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• measure, during a reporting period, a first received power of a first signal from a first satellite identified by a first cell identifier, a second received power of a second signal from a second satellite identified by a second cell identifier, and a third received power of a third signal from a third satellite identified by a third cell identifier;
• report, after the reporting period has elapsed, an indication of the first received power along with the first cell identifier, a first absolute time when the first received power is measured, and a first parameter enabling to derive a transmit power of the first signal, an indication of the second received power along with the second cell identifier, a second absolute time when the second received power is measured, and a second parameter enabling to derive a transmit power of the second signal, and an indication of the third received power along with the third cell identifier, a third absolute time when the third received power is measured, and a third parameter enabling to derive an absolute transmit power of the third signal;
• wherein the at least one processor and the computer program code configured to cause the apparatus to measure comprises the at least one processor and the computer program code configured to cause the apparatus to:
• measure the first received power within a set first measurement interval in the reporting period;
• and
• measure the second received power within a set second measurement interval in the reporting period;
• and
• the second measurement interval is different from the first measurement interval by a minimum time interval.

An apparatus comprising:

• at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• measure, within a set first measurement interval during a set reporting period, at least one of a first time of arrival of a first signal from a terminal, a first angle of arrival of a second signal from the terminal, and a first round trip time of a third signal from the terminal and to measure, within a set second measurement interval during the reporting period, at least one of a second time of arrival of a fourth signal from the terminal, a second angle of arrival of a fifth signal from the terminal, and a second round trip time of a sixth signal from the terminal;
• report, after the reporting period has elapsed, an identification of the terminal, an identification of a satellite comprising the apparatus, an indication of the measured at least one of the first time of arrival, the first angle of arrival, and the first round trip time along with an identification of the respective at least one of the first, second, and third signals, and a respective first absolute measuring time when the respective at least one of the first time of arrival, first angle of arrival, and first roundtrip time is measured, and an indication of the measured at least one of the second time of arrival, the second angle of arrival, and the second round trip time along with an identification of the respective at least one of the fourth, fifth, and sixth signals, and a respective second absolute measuring time when the respective at least one of the second time of arrival, second angle of arrival, and second roundtrip time is measured, wherein
• the first measurement interval does not overlap the second measurement interval.
