Device positioning

An apparatus comprising at least one processing core and at least one memory storing instructions that, when executed by the at least one processing core, cause the apparatus at least to:

• process a measurement instruction received in the apparatus from a cellular communication system,
• wherein the cellular communication system comprises satellite-based non-terrestrial cells,
• wherein the apparatus is configured to perform the receiving of the measurement instruction from a first satellite-based non-terrestrial cell of the cellular communication system;
• based on the measurement instruction, measure a received signal strength of a signal from each cell of a first cell set and each cell of a second cell set, the first cell set and the second cell set comprising cells of the cellular communication system,
• wherein the cells in the first cell set and the second cell set are all satellite-based non-terrestrial cells,
• wherein the received signal strength of the signal from each cell of the first cell set and each cell of the second cell set are obtained as a reference signal received power (RSRP) value expressed in a logarithmic scale in decibels,
• wherein the cells in the first cell set and the second cell set are comprised in neighboring cells of a cell in which the apparatus is attached, and
• wherein the first cell set and the second cell set are compiled such that the first cell set and the second cell set comprise cells on different sides of an orbital plane of a satellite, the first cell set comprising cells to the left of the orbital plane and the second cell set comprising cells to the right of the orbital plane;
• and
• determine a first signal strength value for the first cell set and a second signal strength value for the second cell set, and report to the cellular communication system a value obtained from the first signal strength value and the second signal strength value,
• wherein the first signal strength value is a weighted average of signal strengths measured from the cells in the first cell set and the second signal strength value is a weighted average of signal strengths measured from the cells in the second cell set,
• wherein the apparatus is configured to perform the obtaining of the value from a ratio of the first signal strength value to the second signal strength value, wherein obtaining the value from the ratio of the first signal strength value to the second signal strength value comprises rounding the ratio to be expressed using a predetermined number of bits, and
• wherein the apparatus is configured to perform the reporting of the value to the first satellite-based non-terrestrial cell of the cellular communication system.
