US 12,757,150 B2 · Network-based positioning in a non-terrestrial network

Abstract

An approach is provided for network-based positioning in non-terrestrial networks. The approach, for example, involves receiving a downlink position reference signal from a network node of a non-terrestrial network. The approach also involves determining whether the user device is in either line-of-sight or non-line-of-sight with respect to a network node of a non-terrestrial network. The approach further involves performing at least one of: (a) based on determining that the user device is in line-of-sight, transmitting a sounding reference signal for positioning to the network node; and (b) based on determining that the user device is in non-line-of-sight, transmitting the sounding reference signal for positioning to the network node for a number of repetitions.

Dependent claims

A user device comprising:

at least one processor;
and
at least one memory storing instructions that, when executed with the at least one processor, cause the user device at least to perform:
receiving a downlink position reference signal from a network node of a non-terrestrial network;
determining whether the user device is in either line-of-sight or non-line-of-sight with respect to the network node of the non-terrestrial network;
and
performing at least one of:
based on determining that the user device is in line-of-sight, transmitting a sounding reference signal for positioning to the network node;
or
based on determining that the user device is in non-line-of-sight, transmitting the sounding reference signal for positioning to the network node for a number of repetitions, wherein a waiting time is included until a first repetition of the number of repetitions.
