Abstract: Improved techniques of acquiring A-GNSS data include enabling a terminal UE (T-UE) that is out-of-coverage (OOC) in a 5G NR network to obtain A-GNSS data from an aid UE (A-UE) that is in-coverage in the 5G NR network, the A-UE being configured to access the A-GNSS data from a network node and to provide assistance to a T-UE, and the T-UE being configured to broadcast, via a sidelink connection, a request to obtain A-GNSS data.

Abstract: Embodiments of the present disclosure disclose devices, methods and apparatuses for transforming sampled signal. The terminal device receives, from a network device, a request that the terminal device applies a transformation operation to a sampled signal; obtains a transformed signal by applying the transformation operation to the sampled signal; and transmits the transformed signal to the network device. By the proposed processing for the sampled signal, the terminal device-specific RF and/or baseband (BB) architecture becomes transparent to the network device.
