Abstract: Various examples and schemes pertaining to utilization of assistance information for compensation for Doppler shift in non-terrestrial networks (NTNs) are described. A user equipment (UE) receives assistance information via an access link from a network node of an NTN such as a satellite or an unmanned aircraft system (UAS) platform. The UE then performs an operation with respect to communications with the network node based on the assistance information such as cell re-selection or beam switching.

Abstract: A method of reference signal received power (RSRP) reporting for New Radio (NR) high resolution angle-based downlink positioning is proposed. UE measures positioning reference signal (PRS) resource sets by performing beam sweeping for a coarse direction search, and then fixes RX beam for RSRP measurements. UE derives RSRP measurement results for each PRS resource set, which comprises multiple PRS resources. UE reports RSRP measurement results of a portion of PRS resource sets. The reported RSRP measurement results comprise an RSRP ratio or a differential RSRP with respect to a highest RSRP value of a PRS resource in a reported PRS resource set.
