Abstract: An apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: determine Doppler shift information per transmission reception point per frequency hopping block; combine the frequency hopping blocks associated with positioning reference signals received from a transmission reception point per transmission reception point; determine a time of arrival of the received positioning reference signals per transmission reception point, based on the combined frequency hopping blocks; transmit, to a location management function, at least one of: an average speed of the apparatus from the respective transmission reception point over the frequency hopping blocks, or an adjusted positioning measurement based on at least one of the determined time of arrival, a Doppler frequency, and a speed of the apparatus; and transmit, to the location management function, the time of arrival per transmission reception point.

Abstract: Systems, methods, apparatuses, and computer program products for using angle error groups (AEGs) to improve angle of arrival (AoA) positioning may be provided. For example, for a specific received signal, one or more receiving antenna elements that can be considered to have almost the same incident angle within a certain margin may be defined as a group. The group of receive (Rx) antenna elements (or a group of Rx antennas) may be defined as an AEG. The configuration of an AEG for each TRP and the AEG may be used for AoA measurement and reporting. The gNB or transmit receive point (TRP) may perform AoA measurements and may determine an AoA for the AEGs.
