Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for determining radio frequency (RF) conditions using sensing information. A network node may construct a map of RF conditions associated with location information within its coverage area. The network node may configure a radio resource control (RRC)-connected UE to operate in an RF sensing mode. The network node may obtain a positioning of the UE from a sensing node. The network node may determine the RF conditions of the UE based on its position using the map.

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.

Abstract: Systems, methods, apparatuses, and computer program products for calibrating beam orientation errors for improved positioning. For example, certain embodiments may utilize collection of various measurements to compute, and correct for, beam orientation errors. Additionally, or alternatively, certain embodiments may collect information about propagation conditions in a network and may establish virtual anchors for the network.

Abstract: A network element estimates a position of a user equipment served by a first network and a second network. At the network element, at least one memory and computer program code are configured to, with at least one processor, cause the network element to: determine first position measurement information for the user equipment in the first network; obtain position assistance data associated with the second network, the position assistance data including at least second position measurement information for the user equipment in the second network; obtain frequency offset information and time offset information for transmissions in the first network and transmissions in the second network; and estimate a position of the user equipment based on the first position measurement information, the second position measurement information, the frequency offset information and the time offset information.

Abstract: Systems, methods, apparatuses, and computer program products for timing advance (TA) validation and/or adjustment, for example in 5G NR, are provided. One method may include configuring, by a network node, at least one user equipment for at least one preconfigured uplink resource (PUR), and, before moving to idle or inactive mode, configuring the at least one user equipment to measure time of arrival (TOA) on a plurality of beams from a plurality of network nodes and to determine reference signal time difference (RSTD) values (600). The method may also include receiving data from the at least one user equipment using the at least one preconfigured uplink resource (PUR) (630).
