A method for operating a base station is provided. The method includes in response to a triggering event, fetching information on a base station (BS) configuration parameters comprising a location, a height, an antenna pattern, and topographical details surrounding the BS; determining the BS configuration parameters that are error prone and require re-estimation; obtain measurement reports created by at least one user equipment (UE); determining an audit method to perform an audit correction, the audit correction based on the one or more of the BS configuration parameters to re-estimate, available BS information and the measurement reports; performing the audit correction, to obtain a result based on a computed score for each candidate value of the BS configuration parameters; generating, based on the result, one or more corrective actions; and adjusting at least one of the BS configuration parameters based on the one or more corrective actions.
Lean Deterministic Beam/Power Feedback During 5G/6G Initial Access
For efficient communication in 5G and 6G, transmission beams are to be aligned with each user device as soon as possible during the initial access procedure. Prior-art procedures for downlink beam alignment consume large amounts of power and resources. Therefore, low-complexity formats and procedures are disclosed for a new user device to indicate its angular position relative to the base station upon entering the network. In one embodiment, the SSB message is broadcast isotropically, along with test signals which are transmitted in different directions. The user device indicates which test signal is best received, thereby indicating its angular direction. In a second embodiment, the test signals and feedback messages are appended to various entry messages after initial contact. Using either method, the base station and user device can then aim their beams toward the other, for enhanced signal quality thereafter.

Vehicle routing evaluation based on predicted network performance
A vehicle routing evaluation system makes predictions about network performance data along road segments relevant to navigation of a vehicle and generates routing instructions or recommendations based in part on the network performance data. The vehicle routing evaluation system may send control signals to automatically control navigation of the vehicle to follow the routing generated routing or may present the navigation instructions to a teleoperator that controls the vehicle. Alternatively, the vehicle routing evaluation system generates a display with a navigational map overlay providing visual cues indicative of predicted wireless performance along various road segments to enable the teleoperator to select between possible routes.
