Abstract: A fallout engine performs fallout handling for workflows in deploying a cell site and helps to ensure that any errors in operations performed in earlier stages are addressed before moving onto a later stage. The fallout engine identifies the occurrence of one or more errors that occur during a pre-check before execution of the stage, during the execution of the stage, or a post-check after execution of the stage. The fallout engine determines the occurrence of an error, determines the appropriate party/component to remedy the error, and can re-starts the workflow at the point of the error, or before the error.

Abstract: An approach for estimating Round Trip Time (RTT) such as used for estimating a location of mobile User Equipment (UE) devices, particularly adapted for Open Radio Access Networks (O-RANs) that disaggregate basestation functions into a Radio Unit (RU) and a Distributed Unit (DU) or Central Unit (CU). A Positioning Reference Signal (PRS) is transmitted by the RU according to schedule determined by the DU or CU. A Sounding Reference Signal (SRS) is returned by the UE to the DU or CU, with an estimate by the UE of its internal delay. The RU reports an estimate of the difference seen between a time of transmission of the PRS and time of reception of the SRS. The RTT is then estimated by subtracting the UE's internal delay from this difference. RTTs taken between the UE and two or more RU's may further determine a location of the UE.
