context: were provided by 7 sources out of 14 sources. The performance of relative horizontal accuracy is worse than that of distance accuracy of ranging mainly due to additional angle estimation error. 5 out of 7 sources show Set A can be achieved with at least 100MHz especially for the cases with smaller X values or RSU assist, and 5 out of 7 sources show that Set A cannot be met with 100MHz PRS bandwidth especially for the cases with larger X values or without RSU assist. All 7 sources show Set B cannot be met even by 100MHz in the case without RSU-UE positioning. - The requirement 1.5m@90% (Set A) - is achieved with 20MHz bandwidth in contribution from 1 source ([26]) - X = 25m in contribution from ([26]) where RSU deployment is used for performing relative positioning - is achieved with at least 40MHz bandwidth in contributions from 2 sources ([19], [22]) - X = 20m in contribution from ([22]) - X = 50m in contribution from ([19]) where RSU deployment is additionally used for performing
description: A Roadside Unit (RSU) is a type of device used in Intelligent Transportation Systems (ITS) to provide communication and sensing capabilities for vehicles. In the context of 3GPP TS 38.859, RSUs are used to assist in positioning and ranging for vehicles, particularly in scenarios where precise location information is critical.
explanation: The classification of RSU as a Device is based on its role as a physical entity that provides specific functionalities, such as communication and sensing, to support ITS applications. The context highlights the use of RSUs in conjunction with other technologies to achieve accurate positioning and ranging.
