Abstract: Implementations described and claimed herein provide systems and methods for correlating one or more service areas of a network with one or more geolocation coordinates to determine available services for customers to the network. A service polygon may be generated that define an area in which a particular service offered by a communications network is available. The boundaries of the service polygons may be adjusted based on information corresponding to physical features of the initial area. The service polygons may aid a communications network in providing a list of available services to potential customers or devices connected to the network by determining one or more geolocation coordinate values of a potential connection site and comparing the values to the service polygons. A network management system may determine the available services, current or in the future, to offer such services to a customer to the network.

Abstract: Techniques described herein provide for the efficient usage of an RF channel for PRS transmissions by performing LBT sensing for a group of one or more vehicles (e.g., V2X vehicles) in a predetermined area by using an RSU. The RSU can determine a sequence in which an order for each vehicle in the group to transmit a respective PRS is defined, and provide the sequence to the group. The RSU may further perform the LBT functionality by listening to availability on the RF channel and, when the channel becomes available, the RSU can initiate this sequence by sending an initial PRS. This LBT sensing for a group can provide far more efficient usage of the RF channel than if LBT functionality were performed by each divisional vehicle.
