Apparatus, system or method to improve communications in a wireless communication network. Steps may include sending specific information to user equipment or adjacent base stations so that the user equipment and adjacent base stations can determine interference levels in sidelink communications. The apparatus may include a location-estimation component interconnected with a self-tracking component and a signal-detection component. The apparatus may include a proximity system implemented using instructions stored in a non-transitory computer readable medium and the proximity system may be usable to locate one or more target transmitters. In some embodiments, the system may include other modules such as a localization module; a proximity-description module; and a proximity-display module. The proximity system may also include a proximity advertisement module, which includes an access management component; an ownership management component; and a content management component.
