Abstract
A system for providing positioning-related information within wireless communication signals. For example, an apparatus (e.g., acting as a tracker) may receive one or more messages advertising the presence of another apparatus (e.g., acting as a target). The advertisement messages may further comprise information indicating the availability of positioning-related information from the target apparatus. The tracker device may then determine, based on the received information, that positioning-related interaction with the target apparatus is available. If determined to be available, the tracker and target may interact with each other in order to initiate positioning-related information transmission. After receiving at least one message comprising positioning-related information from the target apparatus, the tracker apparatus may then determine at least one of a relative direction towards or from the target apparatus based on the received positioning-related information.
