ENHANCED PASSIVE POSITIONING WITH ADAPTIVE ACTIVE POSITIONING

摘要

Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations and/or techniques for enhanced passive positioning with adaptive round trip time (RTT)-type ranging, such as for use in or with a mobile communication device, for example.

主权项

1. A method at mobile device, comprising:
obtaining passive measurements of signals transmitted from terrestrial transmitters; obtaining a first estimated location of said mobile device based, at least in part, on said passive measurements; and initiating active measurements for obtaining a second estimated location of said mobile device in response to determining that said first estimated location is not of sufficient quality based, at least in part, on said first estimated location and a spatial configuration of said terrestrial transmitters.
