Multi-Path Mitigation in Rangefinding and Tracking Objects Using Reduced Attenuation RF Technology
First Claim
1. A method for determining a location of one or more user equipment (UE) in a wireless system, the method comprising:
- determining that positioning reference signals are available for use in a first mode of operation;
determining that non-positioning specific reference signals are available for use in a second mode of operation;
selecting the first mode of operation, the second mode of operation, or a combination of the first mode of operation and the second mode of operation as a mode of operation of the wireless system based on network parameters; and
utilizing the selected mode of operation to calculate a location of each UE among the one or more UE.

Abstract
An autonomous system with no Customer Network Investment is described, wherein the system is configurable to operate on a band other than the LTE band. Such system allows the definition of hybrid operations to accommodate the positioning reference signals (PRS) of LTE and already existing reference signals. The system can operate with PRS, with other reference signals such as cell-specific reference signals (CRS), or with both signal types. As such, the system provides the advantage of allowing network operator(s) to dynamically choose between modes of operation depending on circumstances, such as network throughput and compatibility.
