Abstract:
Systems and methods for determining a location of a wireless device are disclosed. In one embodiment, a method of operation of a central processing node for a shared cell of a cellular communications network includes obtaining signal strength measurements for a signal received from a wireless device at multiple Reception/Transmission (R/T) points in the shared cell. The signal strength measurements are simultaneous signal strength measurements made on signal discrimination space resources in an uplink of the shared cell. Further, the signal discrimination space resources are matched to capabilities of power meters utilized to generate the signal strength measurements. The method further includes identifying one or more of the R/T points having the best signal strength measurements and estimating a location of the wireless device based on known locations of the identified R/T point(s).
