Abstract:
A method for blindly determining positioning reference signals in a wireless communication network determines a positioning reference signal (PRS) network configuration by estimating a PRS energy from predetermined locations of each subframe of an incoming signal. Such a method may also include blindly detecting PRS parameters based on the estimated PRS energy. The PRS energy may be peak energy responses for deep searches or verifications. The PRS energy may be a signal to signal plus noise ratio for shallow searches.
