	abstract = {User location privacy is a growing concern in cellular networks.~It has been recently shown that the paging architecture in GSM~networks leaks user location information. In this paper, we first prove~theoretically that LTE networks also have the same vulnerability. We~then propose a solution making use of a novel signal processing technique,~physical layer identification. The idea is to embed users{\textquoteright} unique~tags onto the downlink paging signal waveforms so that the tags are ~stealthy and robust. We show that our scheme not only improves users{\textquoteright}~privacy, but also saves system bandwidth.},
