Abstract
Embodiments of the disclosure relate to determining location of client devices in a distributed antenna system (DAS) based on detecting uplink received power. In this regard, a client device location system is provided in the DAS to configure each remote unit in the DAS to generate a power-regulated UL communications signal based on an assigned power pattern. If a respective power pattern of a reference signal(s) uniquely identifying a client device corresponds to the assigned power pattern of the remote unit that generates the power-regulated UL communications signal, the client device location system reports the location of the remote unit as the location of the client device in the DAS. Hence, it is possible to locate the client device based on the location of the remote unit, thus providing the location of the client device with higher degree of accuracy.
