Abstract:
The invention is directed to systems, methods and computer program products for determining a location of a device on a massive MIMO (multiple-input multiple-output) network. The device transmits a signal comprising several multipath components (MPCs) either omnidirectionally or with limited directivity. The method comprising identifying, by a base station, that receives MPCs, an MPC with a figure of merit, based on a time delay and an angular spread, better than that of other MPCs; determining, by the base station, an angle of arrival (AoA) of the MPC is different from the AoAs of the other MPCs; and determining, by the base station, a location of the device based on the time delay and the AoA.
