Abstract
A base station of a time reversal communication system is provided. The base station receives a set of channel probing signals from a set of terminal devices, determines channel impulse responses based on the channel probing signals, and determines location-specific signature waveforms based on the channel impulse responses, in which each of the location-specific signature waveforms is associated with a particular location of the respective terminal device. The base station generates a set of medium access layer parameters, in which each medium access layer parameter is associated with a particular one of the terminal devices. For each terminal device, the base station generates transmit data signals based on data intended for the terminal device, and the medium access layer parameter and the location-specific signature waveform associated with the terminal device. The base station transmits the transmit data signals wirelessly to the terminal devices.
