Abstract: A method can include determining that a received signal traveled via a shortest path from a transmitting device to a receiving device of an orthogonal frequency-divisional multiplexing (OFDM) communication system, determining a phase rotation of the received signal, and determining a time of arrival based on the determined phase rotation.

Abstract: According to an example implementation, a method for frequency offset reporting includes transmitting, by a first transceiver, a first tracking reference signal to a user device in a wireless communication system, transmitting, by a second transceiver, a second tracking reference signal to the user device, receiving, by the base station, a channel state information (CSI) reporting signal via an uplink channel, where the CSI reporting signal includes power estimation information. The method includes determining whether to pre-compensate a frequency of a downlink signal with frequency offset information based on the power estimation information, and transmitting, by at least one of the first transceiver or the second transceiver, the downlink signal with the pre-compensated frequency in response to the determination to pre-compensate the frequency of the downlink signal.
