Abstract: Disclosed is a method of transmitting a message for measuring a distance between a first terminal and a second terminal that are positioned in a basic service set (BSS), and in this case, the first terminal transmits a fine timing measurement (FTM) request frame for beginning of measurement of a distance to second terminal. The first terminal receives an Ack frame for the FTM request frame from the second terminal. The first terminal transmits a first data frame to the second terminal, by the first terminal. The first terminal receives a first Ack frame for the first data frame from the second terminal, by the first terminal. The first terminal transmits a second data frame but not the FTM frame to the second terminal. The first terminal receives a second Ack frame for the second data frame from the second terminal.

Abstract: A system and method for characterizing an interference demodulation reference signal (DMRS) in a piece of user equipment (UE), e.g., a mobile device. The UE determines whether the serving signal is transmitted in a DMRS-based transmission mode; if it is, the UE cancels the serving DMRS from the received signal; otherwise the UE cancels the serving data signal from the received signal. The remaining signal is then analyzed for the amount of power it has in each of four interference DMRS candidates, and hypothesis testing is performed to determine whether interference DMRS is present in the signal, and, if so, to determine the rank of the interference DMRS, and the port and scrambling identity of each of the interference DMRS layers.
