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: Methods, apparatuses, and systems for improved channel estimation in an Orthogonal Frequency Division Multiplexing (OFDM) system are discussed. In one example discussed herein, joint two-dimensional Minimum Mean-Square Error (2D-MMSE) channel estimation is performed on any Resource Element (REs) containing a reference signal in a Resource Block (RB), one-dimensional Minimum Mean-Square Error (1D-MMSE) channel estimation is performed in the frequency domain on each OFDM symbol in the RB, and then channel estimation is performed in the time domain on each frequency sub-carrier in the RB. In another example discussed herein, Power Delay Profiles (PDPs) and/or frequency correlations are calculated using minimax optimization and then stored in a Look-Up Table (LUT) indexed by estimated Signal to Noise Ratio (SNR) and the estimated maximum delay spread. A portable device could use such an LUT in MMSE calculations.
