Abstract: A wireless communication device includes circuitry and capability to perform carrier frequency offset (CFO) estimation based on signals received from one or more other wireless communication devices. In an orthogonal frequency division multiple access (OFDMA) implementation, the wireless communication device receives two or more OFDMA symbols from first and second other wireless communication devices that include data and a copy/repeat of that data from each of the respective first and second other wireless communication devices within specified one or more sub-carriers. The sub-carrier assignment for the first and second other wireless communication devices is made such that the first wireless communication device transmits first data and the copy of that first data using a first at least one sub-carrier, and the second wireless communication device transmits second data and the copy of that second data using a second at least one sub-carrier.
