Abstract:
The claimed subject matter relates to systems and methodologies for synchronizing timing between a base station and a wireless terminal. For example, a set of non-contiguous tones may be assigned to the terminal, and may be equally spaced apart from each other across a spectrum of all available tones. A set of contiguous tones may also be assigned to the terminal, which may transmit a timing control signal during a specified transmit time. A base station may receive the signal, which comprises information related to the non-contiguous and contiguous tone sets, and may determine a distance of the terminal to the base station based on measured and anticipated arrival time of the signal. The base station may transmit a timing correction command signal to the terminal based on such information.
