Abstract
The present invention provides a method of interference cancellation. Embodiments of the method may include removing one or more first reference signals from a signal received by a first base station to form a modified signal. The signal includes a superposition first reference signal(s) transmitted by first user equipment served by the first base station and one or more second reference signals transmitted by second user equipment served by a second base station. The method may also include extracting the second reference signal(s) from the modified signal and determining a timing delay between the second user equipment and the first base station using the extracted second reference signal(s).
