Abstract
A mobile terminal determines that it is operating in a range-expansion region and performs interference cancellation techniques that are particularly advantageous in the range-expansion region. An example method of receiving a target link signal at a receiving device, where the target link signal is received in a received signal that also includes an interfering link signal, thus includes determining (510) that the receiving device is operating in a range-expansion region of a low-power node in a heterogeneous network deployment, based on a serving-cell geometry metric or a dominant-interferer ratio metric or both. The method further includes configuring (520) the receiving device to perform interference cancellation, responsive to determining that the receiving device is operating in a range-expansion region. The example method continues with performing (530) the configured interference cancellation on the interfering link signal, and then demodulating and decoding (540) the target link signal.
