Abstract
An interference problem for UE retransmissions at the end of a Sequence Frame Number pattern, in a system wherein a macro base station () employs Almost Blank Subframes (ABS) to avoid interference with a micro base station (), is avoided by first recognizing that an ABS pattern will reset at the end of a SFN period. In some embodiments, in response to this recognition, the micro base station () may command () a UE to alter a transmission to the micro base station (), to improve the probability of accurate reception—such as by increasing its transmit power during the relevant time slots, or utilizing a more robust data correction encoding scheme. In other embodiments, in response to recognizing the change in the ABS pattern, the macro base station () may schedule () other UE to a PRB where they cause lower interference, or may avoid scheduling macro cell UEs in the same time slot.
