Abstract: An interference problem for UE retransmissions at the end of a Sequence Frame Number pattern, in a system wherein a macro base station (12) employs Almost Blank Subframes (ABS) to avoid interference with a micro base station (16), 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 (16) may command (108) a UE to alter a transmission to the micro base station (12), 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 (12) may schedule (208) other UE to a PRB where they cause lower interference, or may avoid scheduling macro cell UEs in the same time slot.

Abstract: A base station (BS) and method for controlling handover in a wireless communication system. The BS serves a first cell in a first cell layer overlapping with a second cell layer, and the first cell has a different distribution of configured amounts of uplink and downlink resources than a second cell in the second cell layer. The BS monitors amounts of uplink and downlink resources utilized by a user equipment (UE) in the first cell and adjusts at least one parameter controlling handover of the UE to the second cell based on the resources utilized by the UE, and on information regarding configured amounts of uplink and downlink resources in the first and second cells. This increases the likelihood that the UE will be served by one of the first and second cells in which the configured amounts of resources better matches the amounts of resources utilized by the UE.
