Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded.
