The disclosure relates to a method in a macro base station of a heterogeneous wireless communication system, for reducing uplink interference at a radio base station with restricted wireless access. The uplink interference is caused by a user equipment served by the network node, which has a restricted wireless access to the radio base station. The method comprises receiving (310) measurement reports from user equipments served by the network node, and identifying (320) a user equipment causing uplink interference at the radio base station among the user equipments, based on the received measurement reports. The method also comprises obtaining (330) information relating to a total uplink received interference from the radio base station via the identified user equipment, and adjusting (340) a transmit power, a transmission activity, and/or a scheduling of the identified user equipment based on the obtained information, such that the uplink interference caused by the identified user equipment is reduced. |
