Abstract:
A method is disclosed that can be performed in at least one network node which provides wireless communications service for user equipment nodes (UEs). The method includes detecting uplink interference at an interfered network node. Responsive to the uplink interference, an uplink transmission having a defined configuration is initiated from a UE, which is served by a serving network node. The uplink signal is detected using the defined configuration at the interfered network node. The UE is identified responsive to the detected uplink signal as being a contributor to the uplink interference. An uplink transmission by the UE and/or by another UE served by the serving network node is controlled to reduce uplink interference.
