Patent ID: 8654728

Claim:
A method in at least one network node which provides wireless communications service for user equipment nodes, UEs, the method comprising: detecting uplink interference at an interfered network node; initiating an uplink transmission by a UE, which is served by a serving network node, of an uplink signal having a defined configuration, responsive to the uplink interference, wherein initiating the uplink transmission by the UE of the uplink signal having the defined configuration comprises: communicating, from the interfered network node to the serving network node, an indication of the uplink interference; determining the defined configuration at the serving network node responsive to the indication of the uplink interference; communicating to the interfered network node an uplink configuration message that identifies the defined configuration of the uplink signal to be transmitted by the UE; and controlling the UE from the serving network node in response to the defined configuration to cause transmission of the uplink signal with the defined configuration; detecting the uplink signal using the defined configuration at the interfered network node; identifying the UE responsive to the detected uplink signal as being a contributor to the uplink interference; and controlling uplink transmission by the UE and/or by another UE served by the serving network node to reduce uplink interference.
