Methods and radio network nodes for measuring interference
A first radio network node for measuring interference between the first radio network node and a second radio network node obtains configuration information that indicates which subframe is a flexible subframe in which a reference signal for measurement of the interference is to be transmitted by the second radio network node. The first radio network node determines whether to configure the flexible subframe as an uplink subframe based on a necessity of the measuring of interference between the first radio network node and the second radio network node. The first radio network node configures the flexible subframe as an uplink subframe when the measuring of interference is needed, and receives the reference signal for measurement of the interference from the second radio network node in the uplink subframe.
