According to an aspect, there is provided an apparatus for a radio receiver or transceiver of a first access node. The apparatus is configured to perform the following. Upon receiving data via at least one antenna, the apparatus performs resource mapping on the received data based on scheduling information defining currently allocated uplink time-frequency resources to isolate at least a first data set corresponding to non-allocated uplink time-frequency resources. The apparatus compares the first data set against one or more first pre-defined criteria for detecting interference. In response to detecting interference in the first data set according to said one or more first pre-defined criteria, the apparatus instructs a scheduler entity of the first access node to avoid scheduling uplink time-frequency resources affected by said interference.
