A receiver, comprising an antenna (ANT UE1 , ANT RX ); a transceiver coupled to the antenna (ANT UE1 , ANT RX ), the transceiver configured to receive from a transmitter of a wireless communication network a data block, the data block including encoded data transmitted on a plurality of resources allocated to the receiver; a decoder configured to decode the encoded data and to determine for the allocated resources whether decoding of the encoded data was successful or failed; and a processor configured to evaluate whether one or more of the resources for which the decoding failed are included in a report provided by the transmitter, the report indicating for one or more of the allocated resources that encoded data transmitted on the one or more allocated resources is not decodable or is likely to be not decodable, and to cause the transceiver to send a retransmission request to the transmitter responsive to the evaluation, wherein the report indicates for the one or more resources a probability that encoded data is not decodable, characterized in that the report associates the allocated resources with a plurality of pollution levels, a pollution level depending of the probability that encoded data transmitted on the allocated resource is not decodable, wherein the probability depends on the impairments the one or more resources experience and originating from the transmitter and/or one or more further entities of the wireless communication network. an antenna (ANT UE1 , ANT RX ); a transceiver coupled to the antenna (ANT UE1 , ANT RX ), the transceiver configured to receive from a transmitter of a wireless communication network a data block, the data block including encoded data transmitted on a plurality of resources allocated to the receiver; a decoder configured to decode the encoded data and to determine for the allocated resources whether decoding of the encoded data was successful or failed; and a processor configured to evaluate whether one or more of the resources for which the decoding failed are included in a report provided by the transmitter, the report indicating for one or more of the allocated resources that encoded data transmitted on the one or more allocated resources is not decodable or is likely to be not decodable, and to cause the transceiver to send a retransmission request to the transmitter responsive to the evaluation, to evaluate whether one or more of the resources for which the decoding failed are included in a report provided by the transmitter, the report indicating for one or more of the allocated resources that encoded data transmitted on the one or more allocated resources is not decodable or is likely to be not decodable, and to cause the transceiver to send a retransmission request to the transmitter responsive to the evaluation, wherein the report indicates for the one or more resources a probability that encoded data is not decodable, characterized in that the report associates the allocated resources with a plurality of pollution levels, a pollution level depending of the probability that encoded data transmitted on the allocated resource is not decodable, wherein the probability depends on the impairments the one or more resources experience and originating from the transmitter and/or one or more further entities of the wireless communication network. <EOS>
