Abstract

A receiver includes an antenna, a transceiver coupled to the antenna, a decoder and a processor. The transceiver receives from a transmitter of a wireless communication network a data block. The data block includes encoded data transmitted on a plurality of resources allocated to the receiver. The decoder decodes the encoded data and determines for the allocated resources whether decoding of the encoded data was successful or failed. The processor evaluates whether one or more of the resources for which the decoding failed are included in a report, 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 causes the transceiver to send a retransmission request to the transmitter responsive to the evaluation.
