Method and apparatus in a communication unit employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received receive (RX) sub-frames, in transmit (TX) sub-frames available for transmission. An obtaining unit in the communication unit receives allocation parameters for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit in the communication unit then schedules feedback reports in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.
