<p>In a communication system, activity of a transmitter (10), e.g., a UE, is controlled in response to a deactivation command (401). The transmitter (10) receives data on at least one transmission carrier and, if a received transmission of data is found to be defective, may send a repeat request to trigger a retransmission (404) of the data. In response to receiving the deactivation command (401), the transmitter (10) performs a check whether a retransmission (404) is expected on the at least one transmission carrier. If a retransmission (404) is expected, execution of the deactivation command (401) to deactivate the transmission carrier is delayed until the retransmission (404) is received or a timer has expired.</p> |
