Abstract
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.

16. A method for controlling activity of a user equipment in a communication system with repeat requests, the user equipment being adapted to receive data on at least one transmission carrier, the method comprising:
-
the user equipment receiving a deactivation command for deactivation of the at least one transmission carrier; in response to the deactivation command, the user equipment performing a check whether a retransmission is expected on the at least one transmission carrier; and if a retransmission is expected, delaying execution of the deactivation command until the retransmission is received or a timer has expired. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A user equipment, comprising:
-
a receiver unit adapted to receive transmissions of data, retransmissions, and deactivation commands; a transmitter unit adapted to send repeat requests; and a processor adapted to control deactivation of transmission carriers by executing a received deactivation command for deactivation of at least one transmission carrier used by the receiver unit to receive the transmissions of data, wherein the processor is further adapted to perform a check whether a retransmission is expected on the at least one transmission carrier and, if a retransmission is expected, delay execution of the deactivation command until the retransmission is received or a timer has expired. - View Dependent Claims (27, 28, 29)

30. A communication system, comprising:
-
a user equipment; and a base station, wherein the base station is adapted to send transmissions of data, retransmissions, and deactivation commands to the transmitter; wherein the user equipment is adapted to receive the transmissions of data, the retransmissions, and the deactivation commands from the base station and to send repeat requests to the base station to trigger the retransmissions; and wherein the user equipment is further adapted to control deactivation of transmission carriers by executing a received deactivation command for deactivation of at least one transmission carrier used to receive the transmissions of data, and wherein the user equipment is further adapted to perform a check whether a retransmission is expected on the at least one transmission carrier and, if a retransmission is expected, delay execution of the deactivation command until the retransmission is received or a timer has expired.
