The invention concerns a method of managing coexisting packet streams ( 100, 110 ) in a wireless communication system, and a corresponding controller and a mobile terminal. A first packet stream ( 110 ) of the coexisting packet streams ( 100, 110 ) requires transmission resources of the wireless communication system at fixed time intervals, and a second packet stream ( 100 ) of the coexisting packet streams ( 100, 110 ) requires transmission resources of the wireless communication system at dynamically determined time intervals. A schedule defining allocations of transmission resources for the first packet stream ( 110 ) is set up. A request for an initial grant of transmission resources for a transmission of a data packet ( 101 ) of the second packet stream ( 100 ) is issued. In the process of allocating transmission resources to the second packet stream ( 100 ), the controller analyses the schedule of transmission resources allocated to the first packet stream ( 110 ) and thereby determines whether a retransmission ( 102, 103 ) of the data packet ( 101 ) associated with the second packet stream ( 100 ) is possible to collide with a transmission of a data packet ( 111, 112 ) associated with the first packet stream ( 110 ) according to the schedule. The controller transmits a parameter specifying a number N of retransmissions ( 102, 103 ) possible without such collision as part of the initial grant of transmission resources to the mobile terminal.
