A method is described which includes allocating transmission resources for transmitting data packets. The allocation of transmission resources includes a periodic allocation of the transmission resources that is applicable to a plurality of frames. The allocation of transmission resources includes an allocation of transmission resources for a first transmission of each HARQ process during the plurality of frames. The method includes receiving an indication of an allocation of transmission resources for data packets in a plurality of frames. Receiving and/or transmitting packets during the plurality of frames using the allocation of transmission resources is also included in the method. The frames in the plurality of frames may include a compressed MAC header. Apparatus and computer programs are also described.
