摘要： A method for sending a data packet from a base station to a mobile terminal includes signalling to the mobile terminal in a first subframe of a radio channel a first downlink assignment of a first data packet of a bundling window. The bundling window represents a number of data packets, already transmitted or to be transmitted to the mobile terminal, that are to be confirmed by the mobile terminal. The downlink assignment represents information about a minimum total number of data packets within the bundling window that are scheduled to be transmitted to the mobile terminal. The method also includes transmitting data packets from a base station in subframes of the radio channel using the bundling window.
