Abstract:
1. A method for transmitting data packets in a network, wherein the network comprises at least one mobile terminal and at least a first and a second access point, wherein said first and second access points are connected to each other over a link, the method comprising the following steps: selecting, by said first access point, either said first access point or said second access point as a destination for a transmission of an acknowledgment message by one of the at least one mobile terminal, wherein the acknowledgement message indicates a delivery of a data packet at the one of the at least one mobile terminal, and wherein the selection is performed by said first access point on the basis of at least one of a transmission delay on the link and a network coverage of the one of the at least one mobile terminal provided by at least one of the first and second access points, notifying, by said first access point, said one of the at least one mobile terminal whether it has selected the first access point or the second access point as the destination for the transmission of the acknowledgment message, transmitting, by said first access point, a data packet to said one of the at least one mobile terminal, transmitting, by said one of the at least one mobile terminal, the acknowledgment message to the first access point, in the event that the first access point has selected as the destination for the transmission of the acknowledgment message, and transmitting, by said one of the at least one mobile terminal, the acknowledgment message to the second access point, in the event that the first access point has selected the second access point as the destination for the transmission of the acknowledgment message, wherein said first and second access points and said one of the at least one mobile terminal implement a Multi-Radio Unification Protocol, the selection of the one of said first and second access points as the transmission destination of the acknowledgment message is performed within the Multi-Radio Unification Protocol at the first access point, and the selection result is notified to the Media Access Control layer along with the data packet to be transmitted.
