A relay device for relaying a data packet to be transmitted from a first partner transceiver to a second partner transceiver

摘要

A relay apparatus (100) for relaying a data packet to be transmitted from a first partner transceiver to a second partner transceiver comprising a receive unit (110) for receiving the data packet and for receiving an acknowledgement packet to be transmitted from the second partner transceiver to the first partner transceiver when the second partner transceiver has successfully received the data packet. The relay apparatus (100) further comprising a help detector (120) for providing a help indicator if a help required situation is detected and a transmit unit (130) for transmitting the data packet in response to the help indicator. The help required situation is detected based on whether a first communication link between the relay apparatus (100) and the second partner transceiver is better than a second communication link between the first and second partner transceivers, the second communication link being evaluated by an information being available from the data packet.
