Abstract:
In a communication system (100) where a wireless relay node (RN) (114) relays data packets between a Node B (112) and a user equipment (UE) (102), the RN receives (608) a data packet from the Node B via a first wireless link (115), conveys (614) the received data packet to the UE via a second wireless link (120), determines (616) whether the UE is likely to handoff, and in response to determining that the UE is likely to handoff, delays conveying (620, 622) an acknowledgment of the data packet to the Node B until an acknowledgment has been received from the UE. In another embodiment, the RN may use a status report (720) to inform the Node B of data packets that have not been transmitted to the UE or that have been transmitted to the UE but for which an acknowledgement has not been received from the UE.
