Abstract  Abstract

The invention claims a method for reducing technique of the retransmission packet. one or more acknowledgement (ACK) one is configured for double-connection main evolved node B (HeNB) from a user equipment (UE) receiving an indication at the UE successfully from the auxiliary evolved Node-B (SeNB) of the received packet. ;MUE can be received for packet transmission information of the SeNB from the SeNB. ;MUE can receive indication of lost about the air interface connection between the SeNB and the UE from the SeNB. ;MUE can be partially based on the ACK received from the UE and the packet transmission information received from the SeNB to identify is not transmitted to remaining packets of the UE from the SeNB but has not been sent to the UE due to a loss of connection between the SeNB and the UE wherein the remaining packets. ;MUE can be the remaining packets sent from the HeNB to the UE.

Technology for reducing packet transmissions is disclosed. A master evolved node B (MeNB) configured for dual connectivity can receive one or more acknowledgements (ACKs) from a user equipment (UE) indicating packets that were successfully received at the UE from a secondary evolved node B (SeNB). The MeNB can receive from the SeNB packet delivery information for the SeNB. The MeNB can receive an indication from the SeNB of an air-interface connection loss between the SeNB and the UE. The MeNB can identify remaining packets that were not sent from the SeNB to the UE based in part on the ACKs received from the UE and the packet delivery information received from the SeNB wherein the remaining packets are not sent to the UE due to the connection loss between the SeNB and the UE. The MeNB can send the remaining packets from the MeNB to the UE.
