Abstract

A technique is provided for retransmitting data in a dual connectivity network in which a mobile station (MS) is connected to a first base station (BS) via a first radio link and to a second BS via a second radio link, including sending, by a first protocol entity of the MS, a protocol data unit (PDU) to a first entity of a second protocol of the MS for transmission to the first BS via the first radio link, detecting a trigger condition at the MS associated with the PDU, and re-sending, by the first protocol entity of the MS, the PDU to a second entity of the second protocol of the MS for transmission to the second BS via the second radio link.
