Abstract
A method is performed by a wireless device for transmitting PDCP packets over a multi-hop path to a receiver, in accordance with particular embodiments. The method begins with receiving PDCP signalling indicating that at least one transmitted PDCP packet has not been received. For example, the PDCP signalling may comprise a PDCP status PDU, or may comprise PDCP data recovery or PDCP re-establishment RRC signalling. In response to receiving the PDCP signalling indicating that at least one transmitted PDCP packet has not been received, the wireless device retransmits the at least one transmitted PDCP packet that has not been received, even if said transmitted PDCP packet has been acknowledged by a lower protocol layer. A method is also performed by a network node in accordance with particular embodiments.
