1. A method in a network comprises:
transmitting, by a first radio link control (RLC) entity, a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU) or segment of a PDCP PDU on a first link;
transmitting, by a second RLC entity, the PDCP PDU or the segment of the PDCP PDU on a second link, wherein the second RLC entity is associated with the second link;
receiving, from a receiver and at the first RLC entity, a positive acknowledgement indicating a successful receipt of the PDCP PDU or the segment of the PDCP PDU on the first link;
transmitting, by the first RLC entity an indication to a PDCP entity that the PDCP PDU or segment of the PDCP PDU was received by the receiver;
communicating, via a backhaul channel, an indication to the second RLC entity to discard the PDCP PDU or segment of the PDCP PDU; and
cancelling one or more retransmissions of the PDCP PDU or the segment of the PDCP PDU on the second link.
