1. A processor of a user equipment (UE) configured to perform operations comprising:
receiving a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time;
storing the first cumulative ACK in a queue;
receiving a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time;
storing the second cumulative ACK in the queue;
discarding the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK; and
encapsulating the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.
