Radio link control cumulative mode for new radio

A base station, comprising:

• a transceiver configured to communicate with a user equipment (UE);
• and
• a processor communicatively coupled to the transceiver and configured to:
• transmit multiple transmission control protocol (TCP) packets to the UE;
• receive, from the UE, a first cumulative acknowledgement (ACK) comprising ACKs for each of the multiple TCP packets and a header, wherein the cumulative ACK is received in a radio link control (RLC) protocol data unit (PDU) via a RLC cumulative mode (CM) bearer;
• start a timer upon receiving the first cumulative ACK;
• and
• determine whether a second cumulative ACK was received prior to an expiration of the timer.
