Abstract
Radio Link Control ACK/NACK is conditionally suppressed. A first wireless communications device including a radio transmitter identifies a first packet flow for which end to end packet retransmission is supported. The first wireless communications device identifies a Packet Data Convergence Protocol (PDCP) packet corresponding to Radio Link Control Acknowledged Mode (RLC AM), said identified packet being included in the identified first packet flow. The first wireless communications device generates an Acknowledged Mode Protocol Data Unit (AM PDU) including a No RLC ACK Required (NRAR) indicator set to indicate RLC ACK is not required, and the radio transmitter in the first wireless communications device transmits the AM PDU, e.g., an AMD PDU, to a second wireless communications device. The second wireless communications device receives the transmitted AM PDU, recovers the NRAR indicator value, and based on the communicated value of the NRAR indicator, determines to suppress RLC ACK/NACK.
