System and method for prioritization of retransmission of protocol data units to assist radio link control retransmission

摘要

A network device or user equipment (UE) may manage the transmission and retransmission of radio link control (RLC) data protocol data units (PDUs). An indication is received that an RLC data PDU was not successfully received by a receiving device. The RLC data PDU, that was not successfully received, is retransmitted, and prioritized over non-retransmitted RLC data PDUs. A number of times that the RLC data PDU was retransmitted is determined.

主权项

1. A network device characterized in that:
circuitry is configured to provide a radio link control (RLC) data protocol data unit (PDU); the circuitry is further configured to receive an indication that the RLC data PDU was not successfully received; and wherein on a condition that the RLC data PDU was not successfully received:
the circuitry is further configured to retransmit the RLC data PDU and to prioritize the retransmitted RLC data PDU over non-retransmitted RLC data PDUs; and the network device is configured to determine a number of times that the RLC data PDU was retransmitted.
