Abstract: A method and apparatus for enhancing data retransmission to improve call performance are described. At least one protocol data unit (PDU) may be transmitted from a transmitting entity to a receiving entity. The at least one PDU may be part of a service data unit (SDU). It may be determined to perform a communication re-establishment. As such, the SDU may be retransmitted, beginning with a first PDU transmitted as part of the SDU. In an aspect, the transmitting entity may be a radio link control (RLC) transmitting device and the receiving entity may be an RLC receiving device in communication with one another across a network. In another aspect, the transmitting entity may be a radio link control (RLC) transmitting protocol layer and the receiving entity may be a radio link control (RLC) receiving protocol layer both within a protocol stack of a device.

Abstract translation: 描述了用于增强数据重传以改善呼叫性能的方法和装置。 至少一个协议数据单元（PDU）可以从发送实体发送到接收实体。 所述至少一个PDU可以是服务数据单元（SDU）的一部分。 可以确定执行通信重建。 这样，可以从作为SDU的一部分发送的第一PDU开始重传SDU。 在一方面，发送实体可以是无线电链路控制（RLC）发送设备，并且接收实体可以是通过网络彼此通信的RLC接收设备。 在另一方面，发送实体可以是无线电链路控制（RLC）发送协议层，并且接收实体可以是设备的协议栈内的无线电链路控制（RLC）接收协议层。
