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.
