Method and apparatus for enhancing data retransmission to improve call performance

摘要

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.

1. A method for wireless communication, comprising:
transmitting at least one protocol data unit (PDU) from a transmitting entity to a receiving entity, wherein the at least one PDU is part of a service data unit (SDU); determining to perform a communication re-establishment; in response to determining to perform the communication re-establishment,
transmitting a move receive window (MRW) command to the receiving entity;receiving an MRW command acknowledgment from the receiving entity indicating that the receiving entity has discarded the SDU and has moved a receive window in preparation for receiving a retransmitted SDU; andretransmitting the SDU, beginning with a first PDU transmitted as part of the SDU.
