A method for Adjusting Transmitting window in a Radio Link Control Layer

摘要

The present invention relates to a method for adjusting transmitting window in a radio link control layer. Basic idea is that the RLC transmitting party controls the use of bandwidth in radio link by deciding periodically whether a size of transmitting window needs to be adjusted, and adjusting the size of transmitting window in the RLC transmitting party if the use efficiency of bandwidth is decreased. By employing the present invention, the RLC transmitting party can decide the use of bandwidth of the link according to its own state variables but not depending on Window Size SUFI information transmitted by the RLC receiving party, and then adjust the size of transmitting window. In such way, the defect that the transmitting window is unable to be adjusted timely when Window Size SUFI information is lost can be avoided, and the transmitting window can be adjusted promptly, approaching the aim of utilizing radio bandwidth fully and most efficiently.
