First Claim
Patent Images
1. An RLP (Radio Link Protocol) frame receiving method, comprising:
- discriminating an error frame from received RLP frames;
measuring a degree of loss of the received RLP frame and comparing the measured degree of loss with a reference value when an error frame is detected;
varying XID (Exchange Identification) parameters set at an initial stage of reception on the basis of a comparison result; and
requesting retransmission of an RLP frame corresponding to the error frame on the basis of the varied XID parameters.

Abstract
An RLP (Radio Link Protocol) frame receiving method transmits an RLP frame entirely and quickly in consideration of a radio environment in a mobile communication system. The method discriminates an error frame from the received RLP frame, measures a degree of loss of the received RLP frame and compares the measured degree of loss with a reference value when the error frame is detected. XID parameters (Exchange Identification Parameters) set during an initial stage of reception are varied on the basis of a comparison result and retransmission is then requested of the RLP frame corresponding to the error frame on the basis of the varied XID parameters.

23. A method for controlling data transmission in a mobile communication system, comprising:
-
receiving a number of radio link protocol frames; determining existence of an error frame in the received radio link protocol frames cause by an adverse radio environment; adjusting an exchange identification parameter based on detection of the error frame; and requesting retransmission of at least the error frame using the adjusted exchange identification parameter. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
