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.
Claims30
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.
A method of receiving a radio link protocol frame, comprising:
- receiving data including a radio link protocol frame;
- discriminating an error frame from said received data;
- varying at least one exchange identification parameter based on a comparison result;
- and
- requesting retransmission of said error frame using said at least one varied exchange identification parameter.
A mobile terminal receiver, comprising:
- an antenna receiving data;
- and
- a controller which varies at least one exchange identification parameter used for transmitting a radio link protocol frame based on a degree of loss of a previously received radio link protocol frame.
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.
