Method for controlling retransmission of information using state variables in radio communication system
First Claim
1. A method for transmitting information of a radio link control layer in a radio communication system, the steps comprising:
- transmitting information of the radio link control layer to a receiving device;
determining whether the transmission is successful by checking a response from the receiving device after the information is transmitted; and
comparing a variable indicative of a number of transmissions to a reference value,wherein the comparing step is performed only if it is determined that the transmission was not successful and the transmitting, determining and comparing steps are repeated if the variable is less than the reference value.

Abstract
A method for re-transmitting data or control information in a radio link control layer relates to determining whether re-transmission will be ended by comparing a number of transmission with a critical value when the transmission of data or control information has successively failed. The retransmission cycle is comprised of the steps in the order of transmitting information, checking the transmission failure with exit, and counting the transmission number with exit. Therefore, the present invention makes any transmission be checked and prevents wasting radio resource which can occur in re-transmitting data or control information in UMTS mobile communication system.
