Abstract: PURPOSE: A method for receiving an RLP frame in consideration of a radio environment is provided to receive entire data quickly and accurately without an error by re-transmitting error-generated data in consideration of a radio environment. CONSTITUTION: When a mobile terminal or a base station of one mobile communication system transmits frame data according to an RLP protocol, a channel is allocated and a call is established through the allocated channel(S200). A state variable is initialized and a data transfer rate and L2R are activated by communicating with the other mobile communication system(S210). An exchange parameter is negotiated and set to a certain value(S220). The one mobile communication system receives RLP frame data sequentially according to a corresponding order(S230) and determines whether all of them are completely received(S240). If some RLP frame data has not been received, a receiving side measures a BER(Bit Error Rate) to measure a degree of data loss(S250) and determines whether the degree of the data loss is greater than a pre-set reference value(S260). If the degree of the data loss is smaller than the pre-set reference value, the receiving side requests re-transmission of the corresponding frame data by using the previously set exchange variable(S280). It is determined whether the re-transmission-requested data has been successfully received(S290).
