Abstract: PURPOSE: A layer 1/2 setting control method of a adaptation tester for a wireless communication terminal is provided to perform a setting control procedure on a layer 1/2 while maintaining merits of a testing procedure language simpler than C language. CONSTITUTION: A user generates setting control information on a required layer 1/2 through a layer 1/2 setting control information generator and stores it in a layer 1/2 setting control information DB(501). A testing procedure language unit checks whether a setting control procedure should be performed on the layer 1/2 in performing a testing procedure(502). If the setting control procedure needs to be performed on the layer 1/2, the testing procedure language unit reads layer 1/2 setting control information on the basis of a fine name from the layer 1/2 setting control information DB(503). The testing procedure language unit transfers the layer 1/2 setting control information to a corresponding layer(504), and checks whether there is a testing procedure to be performed yet(505).

Abstract: PURPOSE: A method for transmitting upward data at a media access control layer of an asynchronous mobile communication terminal is provided to simplify a data transmission process among a PHY layer, an MAC layer, and an RLC layer. CONSTITUTION: An MAC(Media Access Channel) layer receives a MAC setup request primitive(CMAC-CONFIG-REQ) from an RRC(Radio Resource Control) layer(500). The size of data transmittable to a radio bearer corresponding to a set DCH(Data Channel) parameter is initialized as the maximum TF(Transport Format)(501). If the MAC layer receives a transmission synchronization command primitive(TRC-SYNC-CMD) from a PHY(Physical) layer, the size of data transmittable to all radio bearers corresponding to the corresponding transmission channel is set up to transmit data to an RLC(Radio Link Control) layer through an MAC status indicator(MAC-STATUS-IND)(502-504). The MAC layer sets up the size of the TF not exceeding RLC data length as the size of data transmittable to the next TTI(Transmission Time Interval) to the radio bearer received an MAC status response primitive(MAC-STATUS-RES) from the RLC layer(506). The MAC layer returns to wait TRC-SYNC-CMD(507). To the radio bearer received MAC data request primitive(MAC-DATA-REQ) from the RLC layer, an MAC header is added to configure protocol data units and selects a TFI(Transport Format Indicator) fitting to the RLC data length to send physical data request primitive(PHY-DATA-REQ) to the PHY layer(508-510). A TF not exceeding RLC buffer size is sets as the size of the data transmittable to the next TTI(511).
