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).
