Disclosed is a method for handling inter-RAT cell measurement in a dual-mode UE in a connected mode, which supports both GSM/GPRS (Global System for Mobile communication/General Packet Radio Service) RAT (Radio Access Technology) and UMTS (Universal Mobile Telecommunications System) RAT. A UTRAN (UMTS Terrestrial Radio Access Network) of the UMTS RAT transmits a measurement control message to a URRC (UMTS Radio Resource Control) of a UMTS network layer in the UE. Upon receiving the measurement control message, the URRC sends a measurement request for GSM cells to an RR/GRR (Radio Resource/GPRS Radio Resource) of a GSM/GPRS network layer. The RR/GRR activates a GSM physical layer and sends a measurement request for the GSM cells to the GSM physical layer. The GSM physical layer performs measurement on the GSM cells and reports a measurement value to the RR/GRR. The RR/GRR reports the measurement value for GSM cells, received from the GSM physical layer, to the URRC. The URRC reports the received measurement value for GSM cells to the UTRAN.

A method for minimizing searching time for a transport format selection in a CDMA communication system including an RLC layer and an MAC layer. The RLC layer entity contains a plurality of logical channels and transmits input data to the MAC layer through a specific logical channel from among the logical channels. The MAC layer contains a plurality of transport channels and transmits the input data to a physical layer through a specific transport channel from among the transport channels. Transport formats are generated for the transport channels, and classified according to sizes of data that can be transmitted by corresponding transport channels. An indicator is provided to each of the transport formats classified according to data size, and a plurality of subset tables are generated. When the data is input to the MAC layer, after the subset tables are generated, a subset table having a same size as the data input to the MAC layer is detected, and a transport format corresponding to a specific indicator is selected.
