Abstract:
1. A method of performing a measuring procedure in a wireless communication system, the method comprising: transmitting Carrier Aggregation (CA) measurement capability information to a network; transferring data using a plurality of different frequencies; and receiving a measurement command from the network, wherein the measurement command includes at least one specific frequency to be measured during a time interval, wherein the measurement command further includes frequency information indicating a termination of the transferring of data during the time interval, and wherein the frequency information is related with at least one of the plurality of different frequencies; performing measurement of the at least one specific frequency during the time interval; and transmitting a measurement report based on the performed measurement, wherein, if a specific frequency set for a terminal matches with a frequency that should be measured and if there are any transmitter or receiver circuits, which are not currently used to communicate with the network, that support the frequency that should be measured, data is transferred to the network using frequencies of the plurality of different frequencies other than the at least one specific frequency while the measurement of the at least one specific frequency is performed, wherein the CA measurement capability information is for determining whether the specific frequency set for the terminal matches with the frequency that should be measured and for determining whether there are any transmitter or receiver circuits that support the frequency that should be measured, and wherein transmitting the CA measurement capability information, transferring the data, receiving the measurement command, performing the measurement of the at least one specific frequency and transmitting the measurement report are performed in a LTE-A (Long-Term Evolution Advanced) system that supports a CA scheme.
