and determining whether to configure a measurement gap to at least one of the component carriers, according to the component carrier capability indicating the maximum number of the component carriers and a first number of component carriers that have been configured to the mobile device. ### Claim 2 (depends on 1) The method of claim 1 further comprising: determining that a change of the component carrier capability occurs, when transmission of a multimedia broadcast multicast service (MBMS) message is activated on one of the component carriers and the component carrier for the transmission of the MBMS message is a component carrier only dedicated to the transmission of the MBMS message. ### Claim 3 (depends on 2) The method of claim 2, wherein the change of the component carrier capability is that the maximum number of the component carriers is decreased by one. ### Claim 4 (depends on 1) The method of claim 1, wherein determining whether to configure a measurement gap to at least one of the component carriers according to the component carrier capability indicating the maximum number of the component carriers and the first number of component carriers that have been configured to the mobile device comprises: configuring the measurement gap to at least one of the component carriers when the first number of component carriers that have been configured to the mobile device is equal to the maximum number of component carriers included in the component carrier capability. ### Claim 5 (depends on 1) The method of claim 1 further comprising: configuring the measurement gap to at least one of the component carriers when a message notifying that the mobile device receives data with the maximum number of component carriers is received from the mobile device. ### Claim 6 (depends on 1) The method of claim 1 further comprising: sending a measurement command to command the mobile device to perform an inter-frequency measurement or an inter-RAT measurement when no measurement gap has been configured to the mobile device. ### Claim 7 A network of a wireless communication system comprising a mobile device for handling measurement capability, the mobile device capable of communicating with the network through a maximum number of component carriers, comprising: means for receiving a capability information message indicating a component carrier capability, from the mobile device, wherein the component carrier capability indicates the maximum number of the component carriers; and means for determining whether to configure a measurement gap to at least one of the component carriers, according to the component carrier capability indicating the maximum number of the component carriers and a first number of component carriers that have been configured to the mobile device. ### Claim 8 (depends on 7) The network of claim 7 further comprising: means for determining that a change of the component carrier capability occurs, when reception of a multimedia broadcast multicast service (MBMS) message is activated on one of the component carriers and the component carrier for the reception of the MBMS message is a component carrier only dedicated to the reception of the MBMS message. ### Claim 9 (depends on 7) The network of claim 7 further comprising: means for configuring the measurement gap to at least one of the component carriers when a message notifying that the mobile device receives data with the maximum number of the component carriers is received from the mobile device. ### Claim 10 (depends on 7) The network of claim 7 further comprising: means for sending a measurement command to command the mobile device to perform an inter-frequency measurement or an inter-RAT measurement when no measurement gap has been configured to the mobile device.
