1. An apparatus comprising:
- a Near Field Communication (NFC) transceiver configured to generate a trigger signal in response to presence of another NFC device within an NFC communication range of the NFC transceiver and to receive application data from the other NFC device; and
a controller configured to control the apparatus to transition to or from a wake state when the trigger signal is received from the NFC transceiver and to control the apparatus to execute an application according to the application information received from the other NFC device,wherein, when the application data is received from the other NFC device, the controller controls the NFC transceiver to transmit, to the other NFC device, a request for the other NFC device to stop executing a corresponding application.

10. A method for power state transition in an apparatus supporting Near Field Communication (NFC), the apparatus comprising:
-
determining that another NFC device has entered within an NFC communication range of the apparatus; generating a trigger signal in response when the other NFC device enters into communication range of the apparatus; controlling a power state transition to a wake state or to a sleep state according to the trigger signal; receiving application data from the other NFC device; after transitioning to the wake state, executing an application on the apparatus according to the application data; and after receiving the application data, transmitting a request, to the other NFC device, to terminate execution of a corresponding application. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An apparatus, comprising:
-
a Near Field Communication (NFC) transceiver configured to generate a trigger signal in response to presence of another NFC device within an NFC communication range of the NFC transceiver and to receive application data from the other NFC device; a Power Management Integrated Circuit (PMIC) configured to receive the trigger signal and to generate an interrupt signal for transitioning to or from a wake state; and a controller configured to transition the apparatus to or from the wake state according to the interrupt generated by the PMIC and to control the apparatus to execute an application according to the application information received from the other NFC device, wherein, when the application data is received from the other NFC device, the controller controls the NFC transceiver to transmit, to the other NFC device, a request for the other NFC device to stop executing a corresponding application.
