A method and apparatus for reducing power consumption associated with establishing a connection in a near field communication system is disclosed. According to some embodiments, when requesting an active mode NFC connection, the initiator device can selectively extend transmission of its NFC carrier signal by an extended period of time after transmitting a polling command to the target device. The extended period of time allows the target device additional time to stabilize its clock signal and transmit its own NFC carrier signal back to the initiator device. As a result, the initiator device may wait to enable its NFC clock generator until after receiving a polling command that requests the active mode NFC session. In this manner, when the initiator device requests a passive mode NFC connection, the target device may not enable its NFC clock generator, thereby reducing power consumption. |
