Abstract: Various aspects are described herein in connection with methods and/or apparatuses of near-field communication. For example, various methods and apparatuses include an NFC transmitter configured to send a communication establishment (CES) command. The CES command includes at least one transmitter communication enhancement (TX CEN) parameter comprising an operation setting based on a geographic location of the NFC transmitter. The NFC transmitter is configured to determine whether a CES response was received from an NFC receiver and adjust a communications channel based on at least one receiver (RX) CEN parameter included in the CES response based on the at least one TX CEN parameter. Various methods and apparatuses also include a NFC receiver configured to receive a CES command from an NFC transmitter and send a CES response. The CES response includes at least one RX CEN parameter comprising an operation setting based on a geographic location of the NFC receiver.

Abstract: Various aspects for motion detection and/or gesture recognition in a wireless communication device are disclosed, and may include determining whether a source address of a received data packet is a source address of the wireless device, determining whether a process for the motion detection and/or gesture recognition is enabled in the wireless device and processing one or more received signals for the motion detection and gesture recognition occurring in a proximity of the wireless device. The one or more received signals are transmitted from a transmit antenna of the wireless device and received via a receive antenna of the wireless device. The received data packet is carried by at least one of the one or more received signals. The received data packet may be a Bluetooth data packet carrying the source address.

Abstract: Disclosed are methods and apparatuses for reducing fractional spurs in an All-Digital Phase Lock Loop (ADPLL). An exemplary apparatus includes a crystal oscillator configured to generate a first frequency reference signal, a non-integer divider coupled to the crystal oscillator and configured to divide the first frequency reference signal by a non-integer variable to generate a second frequency reference signal, and a multiplexor coupled to the non-integer divider and the crystal oscillator and configured to output the first frequency reference signal or the second frequency reference signal to the ADPLL, wherein the multiplexor is configured to output the second frequency reference signal based on the ADPLL being tuned to a low fractionality channel.

Abstract: Aspects disclosed herein relate to mitigating an antenna over-coupling condition in near field communication (NFC) devices. A transmission signal for a transmitted carrier is generated at a transmit circuit of an initiator NFC device, and a received carrier is received at a receive circuit of the initiator NFC device. The initiator NFC device can detect an antenna over-coupling condition related to antenna coupling with a remote NFC device based at least in part on the transmission signal and the received carrier. Where the condition is detected, at least one of a transmit circuit parameter for the transmit circuit or a receive circuit parameter of the receive circuit is modified to reduce the antenna over-coupling condition
