    Abstract: A method is described. The method includes counting a number of successive information frame (I-frame) retransmissions due to a guard timer expiring. A contactless front-end (CLF) transmits the I-frame to a secure element (SE) over a single wire protocol (SWP) interface. The method also includes discontinuing I-frame retransmission when the count equals a retransmission threshold. The method further includes deactivating the SWP interface.

    Abstract translation: 描述了一种方法。 该方法包括由于保护定时器到期而对多个连续的信息帧（I帧）重传进行计数。 非接触式前端（CLF）通过单线协议（SWP）接口将I帧传输到安全元件（SE）。 该方法还包括在计数等于重传阈值时停止I帧重发。 该方法还包括禁用SWP接口。

    Abstract: An apparatus for wirelessly transmitting charging power is provided. The apparatus comprises a transmit coil configured to generate a wireless charging field for wirelessly transmitting charging power when driven by a current. The apparatus comprises a control circuit configured to cause the transmit coil to transmit a packet via the wireless charging field, wherein the packet comprises information indicative of the presence of the wireless charging field to cause a chargeable device to electrically disconnect a communication circuit from a receive coil within the chargeable device. The control circuit is further configured to cause the transmit coil to transmit the packet periodically based on a predetermined interval. The predetermined interval has a shorter duration than a duration of a communication interval of the communication circuit. The control circuit is further configured to reduce a magnitude of a strength of the wireless charging field during packet transmission.

    Abstract: A method of communicating with a secure element (SE) is described. The method includes transmitting successive RSET frames from a single wire protocol (SWP) interface to an SE, the successive RSET frames including RSET frame retransmissions. The method also includes counting a number of successive RSET frame retransmissions due to a timer expiring. The method further includes generating a firmware interrupt in response to determining that the count has reached a threshold. The method additionally includes deactivating the SWP interface based on the firmware interrupt.

    Abstract: A method for wireless communication by a wireless communication device is described. The method includes receiving geographic location information. The method also includes querying a geographic location tuning database for tuning parameter values corresponding with the geographic location information. The method further includes determining one or more tuning parameters to change based on the tuning parameter values. The method additionally includes adjusting an antenna for inductively coupled communication with a reader device according to the determined tuning parameters.
