Abstract: A device implementing a system for NFC communication with a second device includes an antenna and a processor configured to transmit a pulse signal for detection of another device within proximity of the device, and to detect, in conjunction with transmission of the pulse signal, that a first value of a measurement parameter of the antenna satisfies an initial detection factor. The processor is further configured, in response to the detection, to set a confirmation detection factor for the measurement parameter of the antenna based at least in part on the first value of the measurement parameter of the antenna, to transmit a confirmation pulse signal, and to initiate a second polling for reception of data from the other device when a second value of the measurement parameter of the antenna detected in conjunction with transmission of the confirmation pulse signal satisfies the confirmation detection factor.

Abstract: Manners of complying with SAR limits at a user equipment (UE) configured to establish a first communication connection using a first radio and a second communication connection using a second radio. The UE determines that a first application associated with the first communication connection is to be prioritized over a second application associated with the second communication connection, determines a specific absorption rate (SAR) value associated with the UE and modifies, responsive to the SAR value associated with the UE, a parameter associated with the first radio or the second radio based on at least the priority of the first application relative to the second application.

Abstract: Exemplary embodiments include a system having a first wireless audio output device and a second wireless audio output device. One of the first or second audio output devices is configured to one of connect as a slave to a source device in a first piconet and connect as a master to the other one of the first or second audio output devices in a second piconet. The one of the first or second wireless audio output devices determines whether an audio packet transmitted by the source device via the first piconet was received by the first wireless audio output device and the second wireless audio output device, and, when at least one of the first wireless audio output device or the second wireless audio output device did not receive the audio packet, the audio packet is exchanged between the first and second wireless audio output devices via the second piconet.

Abstract: A transceiver that implements a high dynamic range NFC reader mode receiver may include a transmitter circuit to generate a transmit (TX) signal for communication to a first device via an antenna. The transceiver may further include a receiver circuit that is in communication with the first device via the antenna. The receiver circuit includes a mixer circuit and an adder circuit. The mixer circuit mixes a carrier signal with a first signal to generate a baseband signal. The adder circuit is coupled to the antenna and produces the first signal by adding a receive (RX) signal with a second signal to reduce a component of the TX signal included in the RX signal. The second signal is produced by processing a TX clock signal generated by the transmitter circuit.

Abstract: A device implementing a system for NFC communication includes a processor configured to receive, from an other device, pulse signals for detecting proximity of the device with the other device. The processor is further configured to determine an interval at which the pulse signals are received from the other device. The processor is further configured to determine a time when the other device is expected to transmit a subsequent pulse signal based at least in part on the determined interval. The processor is further configured to transmit a signal to the other device based on the determined time when the other device is expected to transmit the subsequent pulse signal.

Abstract: Exemplary embodiments include a system having a first wireless audio output device configured to connect to a source device via a first piconet and a second wireless audio output device configured to connect to the first wireless audio output device via a second piconet. A schedule of the first piconet includes a plurality of slots associated with an audio packet, a first subset of the slots used by the source device to transmit the audio packet, the first and second wireless audio output devices tuning to the first piconet to listen for the transmissions of the audio packet, and when, after a last one of the first subset of slots, the first or second wireless audio output devices did not receive the audio packet, the first and second wireless audio output devices exchange information via the second piconet such that the both wireless audio output device receive the audio packet.

Abstract: A wireless communication device includes a number of radio-frequency (RF) antennas and one or more radio circuits. Each radio circuit includes a receive (RX) chain to process RX signals and a transmit (TX) chain to process TX signals. An RF switch network couples at least one RF antenna to at least one radio circuit. A baseband processor controls a configuration of the RF switch network. The baseband processor determines a plurality of parameters and controls the RF switch network based on at least one of the parameters. The parameters are determined during a training interval including at least an inter-frame space (IFS). The configuration of the RF switch network is based on the determined parameters and is employed for selection of an antenna to improve a link performance when used for communication of a next packet following the IFS.
