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: 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: Methods performed by a first sink device, a source device, or a second sink device. The first sink device is connected to a source device via a first communication link and a second sink device via a second communication link, wherein the second sink device is configured to eavesdrop on communications between the first sink device and the source device on the first communication link. The methods include determining an occurrence of a trigger event and modifying an operation of at least one of the first sink device, the second sink device or the source device based at least on the trigger event occurring.

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: Some embodiments include a system, method, and computer program product for managing the Ultra Wideband (UWB) systems, especially when the UWB system is collocated with another wireless system (e.g., WiFi) to transmit and/or receive UWB signals with an occupied bandwidth (OBW) that satisfies a UWB OBW standard (e.g., a UWB OBW>=500 MHz.) In some embodiments a TailBit signal (e.g., a periodic signal at a selected frequency) is added to a UWB packet to generate frequency components at the selected frequency that enables the power spectrum of the TailBit UWB signal to satisfy the UWB OBW standard. In some embodiments an altered code sequence is used to generate an altered spread signal, where the altered code sequence reduces or removes a frequency component peak near DC frequency of the power spectrum of an altered UWB signal, resulting in altered UWB OBW that satisfies the UWB OBW standard.

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 device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Abstract: This application relates to systems, methods, and apparatus for testing operability of a mobile device with a reader device. In some embodiments, a testing system is set forth for automatically placing the mobile device proximate to the reader device in order to initiate a wireless transaction between the mobile device and the reader device. Depending on whether the mobile device is determined to be operable with the reader device, the testing system can automatically place the mobile device proximate to another reader device for testing. In this way, reductions in testing time can be manifested as a result of automating the testing process.
