Abstract: A user equipment wireless communication device in a wireless communication environment receives a signal from the network that includes a radio network temporary ID. From the radio network temporary ID, the user equipment is capable of determining whether a phase tracking reference signal is present based on the radio network temporary ID. If any of these are identified by the radio network temporary ID, then the user equipment determines that a phase tracking reference signal is present. After the user equipment has determined that the phase tracking reference signal is present, the user equipment can then determine which phase tracking reference signal antenna ports are to be used based on the values of the transmitted precoding matrix indicator value and the transmit rank indicator.

Abstract: A first electronic device is wireless connected to an audio output device that is also concurrently wirelessly connected with a second electronic device that is different from the first electronic device and playing first audio corresponding to first audio data transmitted by the second electronic device to the audio output device. The first electronic device, in response to detecting a user request to play a second audio that is associated with a media item, transmits to the audio output device second audio data corresponding to the second audio. In accordance with the second audio data being transmitted to the audio output device, the audio output device ceases playing the first audio and begins playing the second audio.

Abstract: A receiver circuit that limits the frequency of a clock signal used in a computer system is disclosed. An embodiment of the receiver circuit includes a front-end circuit configured to generate an equalized signal, a clock generator circuit configured to generate a clock signal using a plurality of samples of the equalized signal, and a measurement circuit. The measurement circuit is configured to monitor a frequency of the clock signal and activate an indication signal in response to determining that the frequency of the clock signal exceeds a threshold frequency. In response to activation of the indication signal, the clock generator circuit is configured to set the frequency of the clock signal to a particular frequency.

Abstract: A method for providing navigation assistance using a head-worn device that has a camera, several microphones, and several speakers. The method captures sound in an environment as a plurality of microphone audio signals, captures, using the camera, a scene of the environment as a digital image, and processes the digital image to detect an object therein. The method selects, in response to the detection of the object, one of several navigation audio rendering modes. The several navigation audio rendering modes include a first mode that activates an acoustic transparency function to cause the speakers to reproduce the sound of the environment, a second mode that sonifies the object and activates the acoustic transparency function, and a third mode that sonifies the object, partially activates the acoustic transparency function, and an activates active noise cancellation function.

Abstract: A user equipment including a transceiver and a processor is configured to receive, from a base station and via the transceiver, a set of resource indicators identifying a set of beams and a configuration for reporting a duty cycle for transmission in an uplink direction for at least one resource indicator of the set of resource indicators. The processor is also configured to, at least one of periodically or based on an event reported by a body proximity sensor (BPS), determine the duty cycle for transmission in the uplink direction for the at least one resource indicator of the set of resource indicators; and transmit, to the base station via using the transceiver, the determined duty cycle and the corresponding at least one resource indicator of the set of resource indicators according to the received configuration for reporting the duty cycle.

Abstract: Some aspects of this disclosure include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and/or sub-combinations thereof, for implementing multi-credential mapping mechanisms in wireless communication networks, such as a wireless local area network (WLAN). The multi-credential mapping mechanisms can use pointer schemes for communicating multiple credentials (e.g., Authentication and Key Managements (AKMs) and ciphers) in the wireless communication networks. The multi-credential mapping mechanisms can reduce congestion in the communication medium and improve the communications between an access point (AP) and stations (STAs).
