Abstract: System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperature-calibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperature-calibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device. The trigger condition can include first use or power-on, charging, presence in an outdoor environment, variation in operating temperature, pre-specified time, and/or user input pertaining to the mobile device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a secondary peripheral device may obtain microphone data. The secondary peripheral device may select a peripheral-to-central (P2C) slot, among P2C slots of an enhanced synchronous connection oriented (eSCO) interval, that occurs after a first P2C slot in the eSCO interval. The secondary peripheral device may transmit the microphone data to a primary peripheral device in the P2C slot. Numerous other aspects are described.

Abstract: Various embodiments include systems and methods for balancing battery cycles of paired earbuds. A processor in an earbud charging case may receive battery level information from a first earbud operating in a deep sleep mode, determine a battery differential index (BDI) value, and send an instruction message to the first earbud indicating the first earbud should switch roles with a second earbud. An earbud may start a timer upon beginning to operate in a dormant mode, transition from operating in the dormant mode to operating in a non-dormant mode in response to expiration of the timer, send a message to a paired earbud indicating that the earbud has transitioned, and receive a message from the paired earbud indicating that the earbud should switch from operating in the dormant mode to operating in the deep sleep mode and periodically broadcasting an advertisement.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first device. The first device may decrypt a first packet using a first nonce associated with a first expected packet number. The first device may determine a next nonce based on the decryption of the first packet, wherein the next nonce is different when the first packet is unsuccessfully decrypted than when the first packet is successfully decrypted. The first device may decrypt a second packet received consecutive to the first packet based on the next nonce.

Abstract: There is a need to enable a wireless device to output signals such that the natural instincts of the user may be triggered. The present disclosure provides a solution by enabling a wireless device to determine a time delay and intensity difference associated with an audio output at a subset output devices based at least in part on a perceived spatial placement of at least one signal, a position of the transmitting device, and/or a signal strength associated with the signal. Using the time delay and the intensity difference, the output devices farthest from the transmitting device may output the at least one signal using the time delay and the intensity difference such that the user may detecting differences in the sound wave's time of arrival and intensity at the left ear versus the right ear, and thus, perceive the location of the audio source.

Abstract: Methods, apparatuses, systems and computer-readable media for addressing the aging of oscillation (XO) crystals are presented. Some embodiments may determine a change of age of the XO crystal since last prior use of the XO crystal. Embodiments may then determine that at least one calibration parameter is not suitable for use in at least one calibration technique of the XO crystal, based on the change of age of the XO crystal. Embodiments may then determine at least one fresh calibration parameter configured to update the at least one calibration parameter for suitable use in the at least one calibration technique of the XO crystal.

Abstract: Systems and methods for reducing boot time in a computer system divide the boot instructions into a start-up boot instruction segment and a mission-mode boot instruction segment. The start-up boot instruction segment is downloaded from persistent memory of the computer system to a random access memory (RAM) of the computer system and executed prior to a radio frequency (RF) analog (RFA) module of the computer system perform an RF calibration process that calibrates the RFA module to perform a wireless communication protocol. During the RF calibration process, the mission-mode boot instruction segment is downloaded from persistent memory to RAM and executed. Downloading the mission-mode boot instruction segment during the RF calibration process greatly reduces the overall amount of time required to boot the computer system.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first peripheral device may establish, with a user equipment (UE), a first connected isochronous stream (CIS), a second CIS, and a control channel for the first CIS and the second CIS, where the first peripheral device is configured to output audio signals for the first CIS and handle feedback for the first CIS. The first peripheral device may transmit, to a second peripheral device paired with the first peripheral device, an indication that the second peripheral device is to output audio signals for the second CIS and handle feedback for the second CIS. The first peripheral device may receive the first CIS, while maintaining the control channel for the first CIS and the second CIS. Numerous other aspects are described.
