Abstract: Aspects relate to transmission control. In some examples, a first apparatus (e.g., a wireless communication device) may output a first packet for transmission to a second apparatus. Subsequently, the first apparatus may suspend a second packet from being output for transmission to the second apparatus. In some examples, the suspension of the second packet may be based on a first voltage level of a power source being less than or equal to a first threshold (e.g., due to the transmission of the first packet).

Abstract: A method, apparatus, and computer-readable medium are provided that improve power management for devices communicating via Bluetooth (BT) over Internet Protocol (BTOIP). The apparatus for wireless communication for a first device receives a first set of packets from a second device during a time period associated with a training phase for the first device. The apparatus determines an arrival time of a first packet of the first set of packets. The apparatus determines, based on the arrival time and a wakeup time interval, a wakeup time for the first device. The apparatus causes, based on the wakeup time for the first device and one or more attributes associated with the first set of packets, a shutdown of the first device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, via a wireless link, with an audio device using a first configuration having first values for communication parameters. The WCD may transmit an indication to switch to a second configuration based at least in part on a configuration switch trigger, the configuration switch trigger being based at least in part on one or more of a link quality metric associated with the wireless link or a change of a use state of the WCD, and the second configuration having second values for the communication parameters associated with a reduction in voltage-induced interference in an audio output of the audio device. Numerous other aspects are described.

Abstract: Techniques and apparatus for determining intrinsic resistance and/or battery life of a coin cell battery based on the recovery time of the battery voltage after a significant current draw event. Once the intrinsic resistance and/or battery life is known, a device powered by the coin cell battery can take action to lengthen the battery's useful lifetime. One example technique of operating a device powered by a battery generally includes performing an operation with a relatively high current draw from the battery compared to other operations of the device, determining a recovery time of a voltage of the battery after the operation, and estimating a position of the battery in a lifetime of the battery based on the recovery time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, during a time period, with a peripheral device via a wireless connection, the wireless connection using a first channel for communication. The WCD may monitor a second channel during a concurrency time of the wireless connection, the second channel using a channel availability check (CAC) to obtain resources for communicating, and transmitting an indication to switch to the second channel for communication. In some aspects, the WCD may communicate with low-latency requirements. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that enable a keep-alive mode for wakeup radio (WUR) operation. A device may determine whether or not at least one keep-alive frame was received at a WUR during an expected on duration of a duty cycle period associated with the WUR. Another device may generate at least one keep-alive frame. The device may output the at least one keep-alive frame for transmission to a WUR of a second wireless node during an expected on duration of a duty cycle period associated with the WUR of the second wireless node.
