A power consumption control method, a chip system, and a terminal device in the field of terminal technologies is provided. The method includes: detecting, by a terminal device, a screen state and data traffic of the terminal device; and switching the terminal device from a normal working mode to a low power mode when the screen state is a screen-off state and the data traffic is less than or equal to a preset traffic threshold. In the low power mode, the terminal device does not receive downlink data, and current in a radio frequency path of the terminal device drops to a preset current, where the preset current is less than a current value of the radio frequency path in the normal working mode.

An access control system includes an energy efficient access control that operates as a Wi-Fi access point that broadcasts a Service Set Identifier (SSID) as indicator of access control level to communicate with a mobile device with WPA2 PSK.

An electronic device includes a first screen and a second screen. A high-power sensor of the electronic device is in a disabled state, and a low-power sensor of the electronic device is in an enabled state. The electronic device includes a foldable device. Based on this, after the electronic device receives a screen-on trigger signal from the low-power sensor or a processor of the electronic device, the electronic device determines a to-be-lit-up first target screen based on the screen-on trigger signal, and then controls the first target screen to be lit up.

The present disclosure provides device power saving methods and apparatuses. A method is applied to a first device which simultaneously communicates data frames with a second device via multiple links and includes: generating a first message frame including an identifier information bit used to indicate that the first device is a candidate to enter a sleep mode in one or more links of the multiple links; by sending the first message frame to the second device and receiving a second message frame fed back by the second device, whether to enter a sleep mode in a sleep-mode-candidate link indicated by the identifier information bit is determined based on the second message frame used to confirm or reject the first device to enter a sleep mode in the sleep-mode-candidate link indicated by the identifier information bit. The method may determine whether a device enters a sleep mode under multi-link communication.

According to one example embodiment, a wireless communication device having an associated first serial code. The wireless communication device includes a receiver, a processor, and a transmitter. The wireless communication device starts up intermittently. The receiver receives a second serial code different from the first serial code from a second the wireless communication device different from the wireless communication device. The processor stores the second serial code received by the receiver in a memory, and acquires the first serial code and the second serial code from the memory. The transmitter transmits the first serial code and the second serial code.

Various embodiments set forth a device comprising a battery that generates a first power, and an inductive sensor that generates a magnetic field based on the first power, and generates, based on a change to the magnetic field, a sensing signal indicating a presence of an object, where delivery of the first power to the inductive sensor is based on one or more additional signals.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may determine a set of inputs to a neural network configured to predict radio frequency channel conditions or a user context associated with the UE. In some aspects, the set of inputs includes historical data related to a wireless environment, a communication pattern, or a behavior pattern associated with the UE. The apparatus of the UE may determine, using the neural network and based at least in part on the set of inputs, an optimal number of aggregated carriers to maximize one or more of a power parameter or a performance parameter. The apparatus of the UE may communicate using the optimal number of aggregated carriers. Numerous other aspects are described.

Provided is device linked context identification and notification. Context data of a user profile of a user is retrieved from an external storage. The context data is analyzed to place user activities of the user and surrounding activities around the user in activity categories and to assign tags for the user activities and the surrounding activities. In response to receiving a notification that shutdown of a first device being used by the user is about to occur, current context data and historical context data are compared to determine whether the current context data for the user is one of typical and unusual and to predict a future action of the user. A device shutdown notice is sent to a second device with the current context data, the determination of whether the current context data for the user is one of typical and unusual, and the prediction of the future action.

The handset and base station disclosed save battery life and processor cycles by further analyzing communication types and patterns to limit communications to times and situations where communications are more likely and where battery preservation will have a significant impact. In one embodiment, the server side controls the timing of communicating voice signals, data signals and control signals to save battery life in a portable computing device.

Disclosed are systems and techniques for extended reality optimizations using radio frequency (RF) sensing. An example method can include obtaining RF sensing data; determining, based on the RF sensing data, reflected paths of one or more reflected RF signals, each reflected RF signal including a reflection of a transmitted signal from one or more objects in physical space; comparing the one or more reflected paths, to a field-of-view (FOV) of an image sensor of the device; and based on the comparison, triggering an action by the device and/or the image sensor.
