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.

This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

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.

Certain aspects of the present disclosure relate to methods and apparatus for dynamic UE-Category switching for enhanced idle mode power savings. A method for wireless communications by a user equipment (UE) is provided. The method generally includes, determining that a cell supports a second UE category, lower than a first UE category; and while in an idle mode: operating in the cell according to the first UE category; and taking action to operate in the cell according to the second UE category based on the determination.

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.

Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence corresponding to an output of a convolutional modulation between a plurality of values and an intermediate sequence. The intermediate sequence is generated by inserting a set of coefficients between coefficients of the input sequence. Each non-zero coefficient of the set of coefficients is inserted between a first adjacent coefficient and a second adjacent coefficient. Each non-zero coefficient has a power that is between a first power of the first adjacent coefficient and a second power of the second adjacent coefficient and a phase value between a first phase value of the first adjacent coefficient and a second phase value of the second adjacent coefficient. The method also includes generating a waveform using the output sequence.

Embodiments of this disclosure provide a signal quality information obtaining method, a device, and a system. One example method includes: a source network device obtains configuration information of an SRS of a terminal device and sends the configuration information of the SRS to a target network device and the terminal device. A first cell of the target network device monitors the SRS based on the configuration information of the SRS, and then the target network device sends, to the source network device, signal quality information of the SRS detected by the first cell. Correspondingly, the source network device receives, from the target network device, the signal quality information of the SRS detected by the first cell, where the first cell is a cell controlled by the target network device, the first cell is an energy-saving cell, and the energy-saving cell is a cell that does not send an SSB.

A mobile device allows transmission of additional outgoing application data requests in response to occurrence of receipt of data transfer from a remote entity, user input in response to a prompt displayed to the user, and a change in a background status of an application executing on the mobile device. Additional outgoing application data requests are foreground application requests.
