Abstract: This application provides a terminal device and a communication method. The terminal device is in a dual-connectivity network including a long term evolution (LTE) link and a new radio (NR) link, and when the terminal device detects that the terminal device is in a power saving mode, and/or when the terminal device detects that battery power of the terminal device is less than or equal to a first preset value, and/or when the terminal device detects that temperature of a rear cover of the terminal device is greater than or equal to a second preset value, the terminal device releases the NR link, and uses the LTE link for communication.

Abstract: This application discloses when a first terminal device has performed a connection to a wireless access device based on a first channel (for example, a DFS channel), it may be determined whether both the first terminal device and a second terminal device support performing peer-to-peer communication in the first channel. When it is determined that both the configurations support establishing peer-to-peer communication in the first channel, peer-to-peer communication may be established based on the first channel. It can be ensured that a channel for communication between a device of at least one end and a wireless access device is the same as a channel for peer-to-peer communication, to effectively reduce occurrence of a scenario in which the terminal device performs time division switching between different channels, increase time for transmitting data in a peer-to-peer channel, and avoid a phenomenon like picture freezing, thereby improving user experience.

Abstract: This application provides a terminal device and a wireless communications method. When the terminal device is in a dual connectivity network including an LTE link and an NR link, the terminal device determines, based on a service transmission rate related to an actual transmission rate, whether to disconnect the NR link. If the service transmission rate is relatively low, the terminal device disconnects the NR link. If the service transmission rate is relatively high, the terminal device does not disconnect a first link, and uses both the NR link and the LTE link for communication. In this way, power consumption of the terminal device can be effectively reduced without affecting the user experience on transmission rate, the user experience on power consumption is improved, and the user experiences on transmission rate and power consumption are balanced to some extent.

Abstract: This application provides a method for reducing power consumption and an electronic device. In the method, when a Wi-Fi packet of a non-key type is received by the electronic device, if it is determined, based on a reception status of the packet of this type, that there is an abnormal Wi-Fi packet wakeup event currently, a Wi-Fi module is turned off when the electronic device satisfies a user perception-free condition.

Abstract: Embodiments of this application are applied to the communication field, and provide a communication method and an electronic device. In a scenario in which operating frequency bands of Wi-Fi communication and Bluetooth communication overlap, an electronic device may obtain a first communication indicator threshold after determining that the electronic device meets a first preset condition, and then compare a latest communication indicator obtained in real time with the first communication indicator threshold, to determine whether the latest communication indicator meets a second preset condition. When the latest communication indicator meets the second preset condition, the electronic device may perform Wi-Fi communication through a first antenna and perform Bluetooth communication through a second antenna. In this way, interference between the Wi-Fi communication and the Bluetooth communication can be reduced, and good transmission performance can be maintained.

Abstract: A method for adjusting a quantity of data streams, a terminal, and a MIMO system. In the method, the terminal may actively negotiate the quantity of transport layers used in a downlink data transmission process with a network device based on an operation status of the terminal, so as to adaptively and dynamically adjust the quantity of data streams in the downlink data transmission process. This may reduce power consumption of the terminal and prolong a standby time of the terminal without affecting user experience while meeting requirements for a data transmission rate of the terminal.

Abstract: A method and apparatus for transmitting information through a topological quantum error correction system based on multi-space-time transformation including steps of initializing quantum information, detecting an error in quantum information transmission, correcting the error in quantum information transmission, and decoding the information in quantum information transmission. Information safety is improved and only a quantity of devices for generating quantum states needs to be increased. A stabilizer is used to analyze code symmetry, for error detection, measurement, and correction. Any information about an encoded qubit is not revealed during odd/even parity measurement, so that an encoding state of the encoded qubit remains unchanged. A double-layer convolutional neural network model in an adversarial network can find an error correction chain with a best effect.
