Abstract: An electronic apparatus, a control circuit, and a transmission control method includes a control circuit and at least two communication circuits, where the control circuit is configured to obtain first service data, and selectively distribute the first service data to at least one of the communication circuits, and any one of the communication circuits can support one wireless communication protocol.

Abstract: In a resource allocation method, a master control device establishes a first asynchronous connection link with a first slave device. The master control device establishes a first synchronous connection link with the first slave device based on the first asynchronous connection link. The master control device dynamically allocates a first air interface resource to the first asynchronous connection link based on indication information in a data packet transmitted on the first synchronous connection link. The indication information indicates whether control signaling transmission needs to be performed on the first asynchronous connection link.

Abstract: This application provides a wireless headset, an audio device, and a system. The wireless headset includes: a first headset, including: a first microphone, configured to obtain, through voice capturing, first audio data corresponding to a first channel; a first encoder, configured to encode the first audio data to obtain a first audio packet; and a first wireless transceiver, configured to transmit the first audio packet to an audio device over a first communication connection; and a second headset, including: a second microphone, configured to obtain, through voice capturing, second audio data corresponding to a second channel; a second encoder, configured to encode the second audio data to obtain a second audio packet; and a second wireless transceiver, configured to transmit the second audio packet to the audio device over a second communication connection. This implementation can improve performance of the wireless headset.

Abstract: This application discloses a communication method applied to a binaural wireless headset, and an apparatus, and relates to the field of chip technologies. The binaural wireless headset includes a first earpiece and a second earpiece. The first earpiece and the second earpiece separately perform wireless communication with a terminal. The method may include: The first earpiece establishes a communication connection with the second headset. The first earpiece receives first indication information, and determines, based on the first indication information, that there is a reception failure when the second earpiece receives a first data packet from the terminal. When the first earpiece successfully receives the first data packet from the terminal, the first earpiece forwards the first data packet to the second earpiece by using the communication connection. Embodiments of this application are used for data packet forwarding/retransmission between binaural wireless headsets.

Abstract: An indoor positioning method includes: receiving a first measurement parameter obtained by a first device by measuring a second device in a first coordinate system, where the first measurement parameter includes a first angle and a first distance, the first angle is an angle of the second device in the first coordinate system, and the first distance is a distance of the second device relative to an origin of coordinates of the first coordinate system; determining a first spatial position of the second device in the first coordinate system based on the first angle and the first distance; and determining a spatial position of the second device in a geodetic coordinate system based on the first spatial position and a conversion relationship between the first coordinate system and the geodetic coordinate system.

Abstract: An electronic device includes a first graphics processing subsystem, a second graphics processing subsystem, and a screen. The first graphics processing subsystem includes a first application processor, a first graphics processing unit, and a first memory. The second graphics processing subsystem includes a second application processor, a second graphics processing unit, and a second memory. The first graphics processing unit renders a first GUI. The screen displays the first GUI. The second graphics processing unit renders a second GUI, and the second GUI and the first GUI belong to different interface types. The screen displays the second GUI. A display processing method applied to the electronic device is also provided, wherein the first graphics processing subsystem can be switched to the second graphics processing subsystem based on complexity of a to-be-displayed GUI.

Abstract: This application provides a data sending method and apparatus applicable to Bluetooth communication. A data sending method applicable to Bluetooth communication in this application includes: sending at least one first packet to a first receiving device by using a Bluetooth communication connection, where the at least one first packet is generated by using a first packet assembly manner; determining, based on a receiving status of at least one piece of feedback information sent by the first receiving device, to generate at least one second packet by using the first packet assembly manner or a second packet assembly manner, where the at least one piece of feedback information is an acknowledgment or a negative acknowledgment fed back by the first receiving device after receiving the at least one first packet; and sending the at least one second packet to the first receiving device by using the Bluetooth communication connection.
