Abstract: This application discloses a data transmission method and apparatus, and relates to the field of short-range wireless communication technologies. In this application, a master device transmits data with slave devices based on an event cycle. Each event cycle includes a first sub-cycle and a second sub-cycle. In the first sub-cycle, the master device transmits data to each slave device, and receives indication information fed back by each slave device based on a data receiving status of the slave device. A retransmission slot is dynamically configured for each slave device in the second sub-cycle based on the indication information of the slave device in the first sub-cycle, so that retransmission slots corresponding to all slave devices in the second sub-cycle can be consecutive slots, and remaining slots in the second sub-cycle are also consecutive slots. This helps effectively use the remaining slots and reduce a waste of air interface resources.

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: Example communication methods and apparatus are described. In one example method, a first device generates an advertising message, and sends the advertising message to a second device. The advertising message includes first indication information, and the first indication information indicates a role expected by the first device. The role expected by the first device is a grant node or a terminal node.

Abstract: This application relates to time frequency synchronization-based positioning methods and apparatuses. In an example method, a first device completes time-frequency synchronization with a second device via a narrowband system, to obtain time-frequency synchronization information. The first device performs positioning between the first device and the second device via a wideband system when the first device determines, at a media access control (MAC) layer, that the time-frequency synchronization information reaches time-frequency precision associated with the wideband system. The first device exchanges a positioning result with the second device via the narrowband system.

Abstract: This application relates to a resource negotiation method and apparatus, a device, a computer-readable storage medium, and a computer program product. In an example method, a first primary device obtains, through a secondary device, resource allocation information provided by a second primary device. The resource allocation information indicates at least a time resource for transmission from the first primary device or the second primary device to the secondary device. The first primary device determines, in an event periodicity based on the obtained resource allocation information, a first time resource for transmission from the first primary device to the secondary device.

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.
