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 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.
