Abstract: This application provides a method for determining orientation information and an electronic device. In the method, a first electronic device may determine, based on a received second sequence, whether a device sending a first sequence associated with the second sequence is a second electronic device. If the device sending the first sequence is the second electronic device, the first electronic device may determine orientation information of the second electronic device based on the first sequence. This helps determine an orientation of the second electronic device or an orientation of the first electronic device based on the orientation information, and prevent a user from manually participating in orientation configuration, thereby reducing operation complexity and improving user experience.

Abstract: A ranging method and apparatus are provided. The method includes: obtaining first measurement information and second measurement information (S410), where the first measurement information includes a plurality of groups of sampled data that are obtained by a first device by sampling retroreflection measurement signals received through a plurality of antenna channels of a single antenna, and the second measurement information includes a plurality of groups of sampled data that are obtained by a second device by sampling measurement signals received through a plurality of antenna channels of each of a plurality of antennas; and determining a distance between the first device and the second device based on the first measurement information and the second measurement information (S420). In this method, ranging is performed based on multi-antenna switching frequency hopping, so that a ranging delay meets a requirement, and ranging precision and robustness are improved.

Abstract: The method is applied to a communications system including a first network device, a second network device, and a terminal device. The terminal device is communicatively connected to the first network device and the second network device respectively. The method includes: sending, by a network device, a first message to the terminal device, where the first message is used to determine that the terminal device stops communication with the first network device, or the first message is used to determine that the terminal device releases a protocol stack and a data radio bearer that are corresponding to the first network device; and the network device is the first network device or the second network device. Therefore, power consumption of the terminal device or the first network device and waste of air interface resources can be reduced, and flexibility can effectively be improved in a communication process.
