Abstract: A method to reduce a probability of occurrence of a hidden node in a data transmission process in a high-frequency system is disclosed. The method implemented by a communications apparatus includes determining at least one beam to be used for sending a resource reservation message, where the at least one beam includes a first beam, where a direction of the first beam is opposite to a direction of a second beam, and where the direction of the second beam is a potential transmission direction in which the communications apparatus sends information. The method further includes sending the resource reservation message by using the at least one beam, where the resource reservation message includes a resource reservation request message or a resource reservation response message, where the resource reservation request message is used to request to reserve a transmission resource, and where the resource reservation response message is used to determine to reserve a transmission resource.

Abstract: A data transmission method and a device relate to the field of communication technologies and to a problem of resource waste when demodulation reference signal (DMRS) symbols account for a large proportion in orthogonal frequency division multiplexing (OFDM) symbols included in a subframe. The method includes receiving, by a network device, uplink data from N terminal devices in a time division multiplexing (TDM) manner, where the uplink data includes a DMRS of each of the N terminal devices, the N terminal devices share a target OFDM symbol, the target OFDM symbol transmits the DMRS of each of the N terminal devices, and N≥2, and performing, by the network device, channel estimation on an uplink channel of each of the N terminal devices based on the DMRS of each of the N terminal devices to obtain corresponding uplink data of each of the N terminal devices through parsing.

Abstract: A method for indicating a frame structure in a wireless local area network (WLAN) is provided. A sending device generates a transmission frame. The transmission frame includes a physical header. The physical header includes a frame structure indication. A subcarrier polarity of the frame structure indication is used to indicate a frame structure of the transmission frame. The sending device sends the transmission frame to a receiving device. In the transmission frame, a first subcarrier polarity indicates the transmission frame has a first frame structure, in which the physical header includes a field and a time domain repetition of the field; and a second subcarrier polarity indicates the transmission frame has a second frame structure, in which the physical header includes the field but does not include the time domain repetition of the field. The frame structure indication is an orthogonal frequency division multiplexing (OFDM) symbol.

Abstract: A first electronic device indicates at least two second electronic devices to enable respective sound recording functions, and indicates a third electronic device to send an ultrasonic signal. After enabling the sound recording functions, the at least two second electronic devices determine a relative location relationship between each of the at least two second electronic devices and the third electronic device based on respectively detected ultrasonic signals, and then send the relative location relationship between each of the at least two second electronic devices and the third electronic device to the first electronic device. Finally, the first electronic device sends the relative location relationship between each of the at least two second electronic devices and the third electronic device to the at least two second electronic devices and the third electronic device.
