Abstract: This application provides example positioning methods and example apparatuses. One example method includes sending, by a positioning management network element, a positioning measurement request to a positioning measurement network element. The positioning measurement request is used to request the positioning measurement network element to feed back channel state information of a terminal device. Then, the positioning management network element receives a positioning measurement response from the positioning measurement network element. The positioning measurement response includes the channel state information of the terminal device. Then, the positioning management network element determines a location of the terminal device based on the channel state information of the terminal device.

Abstract: Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.

Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method may include detecting, by a network device, a first signal in an uplink signal. The method may also include determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal. Furthermore, the method may include receiving, by the network device, the uplink signal based on the signal structure, and/or responding to the uplink signal based on the signal structure. According to the data transmission method in the embodiments of this application, before receiving data, the network device can determine the signal structure, used by the terminal device, of the uplink signal, and then use a corresponding receiving method to avoid complexity and a reliability risk that are caused by completely blind detection performed by the network device, as well as to effectively reduce a delay and signaling overheads.
