Abstract: A method includes: a second terminal apparatus receives first indication information from a first terminal apparatus, where the first indication information indicates that the first terminal apparatus requests to send data to a network device. The second terminal apparatus may further send second indication information to the network device, where the second indication information may indicate that the first terminal apparatus sends the data to the network device. Therefore, the network device may learn, based on the second indication information from the second terminal apparatus, that the first terminal apparatus is to send uplink data, to avoid blind detection performed by the network device due to uncertainty about whether there is uplink transmission of the first terminal apparatus, so that receiving performance of the network device can be improved, and processing complexity of the network device can be reduced.

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.
