Title:
データ伝送方法、ネットワークデバイス及び端末デバイス
Document Type and Number:
Japanese Patent JP7303851
Kind Code:
B2
Abstract:
Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method includes: detecting, by a network device, a first signal in an uplink signal; determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal; and 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. This avoids complexity and a reliability risk that are caused by completely blind detection performed by the network device, and can effectively reduce a delay and signaling overheads.
