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.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a first access network device determines configuration information, and sends the configuration information to a terminal. The first access network device is connected to a first core network device, and the first core network device uses a first or second communication standard. The configuration information includes status indication information of a first protocol layer (for example, a service data adaptation protocol (SDAP) layer) of the second communication standard, and the status indication information indicates the terminal to perform or not to perform a function of the first protocol layer. The first access network device determines a state of the first protocol layer based on a protocol layer specified in a communication standard of the core network device.

Abstract: Methods and systems for sharing a spectrum are described. In some examples, signal energy is determined in a channel of the spectrum by the access node. The channel is one of at least two channels including a first channel and a second channel. The first channel is associated with a first energy detection threshold (EDT), the second channel is associated with a second EDT that is different from the first EDT. A signal belonging to a traffic type is transmitted over the channel of the spectrum in response to the determined signal energy satisfying a criteria in related to the first EDT or the second EDT.

Abstract: The technology of this application relates to a method for determining a feature of a terminal and a communication apparatus. A mandatory feature set in a feature set of a terminal determined by the terminal or a network device is related to a type of the terminal. In this way, a mandatory feature set may be separately defined for different types of terminals. This customizes features of the terminals, helps minimize the features of the terminals, meets feature requirements of the different types of terminals, reduces chip costs and terminal implementation processing complexity, and implements terminal energy saving.
