摘要： This application provides a transmission method and apparatus. The method includes: A first terminal device obtains information about N SL transmission units. The N SL transmission units are used on an SL for sending a data packet of a unicast connection or a groupcast communication group. The first terminal device transmits the data packet to a second terminal device by using an unused SL transmission unit in the N SL transmission units through a HARQ process used for the unicast connection or the groupcast communication group. The second terminal device sends a HARQ feedback result to the first terminal device based on a decoding result. When the first terminal device has not received the HARQ feedback result or the received HARQ feedback result indicates that the data packet fails to be transmitted, the first terminal device retransmits the data packet by using a next unused SL transmission unit in the N SL transmission units. A HARQ feedback retransmission mechanism and a corresponding resource allocation method are introduced into SL transmission, to improve reliability of a data packet in the SL transmission.

摘要： Disclosed are a data edge protocol-based communication method and apparatus. The method may be performed through the following steps: A first communication apparatus sends a data edge protocol DEP session establishment request message to a second communication apparatus, where the DEP session establishment request me ssage is used to request to establish a DEP session between the first communication apparatus and a computing power, the DEP session is used to transmit data of a first application, the first communication apparatus, the second communication apparatus, and the computing power all have a function of a DEP layer, the DEP layer is located below a third layer of a wireless network protocol layer, and the DEP session is located at the DEP layer. The first communication apparatus receives configuration information of the DEP session from the second communication apparatus. In this method, direct data transmission between the terminal device and the first application on the computing power can be implemented by using the DEP session, thereby reducing a path for data exchange between the terminal device and the application. Therefore, compared with an existing edge computing technology, this method can further reduce a delay variation, and implement a same service while reducing network resource overheads.

摘要： This application provides a computation task processing method, a communication apparatus, and a wireless network architecture to reduce a processing delay of a computation task. The wireless network architecture includes a computation plane. The computation plane is connected to a control plane through a first interface, and is connected to a user plane through a second interface. The method includes: receiving, by the computation plane, a message of the computation task from a task source, where the task source may be at least one of the control plane, the user plane, or an application. The computation plane executes the computation task after receiving the message of the computation task. By deploying a computation plane in a wireless network, a terminal device can establish a connection to the computation plane deployed in the wireless network, implementing data exchange between the terminal device and the computation plane. In this way, a processing delay of a computation task can be effectively reduced.

摘要： Embodiments of this application provide a communication method and a related device. The method includes: User equipment obtains various conditions based on configuration information from a base station, and then performs path switching based on the various conditions. For example, a network device first sends the configuration information to the user equipment, and then the user equipment obtains a first condition based on the configuration information. Then, in a measurement process, the user equipment sends a measurement report to the network device when determining that the first condition is currently met. After obtaining the measurement report, the network device indicates at least one candidate relay device to the user equipment by using a path switch command. The user equipment determines one relay device in the at least one candidate relay device, and communicates with the network device or another network device through the determined relay device.

摘要： This application discloses a communication method, including: An access network device generates a candidate conditional handover configuration group, and sends the candidate conditional handover configuration group to a terminal, where the candidate conditional handover configuration group includes one or more candidate conditional handover configurations, and the one or more candidate conditional handover configurations correspond to a flight-related parameter of the terminal; and the terminal obtains a current flight parameter, and determines a target conditional handover configuration from the candidate conditional handover configuration group based on the current flight parameter, where the target conditional handover configuration is used to determine a second cell that the terminal expects to access. In this process, because the candidate conditional handover configuration group generated by the access network device to which a first cell belongs corresponds to the flight-related parameter, the terminal obtains the target conditional handover configuration in the candidate conditional handover configuration group based on a matching result between the current flight parameter and the flight-related parameter. In this way, accuracy of obtaining the target conditional handover configuration is improved, and efficiency of handover to the second cell is improved.
