摘要： Embodiments of this application disclose an operator processing method and a computer device, which may be applied to the field of artificial intelligence, and may be specifically applied to a dynamic shape scenario. The method includes: A real-time shape of any to-be-output first tensor can be obtained by combining in real time one or more micro-operators in a micro-operator library that is constructed in advance. Then, a micro-operator included in one combination is selected (for example, a combination with optimal performance is selected) for execution because different combinations have different performance. Micro-operators in the micro-operator library are pre-compiled. Therefore, a compiler is not needed. This reduces compilation overheads, and avoids excessively high compilation overheads of a just-in-time compilation technology at runtime. In addition, shapes of the micro-operators are fixed and different, and are used as a "basis" of "shape space". Therefore, any shape may be a combination of the one or more micro-operators in the micro-operator library, and programmability is high in the dynamic shape scenario. In addition, a quantity of micro-operators in the micro-operator library is limited, and a size of memory space is small.

摘要： A time synchronization method and an apparatus are disclosed. The method includes: receiving, by a terminal device, a first time sent by an access network device; obtaining a first transmission delay; obtaining a fourth time based on the first transmission delay and the first time; and synchronizing a time of the terminal device based on the fourth time. In this way, when the terminal device synchronizes the time of the terminal device, the first transmission delay is introduced, so that a time error of air interface transmission can be effectively avoided, and accuracy of time synchronization can be improved. In addition, the time synchronization method has relatively strong applicability, and may be applicable to terminal devices in different states, for example, an idle state, a connected state, and a deactivated state.

摘要： Embodiments of this application provide a method and an apparatus for avoiding failure of transmitting consecutive data packets, and relate to the communications field. The method includes: maintaining, by a first access stratum entity of a transmit end, a transmission status of a previous data packet of the first access stratum entity, where the transmission status includes transmission success, transmission failure, or packet loss. If the transmission status of the previous data packet is transmission failure, the transmit end adjusts a transmission parameter of a current data packet. The method provided in the embodiments of this application ensures that in a data transmission process, a case in which two consecutive application layer data packets both fail to be transmitted does not occur. This improves data transmission reliability.

摘要： This application provides a communication method and a communications apparatus. The communication method includes: determining, by a transmit end device, a first moment, where the first moment is a moment when a receive end device needs to deliver first data to an upper layer of a communications protocol layer of the receive end device; and sending, by the transmit end device, first indication information and the first data, where the first information is used to instruct the receive end device to deliver the first data to the upper layer of the communications protocol layer of the receive end device at the first moment. The receive end device can be supported in determining the first moment based on the first indication information and delivering the first data to the upper layer of the communications protocol layer at the first moment. Therefore, the receive end device can be supported in performing an action corresponding to the first data in the upper layer of the communications protocol layer at the first moment, thereby preventing a transmission latency from affecting execution by the receive end device of an action corresponding to the data.
