摘要： This application provides a communication method and apparatus. The method includes: a terminal device receives conditional handover configuration information from a first network device, where the configuration information is used to configure a trigger condition of a conditional handover, and the first network device is a network device to which a serving cell currently accessed by the terminal device belongs. The terminal device determines a first target cell based on the conditional handover configuration information, where the first target cell is a cell in at least one candidate target cell that satisfies the trigger condition.

摘要： Embodiments of this application provide a data transmission method and device. The method includes: obtaining, by a first access network device, a first message from a second access network device, where the first message requests context information of a terminal device; and sending, by the first access network device, a data packet to the second access network device. The first access network device is a corresponding access network device of the terminal device before the re-establishment procedure, and the second access network device is a corresponding access network device when the terminal device initiates the re-establishment procedure.

摘要： Embodiments of this application provide an information transmission method, an apparatus, and a system. A first network device sends, to a terminal device, conditional handover configuration information that includes information about candidate cells and a handover trigger condition; after receiving the conditional handover configuration information and performing a conditional handover, the terminal device sends, to a second network device, a first failure cause value corresponding to a candidate target cell and/or a second failure cause value corresponding to a to-be-determined cell during the conditional handover; and the second network device receives the first failure cause value and/or the second failure cause value from the terminal device, and sends the first failure cause value and/or the second failure cause value to the first network device.

摘要： This application discloses a communication method and a communications apparatus, and relates to the communications field, to reduce power consumption of a terminal. The communication method includes: determining, by a first network device, first information, where the first information includes type information of a synchronization signal block, and the type information of the synchronization signal block is used to indicate that the synchronization signal block is a cell-defined synchronization signal block or a non-cell-defined synchronization signal block; and sending, by the first network device, the first information to a second network device. Embodiments of this application are applied to an indication of the cell-defined or non-cell-defined synchronization signal block.
