Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A network device determines energy saving information of a first cell, where the energy saving information indicates a compensation value corresponding to a first energy saving state, and when the first cell is in the first energy saving state, the compensation value is used to compensate a measurement value of an SSB associated with the compensation value; and sends the energy saving information to a terminal device. According to the method, the network device may perform an energy saving operation on the SSB (for example, reducing a transmit power of the SSB), and send the energy saving information of the first cell to the terminal device.

Abstract: This application discloses a communication method and apparatus. The method includes: A terminal device receives, in a first cell, configuration information of at least one candidate cell from an access network device; and selects a second cell when a radio link of the first cell meets a first condition (that is, a problem occurs on the radio link of the first cell). If the second cell belongs to the at least one candidate cell, the terminal device is handed over from the first cell to the second cell, and communicates with the access network device in the second cell based on configuration information of the second cell.

Abstract: This application provides a data transmission method and a communication apparatus. The data transmission method includes: A terminal device receives first information from a first access network device, where the first information indicates the terminal device to be handed over and connected to a second access network device. The terminal device sends a first data packet to the second access network device after the terminal device successfully accesses the second access network device, where the first data packet is a data packet that has been sent by the terminal device to the first access network device before the terminal device successfully accesses the second access network device.

Abstract: This application discloses a cell camping method and an apparatus. The method includes: After a terminal device camps on a first cell, a network device may send a first message to the terminal device, where the first message includes information about a second cell, the first cell corresponds to a first CC, and the second cell corresponds to a second CC; after receiving the first message, the terminal device sends a second message to the network device, where the second message may indicate the first cell and/or the second cell, or the second message may include measurement information of the first cell and/or the second cell; and the network device may determine, based on the second message, that the terminal device camps on the first cell or the second cell. This ensures network load balancing between different cells.

Abstract: The present disclosure relates to radio resource control (RRC) reestablishment methods and apparatuses. In one example method, a terminal device selects a target cell, where the target cell supports an expected network slice. The terminal device sends an RRC reestablishment request message by using the target cell. The expected network slice may include a network slice that the terminal device expects to access, or a network slice corresponding to a PDU session established by the terminal device by using a last serving access network device of the terminal device. The terminal device may select the target cell within a preset time period. For example, the terminal device starts a first timer when the terminal device starts selecting the target cell, and selects the target cell during running of the first timer. The first timer may be specific to one or more network slices or all network slices.

Abstract: Example communication methods and apparatus are described. One example method includes obtaining a first compression dictionary by a compression node. The compression node compresses a first data packet by using a first compression dictionary, and sends a first compressed data packet to the decompression node. The compression node compresses a second data packet by using the first compression dictionary, and sends a second compressed data packet to the decompression node.
