Abstract: When triggering a handover request, a source network device requests a measurement indication from a target access network device using the handover request, where the measurement indication indicates the terminal device to measure a channel state of a target cell. In this way, the source network device sends the measurement indication to the terminal device using an RRC reconfiguration message. Then, the terminal device measures the specified channel state of the target cell based on the measurement indication, to obtain a measurement result, and then determines, depending on whether the measurement result meets a handover condition, whether to perform cell handover.

Abstract: Examples in this application provide a communication method and a communications apparatus. One example communication method includes determining to deactivate or activate a first synchronization signal and physical broadcast channel block (SSB), and sending a first request message to a second network device. Specifically, the first request message carries first indication information for indicating the first SSB, and when the first SSB is an SSB in the first network device, the first request message requests the second network device to update a state of the first SSB, and the second network device maintains information about at least one SSB in the first network device, or when an active first SSB is an SSB in the second network device, the first request message requests the second network device to activate the first SSB, and the first network device maintains information about at least one SSB in the second network device.

Abstract: The disclosure provides data transmission methods and apparatuses. One example method includes when the terminal device needs to perform the cross-network movement, the terminal device sends a message to a network element of a network accessed by the terminal device, to notify that the terminal device is to perform the cross-network movement from a source network to a target network. Therefore, during the movement of the terminal device, a network side pauses transmission of user plane data of the terminal device, and buffers data that is not sent before the terminal device performs the cross-network movement. After accessing the target network, the network side sends the buffered data to the terminal device.

Abstract: Embodiments of this application relate to the field of wireless communication technologies, and provide a communication method and apparatus, to improve accuracy of a positioning result and reduce a waste of resources of a network device. In the method, the network device may receive a positioning information request from a positioning server. The positioning information request may be used to request the network device to configure uplink positioning reference signal configuration information for a terminal device. The network device may send the uplink positioning reference signal configuration information and neighboring cell information to the positioning server. The neighboring cell information may include an identifier of one or more first neighboring cells and/or a measurement result of a measurement quantity corresponding to the one or more first neighboring cells. The first neighboring cell is a neighboring cell of the terminal device.

Abstract: Example grouping methods, apparatuses, and systems are provided. One example method includes receiving, by a central unit, a first interference intensity indication reported by at least one distributed unit. The central unit can then group the at least one distributed unit into at least one first distributed unit group based on the first interference intensity indication. The central unit can then send, to a controller, a distributed unit grouping indication and a second interference intensity indication that corresponds to the at least one first distributed unit group, where the distributed unit grouping indication is used to indicate the at least one first distributed unit group.
