Abstract: 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.

Abstract: Embodiments of the present disclosure provide a data transmission method, user equipment, and an access network device. UE transmits air interface data to an access network device by using a serving cell set including at least two core serving cells that can independently serve the UE to transmit data, and initiates an RRC connection re-establishment process to the access network device only when detecting that all core serving cells in the serving cell set are unavailable. Data transmission is performed by using an available serving cell to the greatest extent. In other words, data transmission can be performed by using any available core serving cell, to reduce the dependence of data transmission between serving cells and minimize possibility of data transmission interruption, thereby improving data transmission robustness.

Abstract: Embodiments of this application disclose a communication method and a communications apparatus. A source base station instructs a terminal to hand over from the source base station to a target base station, and sends, to the terminal, configuration information of a second connection required for communication between the terminal and the target base station. The terminal maintains a first connection for communication with the source base station, and establishes the second connection for communication with the target base station based on the configuration information of the second connection. The solutions in the embodiments of this application reduces latency in a handover process.

Abstract: Embodiments relate to the field of communications technologies, and specifically, to a mobility management method, an apparatus, and a system. Embodiments of the present invention provide the mobility management method, the apparatus, and the system. When a primary cell of user equipment is changed, a change of the primary cell is performed through modification but not through conventional handover, so that data transmission is uninterrupted when the primary cell is changed.

Abstract: A communication method includes receiving, by a terminal device comprising a processor, indication information from a master node. The indication information is used to indicate that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second signaling radio bearer (SRB) is a first key. The first key is used for signaling transmission performed between the terminal device and the master node by using a first SRB. The first secondary node and the master node share one central unit. The communication method also includes determining, by the terminal device, based on the indication information, that the first key is used for signaling transmission performed between the terminal device and the first secondary node by using the second SRB.

Abstract: The present disclosure relates to communication methods and apparatus. On one example method, a terminal device obtains measurement results of N cells, where the N cells include M non-public network cells, where N is an integer greater than or equal to 1, and where M is an integer greater than or equal to 0. The terminal device determines, based on the measurement results of the N cells and measurement result offset values corresponding to H first cells in the N cells, a target cell on which the terminal device is to camp, where H is an integer greater than or equal to 1, and where H≤N.
