Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a communication device performs listen before talk (LBT) detection. The communication device sends first information based on a target event, where the first information includes detection information of the LBT detection. The target event includes any one of that the LBT detection has a potential risk, that a communication process between the communication device and a network device has a potential risk, that the LBT detection fails, and that the communication process between the communication device and the network device fails. The communication process between the communication device and the network device is performed based on the LBT detection.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A terminal receives first application layer measurement configuration information from a first base station; performs quality of experience QoE measurement based on the first application layer measurement configuration information; receives a first message from a second base station, where the first message indicates whether to retain the first application layer measurement configuration information; and continues to perform QoE measurement when the first message indicates to retain the first application layer measurement configuration information; and/or releases the first application layer measurement configuration information when the first message indicates to not retain the first application layer measurement configuration information. This can reduce overheads, for example, signaling overheads or storage overheads, of application layer measurement configuration, or improve accuracy of an application layer measurement result for a specific service.

Abstract: This application provides a communication method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information includes a common timing advance of at least one candidate cell, and the first indication information is used to inform the terminal device that the at least one candidate cell is in a handover allowed state; and the terminal device sends a random access preamble to a target candidate cell based on a first timing advance, where the target candidate cell is one of the at least one candidate cell, and the first timing advance is a common timing advance of the target candidate cell. According to the method provided in this application, the UE can send the preamble more accurately in a handover scenario.

Abstract: A method includes receiving a first message from a first master node. The first message includes an identifier of a first candidate primary secondary cell (PSCell) or an identifier of first configuration information of the first candidate PSCell. The first candidate PSCell is included in both a first PSCell list and a second PSCell list. Alternatively, the first message includes delta configuration information of a second candidate PSCell in the second PSCell list. The first configuration information of the first candidate PSCell includes an addition/change condition and a configuration of the first candidate PSCell. The first PSCell list includes one or more candidate PSCells configured by the first master node for a terminal. The second PSCell list includes one or more candidate PSCells configured by a second master node for the terminal. The method also includes adding a target PSCell or changing from an original PSCell to the target PSCell.

Abstract: A handover method and a communication apparatus. A terminal device receives a first message, where the first message includes information about N candidate cells, the N candidate cells include N1 candidate cells and N2 candidate cells, the N1 candidate cells include a cell for which no conditional handover CHO execution condition information is configured, the N2 candidate cells include a cell for which the CHO execution condition information is configured, N and N2 are integers greater than 1 or equal to 1, and N1 is an integer greater than 0 or equal to 0. In a process of attempting to hand over from the source cell to the target cell, the terminal device maintains an RRC connection and/or data transmission with the source cell. Therefore, handover reliability is improved, a handover latency is reduced, and overall system performance is improved.

Abstract: This application provides a paging method and apparatus. The method includes: A first device receives a first paging message, where the first paging message includes a first list, and the first list includes an area identifier of at least one cell. The first device determines a first cell, where an area identifier of the first cell at a first moment is different from an area identifier of the first cell at a second moment, the first moment is a current moment, and the second moment is earlier than the first moment. When the area identifier of the first cell at the first moment does not belong to the first list, the first device stops paging a terminal device in the first cell. According to the foregoing technical solutions, the first device may effectively page the terminal device, to reduce signaling overheads of the first device, and save power.
