Abstract: This application provides a transmission mode switching method and an apparatus. When UE is in a connected state, if an uplink service volume of the UE within a first detection time is less than a first threshold, the UE switches a state from the connected state to an ecology conservation optimization; or switches, in the connected state, a transmission mode from an uplink scheduling-based transmission mode to an uplink contention-based transmission mode.

Abstract: An access method and a communication apparatus are provided. The method includes: A terminal device receives first indication information from a first network device, receives access indication information from a second network device, and initiates access to a target cell of the second network device based on the access indication information. The first indication information indicates the terminal device to initiate the access to the target cell of the second network device based on the access indication information from the second network device. After being indicated to receive the access indication information from the second network device, the terminal device initiates the access to the target cell of the second network device.

Abstract: This application provides a communication method and apparatus, so that a terminal device reports an RLF report related to whether link recovery for an MCG succeeds. The terminal device separately communicates with a first network device and a second network device, where the first network device manages a first MCG, the second network device manages a first SCG, and an MCG link recovery function is configured for the first SCG. After determining that a radio link failure RLF occurs in the first MCG, the terminal device sends a first RLF report to a third network device, where the first RLF report is related to whether link recovery for the first MCG succeeds.

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.
