Abstract: This application relates to the communications field, and in particular, to a data transmission method, an apparatus, and a system. In the data transmission method, a base station determines a transmission policy, where the transmission policy is used for contention-based uplink data transmission or non-contention based uplink data transmission; and sends the transmission policy to a terminal. The terminal receives the transmission policy sent by the base station, and sends uplink data to the base station based on the transmission policy. With a solution in this application, the base station can determine an appropriate transmission policy based on a network status, and send the transmission policy to the terminal, and the terminal can use, based on the transmission policy, an appropriate transmission mode to send uplink data to the base station, so that transmission efficiency is improved.

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.

Abstract: The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.
