Abstract: This application provides a failure processing method, a handover method, a terminal device, and a network device, to provide a manner in which a terminal receives an RRC configuration of a secondary network device and feeds back an RRC configuration failure. The method includes: directly receiving, by a terminal device, a first RRC configuration of a secondary network device from the secondary network device; and when the first RRC configuration fails, sending, by the terminal device, first indication information to a primary network device to indicate that the first RRC configuration fails. In addition, when the first RRC configuration fails, the terminal reports one piece of first indication information to the primary network device to indicate that the first RRC configuration fails.

Abstract: Example transmission rate control methods and apparatus are described. One example method includes obtaining a user equipment aggregate maximum bit rate (UE-AMBR) by a master base station. The master base station determines, based on the UE-AMBR, a first UE-AMBR used for the master base station and a second UE-AMBR used for a secondary base station. The master base station sends the second UE-AMBR to the secondary base station, and sends instruction information used to instruct the secondary base station to control data splitting for the master base station to the secondary base station. In this application, a transmission rate between each base station and a UE is controlled by allocating a UE-AMBR.

Abstract: The present application describes a data processing method used for implementing data transmission between multiple carriers and a HARQ entity. A terminal receives mapping relationship information sent from a base station, where the mapping relationship information is used to indicate a mapping relationship between a HARQ entity of the terminal and a frequency resource configured by the base station for the terminal. The terminal determines the frequency resource. The terminal determines a HARQ entity corresponding to the frequency resource according to the mapping relationship information and processes a HARQ data block transmitted on the frequency resource by using the HARQ entity. Therefore, carrier communication channels for real-time transmission between the base station and the terminal are increased, to improve transmission efficiency.

Abstract: A configuration method is provided in a communications system. The communications system includes a master node and a secondary node that jointly provide a service for a terminal. The method includes: the secondary node generates configuration information for a signaling radio bearer (SRB), where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal; and sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal, thereby improving efficiency in radio resource management on the secondary node.
