Abstract: A method of cell handover, a method for determining an uplink transmit power, and an apparatus are provided, to strengthen control of a network device over a terminal device. The cell handover method includes: receiving, by a terminal device, an early handover command sent by a network device, where the early handover command is used to instruct the terminal device to determine whether to perform a cell handover; measuring, by the terminal device, a downlink signal sent by the network device and/or a downlink signal sent by another network device, and determining, based on an obtained measurement report and a handover condition carried in the early handover command, whether to perform the cell handover; and executing, by the terminal device, a handover command to hand over from a current serving cell to a target cell if the terminal device receives the handover command sent by the network device.

Abstract: This application provides example uplink carrier handover methods, network devices, and terminal devices. One example method includes obtaining, by a network device, target measurement information, where the network device communicates with a terminal device in a current cell by using a first uplink carrier and a second uplink carrier. The network device can then determine, based on the target measurement information, whether the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier. In response to determining that the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier, the network device can send handover instruction information to the terminal device.

Abstract: Embodiments of the present disclosure relate to a radio resource control (RRC) message processing method, apparatus, and system. The method includes: establishing, by a first serving node, a connection to a first anchor node, and establishing, by the first anchor node, a connection to a mobility management entity MME; receiving, by the first serving node, a radio resource control RRC message sent by a first user equipment (UE), where the RRC message includes an RRC message carried by a signaling radio bearer (SRB1) or an RRC message carried by an SRB2; and sending, by the first serving node, the RRC message to the first anchor node.

Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.

Abstract: Embodiments of the present invention provide a radio bearer processing method, user equipment, and a base station. The method includes: suspending, by user equipment, data transmission of a bearer on a second base station; and sending, by the user equipment, a suspend indication to a first base station, where the suspend indication is used to indicate that the user equipment has suspended the data transmission of the bearer on the second base station. When the data transmission of the bearer on the second base station is resumed, the related protocol entity does not need to be re-established, thereby improving utilization of radio bearer resources.
