摘要： The embodiments of the present invention provide a base station, a network controller, and a forward handover method. The base station includes a first base station to which a target cell of user equipment belongs and a second base station to which the user equipment belongs, where the second base station includes: a second processor and a second transceiver, the second processor generates a forward handover indication, and the second transceiver sends the forward handover indication to the first base station, so that when receiving an RRC re-establishment request message of the user equipment, the first base station acquires context information of the user equipment from the second base station according to the forward handover indication. In the foregoing manner, the user equipment can independently select a target cell, and overcomes a disadvantage of violating a basic criterion in the prior art that mobility management is determined and controlled by a network.

摘要： Methods, systems, and apparatus for communications are provided. In one aspect, a communication method including: determining, by a first communications apparatus, buffer latency information, and sending, by the first communications apparatus, the buffer latency information. The buffer latency information is determined based on a buffer latency of one or more data packets. The buffer latency indicates one of a time interval between a time point at which a data packet arrives at an access stratum (AS) and a time point at which a corresponding buffer status report (BSR) is sent, or a time interval between a time point at which a data packet arrives at an AS and a time point at which a corresponding uplink grant is received.

摘要： This application provides a method for activating a secondary cell, a communications apparatus, and a network device. The method includes: after receiving an activation command for a secondary cell that is sent by a network device, sending a first uplink signal to the network device using a first period from a first time unit; determining a second time unit; and sending a second uplink signal to the network device using a second period or based on scheduling of the network device after the second time unit, where the second period is greater than the first period. According to the method, in a secondary cell activation process, an uplink signal can be sent at a relatively short period thereby resolving a problem that network resource consumption and an activation delay are unbalanced in the secondary cell activation process, and improving data transmission efficiency and user experience.

摘要： The present invention relates to a beam-based multi-connection communication method, a terminal device, and a network device. The method may include the following: Based on a multi-beam connection established between a terminal and a base station, the terminal further selects a dedicated message beam from a common message range of the base station based on a measurement result of an uplink pilot, or the base station selects a dedicated message beam from a common message range of the base station based on a measurement result of a downlink pilot; and the terminal or the base station chooses to delete at least one established beam connection. By selecting and deleting a multi-beam connection between the terminal and the base station, a high-quality beam connection is maintained, and interruption of data transmission between the base station and terminal is avoided, thereby ensuring normal communication between the base station and the UE.
