Abstract: 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.

Abstract: 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.

Abstract: The method may include: after receiving, through a first interface or a second interface, resource allocation information of a neighboring cell of a serving cell in which UE is located, a network device may allocate a resource to the UE based on the resource allocation information of the neighboring cell, so as to prevent the UE from using a same resource as UE located in the neighboring cell, and reduce interference to the neighboring cell; or allocate, to the UE, a resource with relatively small interference to the UE, so as to reduce interference of the neighboring cell to the UE. The first interface is an interface that performs communication by using a UE-to-UE communications technology. The second interface is an interface that performs communication by using a UE-to-network device communications technology.
