1. A method, applied for a terminal device, comprising:
receiving first configuration information from a first network device or a second network device, wherein the first configuration information comprises first time information;
determining based on the first configuration information that the terminal device is allowed to send assistance information of the terminal device to the first network device through a signaling radio bearer 3 (SRB3) within a time range corresponding to the first time information, wherein the terminal device is connected to at least two network devices, and the first network device is a secondary network device in the at least two network devices, the second network device is a master network device in the at least two network devices; and
sending the assistance information to the first network device through the SRB3, wherein the assistance information indicates a configuration expected by the terminal device or service information of the terminal device, wherein the assistance information comprises one or any combination of the following:
a quantity of secondary cells corresponding to the terminal device;
a quantity of antenna ports of the terminal device;
a bandwidth of each secondary cell corresponding to the terminal device;
a connected-discontinuous reception (C-DRX) configuration or parameter expected by the terminal device;
an application type of the terminal device;
a size of a data packet transmitted by the terminal device;
a scheduling mode expected by the terminal device;
a search space expected by the terminal device;
a scheduling format expected by the terminal device; or
a slot format expected by the terminal device.
