1. A method, applied in a network device, the method comprising:
sending a first message to a terminal device, wherein the first message carries information comprising a carrier aggregation band combination range, and the carrier aggregation band combination range comprises at least one of a requested maximum bandwidth of carriers, or a requested maximum quantity of the carriers; and
receiving a carrier aggregation capability and baseband capabilities from the terminal device;
wherein the carrier aggregation capability meets the carrier aggregation band combination range, the carrier aggregation capability comprises a quantity of carriers supported by the terminal device and a bandwidth of a carrier supported by the terminal device, and
wherein the baseband capabilities meet a baseband capability range, the baseband capability range is based on the carrier aggregation band combination, and the baseband capabilities comprises a baseband capability with regard to one class of carrier information, and the carrier information comprises a quantity of carriers and a bandwidth of a carrier, and a baseband capability with regard to one class of carrier information comprises a first multiple-input multiple-output (MIMO) capability, and the first MIMO capability indicates a quantity of MIMO layers supported by the terminal device.
