Abstract

Provided are a method for configuring multiple carriers, a terminal device, and a network device. The method includes that: a terminal device sends first information and/or second information to a network device, the first information being configured to indicate a radio frequency architecture capability of the terminal device, and the second information being configured to indicate a radio frequency link capability of the terminal device. By the embodiments of the disclosure, a network device may configure multiple carriers for a terminal device based on information reported by the terminal device.
