Abstract
A terminal device includes a first antenna, a second antenna, a first channel electrically connected to the first antenna, and a second channel electrically connected to the second antenna. The first channel includes at least two first transmitting branches used to transmit carrier signals for carrier aggregation (CA). The second channel includes a receiving branch electrically connected to the second antenna and a receiving filter electrically connected to the receiving branch. The receiving branch may be used to receive CA signals through the second antenna, and the receiving filter may be used to filter the CA signals to obtain the carrier signals for CA.
