The present invention provides a radio frequency circuit, a terminal and a signal transmission control method, including: a first antenna and a second antenna; a first transceiver unit for transmitting signals in a first frequency band, and a second transceiver unit for transmitting signals in a second frequency band unit; a switching unit, connected with the first antenna to form a first transceiver channel for transmitting signals on the first frequency band and the second frequency band; connected to the second antenna to form a second channel for transmitting signals on the first frequency band and the second frequency band Transceiver channel; the switching unit works in the first state when the current network of the terminal is the first network, and connects the first transceiver unit and the second transceiver unit with the first transceiver channel and the second transceiver channel in one-to-one correspondence; at the terminal When the current network is the second network, it works in the second state, and connects the first transceiver unit or the second transceiver unit with the first transceiver channel and the second transceiver channel. The radio frequency circuit simultaneously transmits uplink signals through two transceiver channels to improve the uplink data transmission performance of the terminal.
Description
technical field [0001] The present invention relates to the communication field, in particular to a radio frequency circuit, a terminal and a signal transmission control method. Background technique [0002] With the rapid development of mobile communication technology, terminals such as mobile phones and tablet computers are becoming more and more popular, and have become an indispensable part of people's daily life. In the process of using a terminal, people have higher and higher requirements on the performance and functions of the terminal, especially the high-speed data transmission capability of the terminal. However, at present, during the working process of the terminal, because the network in its working frequency band cannot meet the requirements of high data rate and wide-area coverage at the same time, especially when the wide-area coverage of the network in the working frequency band of the terminal is poor, it will affect the terminal’s transmission. Uplink si...
