Abstract

The embodiment of the invention discloses a radio frequency interface controller, a communication method, a baseband chip and a communication system. The method includes: at least one set of input and output circuits, each set of input and output circuits includes: a first communication terminal, a second communication terminal, and a communication protocol circuit; the communication protocol circuit includes an input path and an output path, the The input path includes at least two types of input interface circuits, and the output path includes at least two types of output interface circuits, and each type of the input interface circuit or the output interface circuit is used to adapt to different radio frequency chips; The output path is used to send the baseband signal received through the first communication terminal to the second communication terminal through the currently adapted output interface circuit; the input path is used to transmit the baseband signal received through the second communication terminal The received radio frequency signal is sent to the first communication terminal through the currently adapted input interface circuit. The embodiment of the present invention can be compatible with different types of radio frequency chips.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication, and in particular to a radio frequency interface controller, a communication method, a baseband chip and a communication system. Background technique [0002] With the development of mobile communication technology, radio frequency communication has become a common communication method in people's daily life. People can make calls, send text messages and network through radio frequency communication. [0003] For example, when a user uses a mobile terminal to connect to the Internet, the baseband chip of the mobile terminal sends a baseband signal to the radio frequency chip, and the radio frequency chip forwards the baseband signal to the antenna, and the antenna sends it to the base station, so that the mobile terminal requests data from the server. When the antenna captures the fed-back baseband signal and forwards it to the baseband chip for processing through the radio ...

Problems solved by technology

However, the update speed of RF chips is fast, and the communication protocols required by different RF chips are different. It is difficult for baseband chips to quickly adapt to different types of RF chips to realize RF communication.
