Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a radio frequency circuit, a terminal device and a method for transmitting radio frequency signals. Background technique [0002] With the widespread application of terminal devices such as smart phones, smart phones can support more and more applications, and their functions are becoming more and more powerful. supplies. The terminal equipment in the fourth-generation 4G mobile communication system generally adopts a single-antenna or dual-antenna radio frequency system architecture. At present, the terminal equipment supporting the radio frequency system architecture of 4 antennas is proposed in the new air interface NR system of the fifth-generation 5G mobile communication system. [0003] SRS (Sounding Reference Signal, sounding reference signal) rotation is an important technology of 5G, which means that the terminal sends SRS information on differen...
