Abstract

The embodiment of the invention provides a radio frequency circuit, terminal equipment and a radio frequency signal sending method. The radio frequency circuit comprises a first signal transmitter and a second signal transmitter; a first radio frequency transmitting module which is connected with the first signal transmitter and is used for transmitting a signal of the first communication system network and a signal of the second communication system network; a second radio frequency transmitting module which is connected with the second signal transmitter and is used for transmitting the signal of the second communication system network; a first antenna group which is connected with the first radio frequency transmitting module; a second antenna group which is connected with the second radio frequency transmitting module; and a first switch assembly, wherein one end of the first switch assembly is arranged between the first radio frequency transmitting module and the first signal transmitter, the other end of the first switch assembly is arranged between the second radio frequency transmitting module and the second signal transmitter, and the first switch assembly is used for selecting a signal transmitting path of the second communication system network. The uplink and downlink data transmission performance of terminal equipment in an NR system is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a radio frequency circuit, a terminal device and a method for sending radio frequency signals. Background technique [0002] With the popularization and application of smart phones and other terminal devices, smart phones can support more and more applications and more powerful functions. Smart phones are developing in a diversified and personalized direction, becoming an indispensable electronic device in users' lives. supplies. 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 new air interface NR system of the fifth-generation 5G mobile communication system proposes a terminal equipment that supports a 4-antenna radio frequency system architecture. [0003] SRS (Sounding Reference Signal, sounding reference signal) rotation is an ...
