Abstract
A multiway switch, a radio frequency system, and a communication device includes ten T ports and four P ports. The ten T ports include two first T ports, and each of the two first T ports is coupled with all the four P ports. The antenna system includes four antennas corresponding to the four P ports. The multiway switch is coupled with the radio frequency circuit and the antenna system to implement a function of transmitting a sounding reference signal (SRS) through the four antennas in turn.
