Provided in an embodiment of the present invention is a system channel detection method, the system comprising N types of sub-carriers for channel detection, N being an integer greater than 2, the method comprising: a UE acquires in advance a transmission comb parameter thereof via an RRC signaling; the UE determines comb values of each port of the UE according to the transmission comb parameter; the UE determines, according to the comb value of each port, the type of a sub-carrier corresponding to each port; according to an SRS pilot frequency sequence corresponding to the UE and a cyclic shift value of each port, determining the SRS pilot frequency sequence corresponding to each port; and according to the sub-carrier of the type corresponding to each port, transmitting the SRS pilot frequency sequence corresponding to the port. Also provided in the embodiment of the present invention is a system channel detection device. The embodiment of the present invention increases the number of the ports of the UE capable of simultaneously supporting the system during a channel detection. |
