FIG8 is a structural block diagram of a network side device according to an embodiment of this application. The network side device 800 shown in FIG8 includes a processor 801, a memory 802, and a transceiver 803. It may be understood that, in addition to the processor 801, the memory 802, and the transceiver 803 shown in FIG8, the network side device 800 should further include some necessary apparatuses such as an antenna, a cyclic prefix remover, and a fast Fourier transformation processor. To avoid redundancy, the foregoing apparatuses are not shown in FIG8.  FIG7 is a structural block diagram of a terminal device according to an embodiment of this application. The terminal device 700 shown in FIG7 includes a processor 701, a memory 702, and a transceiver 703. It may be understood that, in addition to the processor 701, the memory 702, and the transceiver 703 shown in FIG7, the terminal device 700 should further include some necessary apparatuses such as an antenna, a display, and an input apparatus. To avoid redundancy, the foregoing apparatuses are not shown in FIG7.
