A frame format configuration method, comprising: receiving, by a terminal device, first configuration information of a frame format configuration and that is received from a network device, wherein the first configuration information is used for determining locations, in a radio frame, of a full-duplex subframe and a normal subframe in the radio frame; and determining, by the terminal device, the locations, in the radio frame, of the full-duplex subframe and the normal subframe in the radio frame based on the received first configuration information, wherein the full-duplex subframe is a subframe in which the network device can simultaneously perform downlink transmission and uplink reception in the radio frame, and the normal subframe is a subframe in the radio frame other than the full-duplex subframe; wherein the first configuration information comprises N pieces of first indication information arranged in sequence, wherein N is a positive integer and is a quantity of subframes comprised in one radio frame, and each piece of first indication information corresponds to one subframe in the radio frame and is used for indicating whether the corresponding subframe is the full-duplex subframe or the normal subframe; and the determining the locations, in the radio frame, of the full-duplex subframe and the normal subframe in the radio frame based on the received first configuration information comprises: separately determining based on the N pieces of first indication information arranged in sequence, whether the subframe corresponding to each piece of first indication information is the full-duplex subframe or the normal subframe, and determining the locations of the full-duplex subframe and the normal subframe in the radio frame in order of the N pieces of first indication information; and wherein after the determining the locations, in the radio frame, of the full-duplex subframe and the normal subframe in the radio frame based on the received first configuration information, the method further comprises: separately performing, by the terminal device, radio measurement on the full-duplex subframe and the normal subframe to obtain interference level values of the two types of subframes used for link adaptation. receiving, by a terminal device, first configuration information of a frame format configuration and that is received from a network device, wherein the first configuration information is used for determining locations, in a radio frame, of a full-duplex subframe and a normal subframe in the radio frame;
