• a second transceiver, which receives a first radio signal and a second radio signal respectively in a first time-frequency resource block and a second time-frequency resource block;
• wherein any two of the N time sub-windows are orthogonal, any two of the N time sub-windows comprise equal numbers of multicarrier symbols;
• the first radio signal and the second radio signal respectively carry two repetitions of transmission of the first bit block;
• a given time sub-window is one of the N time sub-windows, the given time sub-window comprises M periods, and any of the M periods comprises multiple consecutive multicarrier symbols, M being a positive integer and the M being greater than 1;
• the given time sub-window comprises a DL/UL switching point or a time-domain unit boundary, the time-domain unit comprising a slot, and a repetition of transmission of the first bit block is performed during each of the M periods;
• the first time-frequency resource block belongs to a time sub-window of the N time sub-windows in time domain, while the second time-frequency resource block belongs to a time sub-window of the N time sub-windows in time domain;
• the first radio signal corresponds to a first parameter, while the second radio signal corresponds to a target parameter, the target parameter being either the first parameter or a second parameter, and whether the first time-frequency resource block and the second time-frequency resource block belong to a same time sub-window of the N time sub-windows is used to determine whether the target parameter is the first parameter or the second parameter;
