A subframe processing method and device are disclosed. A terminal can determine a special subframe in a non-contiguous secondary carrier according to a maximum continuous channel occupancy duration and a channel listening duration of the non-contiguous secondary carrier, and a channel occupancy start reference time point and/or a channel listening start reference time point of the non-contiguous secondary carrier that are obtained, where the special subframe includes all or some gap symbols occupied by the channel listening duration, use all symbols except the gap symbols in the special subframe as symbols that can be occupied by a PDCCH and/or a PDSCH, and correspondingly receive or decode the PDCCH and/or the PDSCH in the special subframe according to the symbols that can be occupied by the PDCCH and/or the PDSCH.
