Embodiments of the present invention provide an information transmission method, including: determining, by a user equipment (UE), a first subframe; configuring the UE to send a first uplink signal in the first subframe; determining, by the UE, that the first uplink signal is a first type of uplink signal, where the first type of uplink signal occupies a first part of symbols of the first subframe, and the number of symbols included in the first part of symbols is less than the number of symbols included in the first subframe; and detecting, by the UE, a downlink control channel on a second part of symbols in the first subframe, where the first part of symbols and the second part of symbols do not overlap in time domain.
