Embodiments of the present invention provide an information transmission method, a base station, and a user equipment. The method comprises: in a subframe, a network side device sending a piece of downlink control information to a user equipment, the downlink control information comprising a combination of multiple pieces of resource allocation information and at least one resource unit mapping and quasi-co-site indicator; and the network side device sending, to the user equipment, a physical data sharing channel scheduled by the downlink control information. By means of the embodiments of the present invention, a combination of multiple pieces of resource allocation information and at least one resource unit mapping and quasi-co-site indicator can be provided to a user equipment in a subframe, so as to provide, for a multipoint transmitted resource, downlink control information for decoding a physical data sharing channel, and therefore, a DPS technical solution in a frequency division mode can be used.
