The present invention discloses a method and a terminal for receiving and sending scheduling information, and relates to the field of communications technologies. The method comprises: obtaining, by a terminal, transmission mode information of each carrier of N carriers configured by a network device, where N is a natural number greater than 1; determining a set of candidate downlink control information DCI formats according to the transmission mode information, where the set of candidate DCI formats includes at least a first DCI format and a second DCI format, where a physical downlink control channel PDCCH corresponding to the first DCI format carries scheduling information of at least two carriers of the N carriers, and a PDCCH corresponding to the second DCI format carries scheduling information of one carrier of the N carriers; and receiving and detecting a PDCCH corresponding to each DCI format in the set of candidate DCI formats.
