A method for transmitting information, comprising following steps: determining, by a base station information of a group of terminals to be sent; and using, by the base station, within a set of resources of a group common physical downlink control channel, PDCCH, corresponding to the group of terminals, different subcarrier spaces to send the information of the group of terminals; wherein the information of the group of terminals is common information for all terminals in the group of terminals; wherein the different subcarrier spaces comprise subcarrier spaces used by terminals of the group of terminals during sending and receiving of data in a same slot, wherein resources using the different subcarrier spaces are orthogonal in a frequency domain, or the different subcarrier spaces comprise subcarrier spaces corresponding to each slot, wherein resources using the different subcarrier spaces are orthogonal in a time domain; wherein in response to the different subcarrier spaces comprising subcarrier spaces used by terminals of the group of terminals during sending and receiving of data in a same slot, the using, by the base station, within the set of resources of the group common PDCCH corresponding to the group of terminals, different subcarrier spaces to send the information of the group of terminals comprises: for any subcarrier space in the slot, using, by the base station, within a set of resources of a group common PDCCH corresponding to the subcarrier space, the subcarrier space to send the information of the group of terminals on the group common PDCCH; wherein in response to the different subcarrier spaces comprise subcarrier spaces corresponding to each slot, the using, by the base station, within the set of resources of the group common PDCCH corresponding to the group of terminals, different subcarrier spaces to send the information of the group of terminals comprises: for any slot, using, by the base station, within a set of resources of a group common PDCCH corresponding to the slot, a subcarrier space corresponding to the slot to receive and send the information of the group of terminals on the group common PDCCH. determining, by a base station information of a group of terminals to be sent;
