Abstract
A method and device for transmitting information, for solving the problem that at present there is no solution configured to use a group common physical downlink control channel (PDCCH) to transmit information related with a group of terminals. In the embodiments of the present disclosure, a base station determines information of a group of terminals to be sent; and the base station uses, within a set of resources of a group common PDCCH corresponding to the group of terminals, a fixed subcarrier space or different subcarrier spaces to send the information of 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 or, the different subcarrier spaces comprise subcarrier spaces corresponding to each slot;
- wherein in response to that 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, 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;
- or,
- wherein in response to that 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.
