Provided are a method for transmitting information and a device. The method comprises: a receiving end device receiving, within a first time unit, first information sent by a sending end device; and the receiving end device sending, within a second time unit, second information corresponding to the first information to the sending end device, wherein the duration of the first time unit is different from that of the second time unit. By means of the method for transmitting information in the embodiments of the present invention, when different transmission time intervals are used for an uplink and a downlink or a plurality of types of transmission time intervals are used for a communication system, rational scheduling and a time sequence fed back can be determined for devices at a receiving end and a sending end so as to ensure normal transmission of the information.
