<p>Disclosed are a method, a system and a device for transmitting and detecting a PDCCH in a long term evolution-advanced system, which relate to the technical field of wireless communication, and are used for reducing the work load of a stand-alone-capable carrier to which an extension carrier or carrier segments are attached. In the present invention, a base station transmits a PDCCH on an extension carrier or carrier segments to schedule physical resources on the extension carrier or the carrier segments, and a user equipment uses a demodulation pilot signal DMRS to detect the PDCCH transmitted on the extension carrier or the carrier segments by the base station. Therefore, through the present invention, the physical resources on the extension carrier or the carrier segments are scheduled by the PDCCH transmitted on the extension carrier or the carrier segments, and the stand-alone-capable carrier does not need to schedule the physical resources on the extension carrier and/or the carrier segments bound to the stand-alone-capable carrier, thereby reducing the work load of the stand-alone-capable carrier to which the extension carrier or the carrier segments are attached.</p> |
