An objective of the present invention is to provide a method, apparatus, and equipment for determining device channel resources of a user equipment in an LTE-TDD system. The TDD system performs resource scheduling to the user equipment using an enhanced physical downlink control channel, and a physical uplink control channel used includes channel resource(s) for feeding back a hybrid automatic repeat request of a physical downlink shared channel as scheduled by the enhanced physical downlink control channel, when the number of downlink subframes as fed back in one uplink subframe may be more than one, the channel resource(s) is divided into a plurality of channel regions based on the number of downlink subframes having the enhanced physical downlink control channel set thereon currently, or based on the potential highest number of downlink subframes having the enhanced physical downlink control channel set thereon. The present application obtains the device channel resource(s) occupied by the present user equipment in at least one channel region of the plurality of channel regions. The present invention enables the user equipment to feed back ePDCCH.
