A method for allocating PDCCH channel, includes: dividing the physical downlink control channel (PDCCH) into two sets according to a scheduled PDCCH format; setting a control channel element (CCE) from the allocable control channel elements as a constant beginning CCE for each set; allocating CCE for each set of PDCCH sets, beginning respectively from the said constant beginning CCE. The embodiment of the invention also provides an indicating method for allocating ACK/NACK channel, a device for allocating PDCCH, a device for sending ACK/NACK channel, a device for receiving ACK/NACK channel, a base station and a terminal using said device for sending ACK/NACK channel and said device for receiving ACK/NACK channel. With this embodiment, it is practical to indicate recessively the allocation of ACK/NACK channel, and to reduce the waste of communication channel resources. |
