METHOD OF EFFICIENT TRANSMITTING A RADIO CHANNEL USING A COORDINATION FIELD

摘要

A method for efficiently transmitting a radio channel using a coordination field is provided to increase data throughput and data communication by efficiently receiving a control channel through a coordination field. A coordination field including multi carrier supporting information is transmitted through a reference carrier(S1420). A PDCCH(Physical Downlink Control CHannel) is transmitted according to the multi carrier supporting information(S1450). A PDSCH(Physical Downlink Share CHannel) is transmitted according to information included in the PDCCH(S1460). The reference carrier includes control information about a multi carrier. The coordination field is transmitted as a CCE(Control Channel Element) unit according to each sub frame. The coordination field includes indication information of a carrier allocated to a specific terminal and indication information of a blind decoding domain.
