METHOD FOR EFFICIENTLY TRANSMITTING PHYSICAL CHANNEL IN MULTI-CARRIER AGGREGATION STATE TO SUPPORT BROADBAND

摘要

PURPOSE: A method for efficiently transmitting a physical channel in a multi-carrier aggregation state to support a broadband is provided to eliminate a need of monitoring a control area of all downlink component carriers in a cross carrier scheduling state, thereby reducing a blind decoding overhead of a terminal. CONSTITUTION: A terminal receives uplink authentication information from a base station through a first downlink component carrier. Data is transmitted to the base station through an uplink resource that the uplink authentication information indicates. Feedback information is received from the base station through the first control channel of the first downlink component carrier. The feedback information indicates whether the transmitted data has an error. The upward link resource is not connected to the first downlink component carrier.
