Abstract: A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.
