    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.

    Abstract: A method for receiving control channel and an apparatus in a wireless communication system are provided. The method includes transmitting, at a base station, information on a primary cell operating in a frequency division duplexing (FDD) mode and a secondary cell operating in a time division duplexing (TDD) mode, transmitting, at the base station, downlink scheduling information for downlink data, transmitting, at the base station, the downlink data in a first subframe according to the downlink scheduling information, and receiving, at the base station, control information corresponding to the downlink data on the primary cell, from a terminal. The control information is transmitted using a physical uplink control channel (PUCCH) format determined based on a type of the first subframe of the secondary cell.
