<p>PURPOSE: A control channel allocation method and an apparatus thereof are provided to extend coverage as increasing capacity of a control channel. CONSTITUTION: A base station(10) includes a macro base station, a micro base station and a relay. The macro base station manages a cell of wide range, and the micro base station manages a small network cell. The base station transmits data to terminals(20a-20d) included in a communication coverage area directly or through the relay. The base station transmits data through the relay to a terminal which is unable to be communicated directly as being located out of the communication coverage area. A terminal(20) includes a mobile phone, a portable computer having mobile communication function, a PDA having mobile communication function and a portable wireless communication device or system in a random type. The relay or the terminal transmits a signal to the base station through an uplink channel, and transmits the signal to the relay or the terminal through a downlink channel.</p> |
