The present invention relates to a common channel generating method and device in a downlink. Receiving performance by the mobile station is improved by efficiently allocating the resource and generating the common channel in the downlink. Also, transmission diversity applied to the number of transmit antennas of the base station and the common channel can be easily detected, thereby acquiring the mobile station's initial process.

Method and apparatus for creating common physical channel

Provided are a method and apparatus for transmitting control information and packet data. The method includes generating control channels which transmit the control information; generating control indication channel which indicates whether the control channels are transmitted or not; generating data channels in order to transmit the packet data based on the control information; multiplexing the control channels, the control indication channels, and the data channels; and transmitting the control channels, the control indication channels, and the data channels. According to the present invention, when control information and packet data are transmitted in downlink, by transmitting additional information indicating whether control channels are transmitted or not, resources not actually allocated to control channels can be allocated to data channel and the mobile station can receive data channel using the control indication information.
