ABSTRACT:
An apparatus and method for transmitting a control signal using a symbol or bit pattern of an existing pilot channel, instead of using the time multiplexing method in the separate code channel or the existing physical channel, and reducing an error rate while a reception side detects the control signal are provided. For that purpose, a transmission side allocates transmission power corresponding to a pilot pattern determined according to the control information. A corresponding reception side detects control information based on a pilot pattern of pilot bits inserted in a dedicated physical channel (DPCH) and generates transmit power control (TPC) bits referring to a target reception power which is set based on the control information.
