An apparatus and method for processing a paging in a WCDMA terminal realize a hardware device for checking whether or not there is a page by interpreting a PICH and an SCCPCH according to a DXR cycle. When a page is detected by this device, a digital base band unit (DBB) is turned on to analyze a PI (paging indicator) of the PICH and a MAC header of the SCCPCH. Therefore, there is no need to operate the DBB at every DXR cycle to check for a page, and thereby the processing loads of the DBB and power consumption of the WCDMA terminal can be reduced significantly.
