Method and apparatus for selectively enabling reception of downlink signaling channels

In a wireless communication system including a wireless transmitter / receiver unit (WTRU) and at least one node B, there is a method and apparatus used selectively to connect at least one downlink (DL) enhanced uplink (EU) signaling channel established between WTRU and nodes-B. During operation of an improved dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the nodes-B only when needed, based on the WTRU knowledge of the at least one established standard procedure. The WTRU coordinates and consolidates the DL signaling channel receiving requirements into a plurality of channel allocation and / or data transmission procedures performed by the WTRU according to the established standard procedure.
