Patent ID: 7200405

Claim:
In a wireless communication system including at least one Node-B and at least one wireless transmit/receive unit (WTRU), a method for selectively assigning radio resources for one of an enhanced uplink (EU) channel and a high speed downlink packet access (HSDPA) channel via common channel assignment information, the common channel assignment information being transmitted from the Node-B to the WTRU via at least one control channel, the method comprising: (a) the WTRU receiving a message from the Node-B via the at least one control channel, the message including the common channel assignment information and an indication of whether the common channel assignment information is intended for assigning radio resources to the EU channel or the HSDPA channel; (b) the WTRU determining whether the message is intended for the WTRU; (c) the WTRU detecting the indication; and (d) the WTRU taking an appropriate action based on the detected indication at step (c), whereby radio resources are selectively assigned for one of the HSDPA channel and the EU channel via the common channel assignment information.
