First Claim
1. 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.

Abstract
A method and wireless communication system for providing channel assignment information used to support an uplink (UL) channel and a downlink (DL) channel. The system includes at least one Node-B and at least one wireless transmit/receive unit (WTRU). The WTRU communicates with the Node-B via a common control channel, the UL channel and the DL channel. The WTRU receives a message from the Node-B via the common control channel. The message includes an indication of whether the message is intended for assigning radio resources to the UL channel or the DL channel. The WTRU determines whether the message is intended for the WTRU and, if so, the WTRU determines whether the message is for assigning radio resources to the UL channel or the DL channel. The WTRU takes an appropriate action based on whether the message is for assigning radio resources to the UL channel or the DL channel.
