Method and system for providing channel assignment information used to support uplink and downlink channels
First Claim
1. In a wireless communication system including a wireless transmit/receive unit (WTRU) and a Node-B, a method for selectively providing channel assignment information for an enhanced uplink (EU) channel and a high speed downlink packet access (HSDPA) channel, the method comprising:
- the Node-B transmitting channel assignment information to the WTRU for assigning radio resources for the WTRU;
the WTRU receiving the channel assignment information;
the WTRU determining whether the channel assignment information is for assigning the radio resources for the EU channel or the HSDPA channel; and
the WTRU utilizing the radio resources for one of the EU channel and the HSDPA channel.

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.

23. A Node-B for selectively providing channel assignment information to a wireless transmit/receive unit (WTRU) for an enhanced uplink (EU) channel and a high speed downlink packet access (HSDPA) channel, the Node-B comprising:
-
a scheduler for generating channel assignment information to assign a radio resource to the WTRU for one of the EU channel and the HSDPA channel; and
a transmitter for transmitting the channel assignment information to the WTRU, the channel assignment information enabling the WTRU to determine whether the channel assignment information is for assigning the radio resources for the EU channel or the HSDPA channel. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
