1. A method for utilizing channel assignment information for an uplink shared channel or a downlink shared channel, the method comprising:
- a wireless transmit/receive unit (WTRU) receiving downlink control information including downlink or uplink channel assignment information via a same physical downlink control channel, both downlink channel assignment information and uplink channel assignment information being received via the same physical downlink control channel;
the WTRU determining whether the downlink control information is intended for the WTRU based on WTRU identity (ID)-masked cyclic redundancy check (CRC) parity bits, and if so determining whether the channel assignment information is for assigning radio resources for the uplink shared channel or the downlink shared channel; and
the WTRU utilizing the radio resources for the uplink shared channel or the downlink shared 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.

16. A wireless transmit/receive unit (WTRU) for utilizing channel assignment information for an uplink shared channel or a downlink shared channel, the WTRU comprising:
-
a receiver configured to receive downlink control information including downlink or uplink channel assignment information via a same physical downlink control channel, both downlink channel assignment information and uplink channel assignment information being received via the same physical downlink control channel; and a controller configured to determine whether the downlink control information is intended for the WTRU based on WTRU identity (ID)-masked cyclic redundancy check (CRC) parity bits and to determine whether the channel assignment information is for assigning radio resources for the uplink shared channel or the downlink shared channel, and utilizing the radio resources for the uplink shared channel or the downlink shared channel. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A Node-B for selectively providing channel assignment information to a wireless transmit/receive unit (WTRU) for an uplink shared channel and or a downlink shared channel, the Node-B comprising:
-
a scheduler for generating configured to generate channel assignment information to assign radio resources to the WTRU for the uplink shared channel and or the downlink shared channel; and a transmitter for transmitting configured to transmit downlink control information including uplink or downlink channel assignment information and WTRU identity (ID)-masked cyclic redundancy check (CRC) parity bits to the WTRU via a same physical downlink control channel, both downlink channel assignment information and uplink channel assignment information being transmitted via the same physical downlink control channel, the downlink control information including an indication indicating whether the channel assignment information is for assigning the radio resources for the uplink shared channel or the downlink shared channel. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. A method for providing channel assignment information for an uplink shared channel or a downlink shared channel via a downlink control channel, the method comprising:
-
a Node B generating channel assignment information to assign radio resources to a wireless transmit/receive unit (WTRU) for the uplink shared channel or the downlink shared channel; and the Node B transmitting downlink control information including uplink or downlink channel assignment information and WTRU identity (ID)-masked cyclic redundancy check (CRC) parity bits to the WTRU via a same physical downlink control channel, both downlink channel assignment information and uplink channel assignment information being transmitted via the same physical downlink control channel, the downlink control information including an indication indicating whether the channel assignment information is for assigning the radio resources for the uplink shared channel or the downlink shared channel. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
