Method and system for providing channel assignment information used to support uplink and downlink channels
First Claim
1. A method for utilizing channel control information associated with enhanced uplink (EU) transmission, implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving information via radio resource control (RRC) signaling;
receiving downlink (DL) control information for at least EU transmission in at least one time slot, wherein the DL control information is at least a first type or a second type, and wherein the DL control information of the first type and the DL control information of the second type are received via a same channel, and wherein the DL control information is masked with a forty bit WTRU specific code sequence;
determining whether the DL control information is intended for the WTRU based at least upon the forty bit WTRU specific code sequence received in the at least one time slot and the information received via RRC signaling;
determining that the DL control information is the first type or the second type based upon the forty bit WTRU specific code sequence and the information received via RRC signaling; and
utilizing the DL control information of the first type or the second type for at least EU transmission on a condition that the DL control information is intended for the WTRU.

Abstract
A method and wireless transmit/receive unit (WTRU) for utilizing channel control information associated with enhanced uplink (EU) transmission is disclosed. The WTRU receives information via radio resource control (RRC) signaling and receives downlink (DL) control information for at least EU transmission. The WTRU determines whether the DL control information is intended for the WTRU based at least upon a first forty bit specific code sequence and a second forty bit specific code sequence received in at least one time slot and determines whether the DL control information is the first type or the second type. The WTRU utilizes the DL control information of the first type or the second type for at least EU transmission on a condition that the DL control information is intended for the WTRU.
