WTRU Selective Downlink EU Signaling Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems require continuous reception of downlink enhanced uplink signaling channels, leading to increased processing requirements and the probability of misinterpretation, especially in scenarios where these channels are not constantly needed.
Innovation Solution
A method and apparatus that allow the wireless transmit/receive unit (WTRU) to selectively enable and disable the reception of downlink enhanced uplink signaling channels based on established standard procedures, reducing unnecessary processing and potential misinterpretation by coordinating and consolidating reception requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the WTRU continuously enables reception of DL EU signaling channels, then the WTRU can receive all necessary channel allocation and feedback information, but the processing requirements and power consumption increase
Solution Approach 1:
The patent implements periodic monitoring of DL EU signaling channels instead of continuous reception. The WTRU activates reception only at specific time intervals when channel allocation or feedback information is expected, thereby reducing power consumption while maintaining reliable communication through timely information reception.
2Reliability
If the WTRU continuously monitors DL EU signaling channels, then all signaling information is captured, but processing requirements and error probability increase
Solution Approach 1:
The patent applies periodic monitoring where the WTRU activates signaling channel reception only at predetermined intervals when channel allocation or feedback is anticipated. This reduces processing complexity by limiting monitoring to necessary time windows while maintaining signaling reception reliability through coordinated activation with transmission events.
Solution Approach 2:
The WTRU autonomously determines when to activate DL EU signaling channel reception based on its own transmission schedule and expected feedback timing. The device self-manages its monitoring requirements without continuous external control, reducing processing overhead while ensuring reliable reception at critical moments.
3Loss of information
If DL EU signaling channel reception is continuously enabled, then complete information is received, but unnecessary processing occurs when channels are not needed
Solution Approach 1:
The patent implements periodic activation of DL EU signaling channel reception aligned with transmission events. The WTRU monitors channels only when channel allocation or feedback information is expected to be transmitted, ensuring complete information reception at these critical moments while avoiding unnecessary processing during periods when no signaling is anticipated.

AI summary
In a wireless communication system including a wireless transmit/receive unit (WTRU) and at least one Node-B, a method and apparatus is used to selectively enable reception of at least one downlink (DL) enhanced uplink (EU) signaling channel established between the WTRU and the Node-B(s). During the operation of an enhanced dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the Node-B(s) only when it is necessary, based on the WTRU's knowledge of at least one established standard procedure. The WTRU coordinates and consolidates DL signaling channel reception requirements of a plurality of channel allocation and/or data transmission procedures carried out by the WTRU in accordance with the established standard procedure. The WTRU determines whether to enable reception of at least one specific DL signaling channel based on the consolidated DL signaling channel reception requirements.
