On-Demand Antenna Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antenna feedback schemes in wireless communication systems unnecessarily waste system resources and bandwidth by continuously transmitting feedback, even when no data is being received.
Innovation Solution
Implementing an on-demand antenna feedback mechanism where feedback is transmitted only when a receiving device is scheduled to receive data, using notifications to initiate feedback from the receiving device to the transmitting device, thereby conserving bandwidth and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna feedback is transmitted continuously regardless of data reception status, then the transmitting device can maintain updated antenna patterns, but system resources and bandwidth are wasted
Solution Approach 1:
The patent implements periodic action by having the receiving device transmit antenna feedback only at specific intervals when data is actually being received, rather than continuously. The feedback transmission is triggered by data reception events, creating a periodic rather than continuous feedback mechanism that conserves bandwidth while maintaining antenna pattern accuracy when needed.
Solution Approach 2:
The system uses the data reception process itself to trigger the feedback transmission. When the receiving device receives data, it automatically generates and transmits antenna feedback without requiring separate continuous feedback transmissions. This self-service approach ensures feedback is provided when necessary while avoiding unnecessary transmissions during idle periods.
2Productivity
If antenna feedback is transmitted continuously, then the base station can maintain optimal antenna patterns, but system resources are unnecessarily consumed
Solution Approach 1:
The patent reduces feedback transmission volume by implementing periodic action where feedback is sent only when data reception occurs. This triggers feedback transmission at appropriate intervals rather than continuously, maintaining data transmission efficiency through timely feedback while significantly reducing the total quantity of feedback transmissions.
Solution Approach 2:
The patent extracts the essential feedback transmission moments from the continuous feedback stream, keeping only those feedback transmissions that occur when data is being received. This extraction approach removes unnecessary feedback transmissions while preserving the critical feedback needed for optimal antenna pattern maintenance during actual data transfer.
3Loss of energy
If antenna feedback is sent only on demand, then bandwidth is conserved, but feedback may not be available when needed
Solution Approach 1:
The patent applies preliminary action by having the receiving device generate antenna feedback immediately when data is received, ensuring feedback is prepared and transmitted without delay. The feedback generation is triggered in advance of any potential antenna pattern adjustments needed, ensuring timely availability while maintaining bandwidth conservation through on-demand transmission.
Solution Approach 2:
The system implements a feedback mechanism where the receiving device monitors data reception and automatically triggers feedback transmission when data is received. This closed-loop feedback ensures that antenna pattern information is updated timely based on actual transmission conditions, balancing bandwidth conservation with feedback availability.

AI summary
A feedback method in which a notification is received that a transmitting device has scheduled a transmission of data to the receiving device. Antenna feedback is generated in response to receipt of the notification. The antenna feedback is sent to the transmitting device. A mobile device includes a wireless network interface and a processor configured to receive a notification that a transmitting device has scheduled transmission of data to the mobile device, to generate antenna feedback in response to receipt of the notification, and to send the antenna feedback over the interface to the transmitting device.
