Mobile Station Early Termination of Wireless Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices, especially mobile stations, face significant power consumption issues due to receiving non-relevant wireless transmissions in congested environments, which reduces battery life and consumer preference.
Innovation Solution
Implementing a method for early termination of wireless reception in IEEE 802.11 systems by determining if a transmission is intended for the mobile station based on the destination address in the MAC header, allowing the device to enter a low power mode before completion of the transmission, with the duration of the low power mode based on the transmission duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the mobile station continues receiving the wireless transmission until completion, then the reception is complete and reliable, but the power consumption increases unnecessarily
Solution Approach 1:
The mobile station performs preliminary checking of the destination address in the MAC header before completing the full reception of the transmission. By early termination based on address mismatch detection, the device avoids unnecessary power consumption while maintaining reliable operation for intended transmissions.
2Duration of action of moving object
If the mobile station enters low power mode early, then the battery life is extended, but the device may miss relevant transmission data
Solution Approach 1:
The mobile station performs preliminary verification of the destination address from the MAC header before entering low power mode. This preliminary action ensures that relevant transmissions are identified and fully received, while allowing early termination for non-relevant transmissions, thus extending battery life without losing important data.
Solution Approach 2:
The mobile station uses feedback from the destination address checking mechanism to dynamically control reception behavior. When the destination address matches, the device continues receiving; when it doesn't match, the device terminates early and enters low power mode, optimizing battery life based on real-time transmission relevance assessment.
3Ease of operation
If the mobile station checks the destination address from the MAC header, then the early termination is enabled, but the device complexity increases
Solution Approach 1:
The mobile station extracts only the destination address information from the MAC header for comparison purposes, rather than processing the entire transmission. This extraction approach enables early termination functionality while minimizing the processing complexity and computational overhead required.

AI summary
Performing early termination of reception by a mobile station. The mobile station may receive a wireless transmission. The wireless transmission may include a physical layer (PHY) header, a media access control (MAC) header, and data. The mobile station may determine a duration and a destination address from the MAC header. The mobile station may determine if the wireless transmission is intended for the mobile station using the destination address. In response to determining that the wireless transmission is not intended for the mobile station, the mobile station may enter a low power mode prior to completion of the wireless transmission. The length of time of the low power mode may be based on the duration of the first wireless transmission.
