FMS Transmission Parameter Signaling for Multi-Link Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently managing power consumption and data transmission in stations operating in a dormant state, particularly in scenarios where multiple transmission links are involved, leading to suboptimal power saving and data acquisition efficiency.
Innovation Solution
The implementation of a flexible multicast service (FMS) descriptor element in wireless communication methods and apparatuses that includes transmission parameters for multiple transmission links, allowing stations to efficiently manage power consumption and data acquisition by providing extended power-saving states and accelerated data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If stations wake up frequently to check for downlink data on multiple transmission links, then data acquisition timeliness is improved, but power consumption increases
Solution Approach 1:
The access point performs preliminary action by sending a indication frame in advance that contains transmission parameter information for multiple transmission links. This allows the station to know ahead of time which links will carry downlink data, so the station can wake up only when needed and check only the relevant links, avoiding frequent wake-ups and unnecessary link checking.
Solution Approach 2:
The indication frame acts as an intermediary that carries transmission parameter information from the access point to the station. This intermediary provides the station with advance knowledge about downlink data transmission without requiring the station to actively monitor all links continuously, thus reducing power consumption while maintaining timely data acquisition.
2Reliability
If stations monitor all transmission links continuously, then data transmission reliability is improved, but power saving capability deteriorates
Solution Approach 1:
The access point sends transmission parameter information in advance through the indication frame, telling the station which specific transmission links will carry downlink data. This preliminary information allows the station to monitor only the necessary links at appropriate times, ensuring reliable data reception without the need for continuous monitoring of all links.
Solution Approach 2:
Instead of requiring the station to monitor all transmission links continuously (excessive action), the indication frame enables the station to monitor only the specific links that will actually carry downlink data (partial action). This reduces power consumption while maintaining sufficient reliability for data transmission.
3Measurement precision
If transmission parameters are sent separately on each transmission link, then link-specific information accuracy is improved, but signaling overhead increases
Solution Approach 1:
The indication frame merges the transmission parameter information for multiple transmission links into a single frame sent on one link. Instead of sending separate indication frames on each transmission link, all the link-specific transmission parameters are consolidated into one frame, reducing signaling overhead while maintaining accurate link-specific information through dedicated fields for each link.
Solution Approach 2:
The indication frame serves multiple functions simultaneously: it carries transmission parameter information for multiple different transmission links within a single frame structure. This multi-functionality allows the frame to provide link-specific accurate information while reducing the total number of frames and signaling overhead.
