Multi-Link Device Power State Management via TID Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless device communication systems lack the ability to establish simultaneous multiple links through a single access point and do not indicate initial power states of multiple connections after a traffic identifier (TID) mapping function, limiting their functionality in managing link states and power management.
Innovation Solution
The implementation of a multi-link device (MLD) system that enables multiple links by a two-way handshake, allowing for bidirectional link setup, TID mapping, and defining initial power states based on link usage, with the system setting the initial power management mode to active or power save mode depending on the link state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wireless communication system establishes a single link through an access point, then the system maintains simple device architecture and operation, but the system cannot establish simultaneous multiple links, limiting functionality and adaptability
Solution Approach 1:
The patent segments the wireless communication system into multiple independent links, each with its own traffic identifier (TID) mapping function. Instead of a single monolithic connection, the system divides communication into multiple parallel links that can be independently managed, enabling simultaneous multi-link operation while maintaining manageable complexity through modular architecture
Solution Approach 2:
The patent implements a universal multi-link device (MLD) architecture that can simultaneously handle multiple links with different characteristics and requirements. The MLD framework provides a unified management mechanism that works across diverse link configurations, making the system adaptable to various scenarios while maintaining a single coherent device structure
2Use of energy by moving object
If the system does not indicate initial power states after TID mapping, then the device complexity is reduced, but the system lacks the ability to optimize power management for multiple connections
Solution Approach 1:
The patent implements a feedback mechanism where the system indicates initial power states after TID mapping function execution. This feedback provides information about the current power state of each link, enabling the device to make informed decisions about power management. The feedback loop allows the system to adjust power consumption based on actual link states and traffic requirements
Solution Approach 2:
The patent performs preliminary power state indication immediately after the TID mapping function, establishing the initial power state before actual data transmission begins. This preliminary action allows the device to pre-configure power management parameters and anticipate energy requirements, enabling more efficient power optimization throughout the communication session

AI summary
This disclosure describes systems, methods, and devices related to initial power state. A device may identify a request frame received from a non-AP MLD on a first link of a plurality of links, wherein the non-AP MLD comprises a plurality of station devices (STAs), and wherein the first link is associated with a first STA of the plurality of STAs. The device may cause to send a response frame to the non-AP MLD on the first link to establish the plurality of links between the device and the non-AP MLD. The device may determine, based on the request frame, a power save mode associated with each of the STAs of the non-AP MLD. The device may communicate with the non-AP MLD based on the power save mode.
