Solution Overview

Problem

Existing wireless communication systems face challenges in maintaining power-saving states of Access Points (APs) due to disruptions from external factors, leading to increased energy consumption and inefficiencies, which are not adequately addressed by current multi-AP coordination schemes.

Innovation Solution

A method and system for establishing Multi-AP Coordination for AP Power Saving (MAPC) that involves a primary AP initiating negotiations with secondary APs based on trigger parameters, exchanging capability information, and generating an optimal Negotiated Power Saving Profile (NPP) to coordinate power-saving strategies among neighboring APs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If existing power-saving schemes are implemented, then energy consumption is reduced, but reliability of data communication deteriorates due to disruptions from external factors

Engineering Contradiction:

Improveenergy consumptionVSAvoidreliability of data communication

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent combines multiple APs into a coordinated group where they share power-saving states and channel access decisions. By merging their power management functions, the system achieves both energy savings and maintained reliability through collective coordination rather than individual operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a coordinator AP that acts as an intermediary between the external environment and sleeping APs. This coordinator receives and forwards frames during power-saving periods, mediating communication to maintain reliability while allowing other APs to remain in low-power states.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multi-AP coordination schemes are implemented, then channel usage is optimized, but device complexity increases due to negotiation protocols

Engineering Contradiction:

Improvechannel usage efficiencyVSAvoidcomplexity of coordination protocol

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary negotiation and capability exchange between APs before entering power-saving modes. By establishing coordination parameters, group memberships, and frame forwarding arrangements in advance, the system optimizes channel usage without requiring complex real-time negotiations during active communication.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for establishing coordination between a plurality of Access Points (APs) in a wireless network is provided. The method includes: initiating a Multi-AP Coordination for AP Power Saving (MAPC for AP PS) scheme, for the plurality of APs, based on one or more trigger parameters associated with a primary AP; receiving one or more broadcast frames from each of a plurality of secondary APs among the plurality of APs, the one or more broadcast frames comprise capability information corresponding to the secondary AP; identifying one or more neighbor APs from the plurality of secondary APs based on the received capability information; and performing one or more negotiation operations with the one or more identified neighbor APs to establish coordination between the primary AP and the one or more identified neighbor APs for coordinated data communication in the MAPC for AP PS scheme.
