Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peer-to-peer (P2P) wireless networks face challenges in efficiently managing resources and responding to ranging requests, especially when multiple devices with different protocols, including legacy and newer ones, share the same resources, leading to bandwidth and response time issues.
Innovation Solution
The implementation of methods and apparatuses that allow wireless devices to synchronize timing and automatically respond to ranging requests within P2P networks, using IEEE 802.11 protocols such as 802.11ax/mc/ay, by configuring MAC layers to manage time slots and determine whether to auto-respond to ranging requests based on pre-set conditions, ensuring efficient resource allocation and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices with different protocols share the same resources in a P2P network, then device compatibility and network versatility are improved, but bandwidth efficiency and response time deteriorate
Solution Approach 1:
The patent segments the P2P network into protocol-specific virtual channels or logical groups, allowing devices with different protocols to communicate within their own segments while sharing the physical medium. This segmentation prevents protocol conflicts and maintains bandwidth efficiency for each protocol type while preserving overall network versatility.
Solution Approach 2:
The patent introduces a protocol translation layer or intermediary device that mediates between different protocol types. This intermediary converts messages between legacy and newer protocols, enabling device compatibility without requiring all devices to use the same protocol, thereby maintaining bandwidth efficiency by avoiding repeated transmissions.
2Measurement precision
If manual response configuration is used for ranging requests in P2P networks, then response accuracy and measurement precision are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements self-service mechanisms where devices automatically configure their ranging response parameters based on pre-stored profiles or adaptive algorithms. The device autonomously determines optimal response settings without requiring manual user configuration, thereby maintaining measurement precision while reducing operational complexity.
Solution Approach 2:
The patent employs preliminary configuration of ranging parameters through pre-stored profiles that contain optimized settings for different scenarios. When a ranging request is received, the device automatically selects and applies the appropriate pre-configured profile, ensuring accurate responses without requiring real-time manual configuration or complex user input.
3Productivity
If automatic response mechanisms are implemented for ranging requests, then response time and network productivity are improved, but measurement precision and control flexibility deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the automatic response system continuously monitors ranging measurement results and adjusts its behavior accordingly. When precision requirements are detected, the system automatically switches to a more controlled response mode, thereby maintaining both fast response times and high measurement precision through adaptive feedback control.
Solution Approach 2:
The patent makes the response mechanism dynamic by allowing automatic and manual modes to switch based on operational conditions. The system can operate in automatic mode for fast responses under normal conditions, but transitions to manual or semi-automatic modes when high precision is required, providing both speed and accuracy as needed.
4Adaptability or versatility
If legacy protocol compatibility is maintained alongside newer protocols, then device adaptability is improved, but resource allocation efficiency and network performance deteriorate
Solution Approach 1:
The patent implements a universal message format and resource allocation mechanism that can accommodate both legacy and newer protocols through a common interface. This multi-functional approach allows the network to efficiently allocate resources to devices using different protocols without requiring separate management systems, thereby maintaining both protocol compatibility and resource allocation efficiency.

AI summary
The application layer of a first wireless device may be configured to receive a ranging request indication from a MAC layer of the first wireless device, determine whether the MAC layer should respond to the ranging request, and send a ranging response to the MAC layer with an indication of whether to respond to the ranging request. The MAC layer may be configured to decode a ranging set-up request from a second wireless device, where the ranging set-up request comprises time slots. If an auto-response is set to false, send a ranging request indication to the application layer and receive from the application layer a ranging response, and if the auto-response is set to true or the ranging response indicates the MAC layer should respond to the ranging set-up request, select a time slot, and encode a ranging response with an indication of the selected time slot.
