Solution Overview

Problem

Existing communication technologies face challenges in enabling simultaneous communication between an access point (AP) and a non-AP station (STA) while minimizing interference with peer-to-peer (P2P) links in wireless networks.

Innovation Solution

The implementation of an overlay P2P trial phase to evaluate interference levels and schedule subsequent communication phases, allowing the AP and P2P STAs to communicate simultaneously by configuring channel access and transmission rules to mitigate interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If overlay P2P communication is implemented to enable simultaneous communication between AP link and P2P links, then productivity is improved, but interference between links increases

Engineering Contradiction:
Improvesimultaneous communication capabilityVSAvoidinterference between links
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent implements a trial phase before actual overlay P2P communication where the AP transmits trial information and receives link measurement information from STAs to evaluate channel conditions and interference levels in advance. Based on these preliminary measurements, the AP determines whether to schedule overlay communication and configures appropriate parameters, thereby preventing harmful interference before it occurs while enabling simultaneous communication when conditions permit.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If link measurement and trial phase are implemented to evaluate interference, then reliability is improved, but loss of time increases

Engineering Contradiction:
Improveinterference evaluation accuracyVSAvoidtrial phase duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a trial phase with partial action by transmitting trial information and collecting link measurement information from STAs only when needed for overlay P2P communication setup. The trial phase is not continuously executed but triggered selectively, performing measurements to the extent necessary to evaluate interference conditions and make scheduling decisions, thereby balancing reliability improvement with time efficiency.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A first communication device that is configured to operate as access point (AP) and to communicate with a second communication device that is configured to operate as station (STA) comprises circuitry configured to: transmit trial information to the second communication device and at least two third communication devices, the trial information requesting the second communication device and at least two third communication devices to perform link measurement and transmit link measurement information; perform link measurement and/or receive link measurement information from the second communication device and/or one or more third communication devices; and schedule, under consideration of the measured link and/or the received link measurement information, one or more overlay communication phases in which two third communication devices communicate with each other simultaneously with the communication between the first and second communication devices.
