1Productivity

If monostatic sensing procedures are implemented over mmWave band using coordinated availability windows, then data transmission rates are enhanced, but device complexity increases due to coordinated scheduling across multiple channels

Engineering Contradiction:

Improvedata transmission rateVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the mmWave communication process into distinct availability windows for sensing operations. Each availability window represents a scheduled time slot where sensing can occur without interfering with regular data transmission, thereby enabling high data rates while managing device complexity through structured time division

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements periodic sensing opportunities through regularly scheduled availability windows. These periodic time slots allow the system to maintain high overall data transmission rates while consistently providing sensing capabilities, balancing productivity enhancement with manageable device complexity through predictable periodic operation

Inventive Principle:

Principle #19Periodic action

Solution Approach 1:

The patent ensures continuous sensing capability by establishing periodic availability windows that repeatedly occur throughout operation. This continuous periodic action maintains reliable sensing functionality without requiring complex ad-hoc scheduling, as the repeated pattern allows devices to anticipate and prepare for sensing opportunities

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent establishes availability windows in advance through coordinated scheduling, allowing devices to prepare for sensing operations before they occur. This preliminary arrangement of sensing opportunities in predetermined time slots enhances communication reliability while avoiding the complexity of real-time dynamic scheduling

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic availability windows that can be adjusted in duration and frequency based on sensing requirements and channel conditions. This dynamic adaptation allows the system to optimize sensing capabilities for different scenarios while minimizing time loss by adjusting the timing and length of availability windows to match actual needs rather than using fixed schedules

Inventive Principle:

Principle #15Dynamics

AI summary

For example, an apparatus may include logic and circuitry configured to cause a sensing initiator station (STA) to transmit one or more timeslot-scheduling frames over a sub 10 Gigahertz (GHz) (sub-10GHz) wireless communication frequency band to schedule one or more timeslots of a coordinated monostatic millimeterWave (mmWave) sensing measurement exchange for a plurality of sensing responder STAs; to transmit a trigger frame over an mmWave wireless communication frequency band during a timeslot of the one or more timeslots; and to process a frame from a sensing responder STA to participate in a monostatic sounding during the timeslot, the frame from the sensing responder STA received over the mmWave wireless communication frequency band during the timeslot.
