Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the current IEEE 802.11ad-2012 grant frame format is used, then compatibility with existing standards is maintained, but the frame is not applicable, efficient, and/or sufficient for various scenarios and use cases in millimeter-wave networks
Solution Approach 1:
The patent applies dynamics by making the grant frame structure flexible and adaptable rather than fixed. The frame includes configurable fields such as Time Allocation Information that can be dynamically adjusted based on different scenarios and use cases, allowing the same frame structure to serve multiple purposes in millimeter-wave networks while maintaining compatibility with IEEE 802.11ad-2012
Solution Approach 2:
The patent implements universality by designing a grant frame that can handle multiple types of allocations (contended-based access, scheduled access, beamforming) within a single unified structure. The frame includes versatile fields that can be configured for different access types and scenarios, making it universally applicable across various millimeter-wave network use cases
2Productivity
If the current grant frame fields and subfields are used, then standard compliance is achieved, but efficiency and sufficiency for various scenarios are compromised
Solution Approach 1:
The patent applies segmentation by dividing the grant frame into distinct functional fields and subfields (Time Allocation Information, Frequency Allocation Information, Beamforming Information, etc.). Each field can be independently configured and optimized for specific scenarios, allowing efficient communication while covering diverse use cases through modular field design
3Productivity
If dynamic allocation of channel time is implemented, then communication efficiency is enhanced, but the complexity of time management increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring time allocation parameters and allocation rules in the grant frame before actual channel access occurs. The Time Allocation Information field contains pre-calculated timing parameters that stations can use directly, reducing real-time management complexity while enabling efficient dynamic channel utilization

AI summary
Some demonstrative embodiments include apparatuses, devices, systems and methods of dynamic allocation using a grant frame. For example, a wireless station may be able to generate a grant frame including a duration field and a Dynamic Allocation Info field, the Dynamic Allocation Info field including an allocation duration subfield and an access mode subfield, the access mode subfield to indicate an access mode of an allocation according to the grant frame; and to transmit the grant frame.
