Solution Overview

Problem

The computational resource consumption for decoding resource unit allocation information in IEEE 802.11ax and IEEE 802.11be wireless communication systems is significant due to the complexity introduced by multi-resource unit mechanisms, particularly in the EHT standard, leading to inefficient use of processor resources.

Innovation Solution

A parsing mechanism that checks for consistency between consecutive data units' common fields, allowing the decoding of identical fields to be skipped, thereby reducing computational load and optimizing processor utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the station decodes the common field in every data unit to obtain resource allocation information, then the reliability of resource allocation information is ensured, but the computational resource consumption increases significantly

Engineering Contradiction:

Improvereliability of resource allocation informationVSAvoidcomputational resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by checking whether the common field in the current data unit is identical to the common field in the previous data unit before decoding. This pre-check allows the station to skip decoding the common field when no changes are detected, thereby reducing computational resource consumption while maintaining reliability through selective decoding only when necessary.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements the skipping principle by allowing the station to skip the decoding process of the common field when consistency with the previous data unit is confirmed. This selective skipping reduces unnecessary computational operations while ensuring that decoding occurs only when resource allocation information may have changed, thus balancing reliability and energy efficiency.

Inventive Principle:

Principle #21Skipping (Rushing through)

2Measurement precision

If the station decodes the common field in every data unit, then the accuracy of resource allocation information is ensured, but the processing time increases

Engineering Contradiction:

Improveaccuracy of resource allocation informationVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing a consistency check between the current and previous common fields before initiating decoding. This pre-check determines whether decoding is necessary, allowing the station to skip the time-consuming decoding process when no changes are detected, thereby reducing processing time while maintaining accuracy through selective decoding.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements skipping by allowing the station to bypass the decoding step when the common field remains unchanged compared to the previous data unit. This selective skipping significantly reduces processing time for repeated data units while ensuring accuracy is maintained for updated data through proper decoding.

Inventive Principle:

Principle #21Skipping (Rushing through)

3Quantity of substance

If the station performs comprehensive decoding of common fields, then the completeness of resource allocation information is ensured, but the processor performance-to-power ratio deteriorates

Engineering Contradiction:

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by checking for changes in the common field before decoding. This pre-check ensures that the station only decodes when necessary to maintain information completeness, avoiding unnecessary processing that would worsen the performance-to-power ratio while still ensuring complete and accurate resource allocation information when updates occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements skipping by allowing the station to skip decoding when the common field is unchanged, thereby reducing power consumption. This selective approach maintains information completeness for updated data while avoiding wasted processing power on repeated data, thus improving the processor performance-to-power ratio.

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

A method for a station to obtain resource unit allocation information, includes: receiving a first data unit, obtaining resource allocation information corresponding to the first data unit and obtaining a format description of a common field in a first signal field of the first data unit; receiving a second data unit, obtaining a format description of a common field in a first signal field of the second data unit; when the format descriptions of the common fields of the two data units are identical, comparing bits of the common fields between the two data units; and when the bits of the common fields of the two data units are identical, using the resource allocation information corresponding to the first data unit to parse a user-specific field of the first signal field of the second data unit, and accordingly configuring the station.
