Resource Allocation Frame With Contiguous User Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for higher WLAN wireless communication rates, particularly with the introduction of OFDMA technology in 802.11ax, poses a challenge in effectively allocating communication resources to improve communication robustness across different locations.
Innovation Solution
A resource allocation method and apparatus that generates a frame with multiple user information fields, each containing a user identifier subfield, to allocate resources to the same user across different locations, using HE MU PPDU or trigger frames, with indication information to ensure data transmission robustness by utilizing contiguous user information fields and standardized subfields for resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple resources are allocated to the same user across different locations, then data transmission robustness is improved, but frame structure complexity increases
Solution Approach 1:
The frame structure is segmented into multiple user information fields, each capable of containing user identifier subfields. This segmentation allows the same user to be identified across multiple fields, enabling resource allocation at different locations while maintaining a modular and manageable frame structure.
Solution Approach 2:
The user information fields are designed with universal structure that can serve multiple functions: identifying different users or the same user at different locations. The user identifier subfield within each user information field acts as a universal key that can reference any user, enabling flexible resource allocation without increasing overall frame complexity.
2Loss of time
If user information fields are placed contiguously, then user can end reading faster and prepare for data transmission sooner, but resource allocation flexibility is reduced
Solution Approach 1:
The frame structure incorporates dynamic elements where user information fields can be arranged contiguously for fast reading, yet the internal structure of each field remains flexible. The user identifier subfield can dynamically reference different users or the same user at different locations, maintaining adaptability while benefiting from contiguous placement for reduced reading time.
Data Source
AI summary
A resource allocation method includes generating a first frame and sending the first frame. The first frame includes a plurality of user information fields. Each user information field of the plurality of user information fields includes one user identifier subfield and is used to allocate a resource to a user identified by the user identifier subfield. Two or more user information fields in the plurality of user information fields have corresponding values of corresponding user identifier subfields that are the same.
