1Productivity
If multiple user terminals communicate concurrently with a single access point using MIMO technology, then data throughput is improved, but difficulty of detecting and measuring control field information increases
Solution Approach 1:
The control field is segmented into multiple subfields, each carrying specific information. The first subfield indicates the type of control field, while the second subfield contains additional control information. This segmentation allows receivers to efficiently parse and interpret control information in multi-user MIMO environments without increasing overall detection difficulty.
Solution Approach 2:
An indicator field acts as an intermediary element that signals the presence and type of control field information. This intermediary mechanism enables user terminals to quickly identify whether control field information is present and what type it is, facilitating efficient processing in concurrent transmission scenarios.
2Reliability
If control field information is included in data units, then reliability of data transmission is improved, but device complexity increases
Solution Approach 1:
The control field is divided into structured subfields with specific functions. The first subfield indicates control field type, and the second subfield contains specific control parameters. This structured segmentation enables systematic processing that improves reliability while managing complexity through organized information representation.
Solution Approach 2:
The control field information is prepared and embedded in data units before transmission. By pre-structuring the control information with clear indicators and subfields, the receiving end can process this information more efficiently without requiring complex real-time analysis, thus improving reliability while controlling processing complexity.
