Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication terminals with enhanced multi-link single radio (eMLSR) mode are limited by the performance of their simple PHY units, which restrict bandwidth to 20 MHz or 40 MHz, preventing broadband uplink transmission.
Innovation Solution
A wireless communication terminal with one PHY unit and multiple simple PHY units performs switching processing from the simple PHY unit to the PHY unit during channel scanning for uplink transmission, enabling broadband communication while minimizing power consumption and avoiding conflicts with downlink transmission.

Engineering Contradiction Analysis
1Productivity
If the STA uses a simple PHY unit for channel scanning in eMLSR mode, then power consumption is reduced and device complexity is lowered, but bandwidth is limited to 20 MHz or 40 MHz preventing broadband uplink transmission
Solution Approach 1:
The patent implements dynamic switching between simple PHY unit and full PHY unit based on operational requirements. During channel scanning, the simple PHY unit is used to save power and reduce complexity. When uplink transmission is required, the system switches to the full PHY unit to enable broadband operation. This dynamic adaptation allows the system to optimize between power consumption/complexity and bandwidth based on current operational needs.
Solution Approach 2:
The patent changes the operational parameters of the PHY unit by switching between different modes (simple PHY vs. full PHY) depending on the task requirements. For channel scanning operations, the system operates in simple PHY mode with limited bandwidth. For uplink transmission operations, the system switches to full PHY mode with extended bandwidth capabilities, thereby changing the operational parameters to match the required performance level.
2Productivity
If the STA switches from simple PHY unit to PHY unit during channel scanning, then broadband uplink transmission is enabled, but switching time and potential conflicts with downlink transmission increase
Solution Approach 1:
The patent performs the PHY unit switching action in advance during the channel scanning period, before actual uplink transmission is required. By completing the switching operation during the scanning phase when the system is already actively using the radio interface, the patent minimizes additional switching time and ensures the full PHY unit is ready for broadband transmission without delaying the actual data transfer.
Solution Approach 2:
The patent implements a control mechanism that monitors the scanning state and transmission requirements to determine when switching from simple PHY to full PHY is appropriate. This feedback-based control ensures switching occurs at optimal moments, minimizing interference with downlink transmissions and reducing unnecessary switching operations that would waste time and increase complexity.
