WUR Discovery Element Channel Decision for Roaming Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless LAN communication systems adhering to the IEEE802.11ba standard, there is a lack of efficient methods for determining the PCR channel used for communication with a second AP during roaming, leading to increased power consumption and connection time due to the need for channel searching.
Innovation Solution
A communication apparatus and method that includes a reception unit for receiving radio frames, an acquisition unit for acquiring WUR Discovery element information, and a decision unit for determining the WUR channel to wait for a WUR Discovery frame, based on the received information, thereby optimizing channel selection for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the STA searches for and decides the PCR channel used for communication with the second AP during roaming, then the connection reliability is improved, but the power consumption increases and the connection time is extended
Solution Approach 1:
The patent applies preliminary action by having the STA acquire WUR Discovery element information in advance during the roaming process. This information contains pre-configured WUR channel settings that the STA can use immediately, eliminating the need for time-consuming channel searches and reducing power consumption while maintaining connection reliability

AI summary
A communication apparatus receives a radio frame complying with an IEEE802.11 series standard, acquires information of a WUR (Wake-up Radio) Discovery element included in the received frame, and decides, based on the information of the WUR Discovery element, a WUR channel used to wait for a WUR Discovery frame.
