Multi-AP Link Switching for EMLSR Terminal Wireless Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the IEEE 802.11be standard, terminals in enhanced multi-link single radio (EMLSR) mode lack the capability to independently control transmission and reception on multiple wireless links, limiting their use of the multi-AP function.
Innovation Solution
A terminal device with a sharing access point and multiple shared access points, equipped with a first wireless signal processing unit and a management unit, allocates different identifiers to radio units and manages connections to enable independent control of wireless links using a second identifier, allowing multi-AP functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal uses EMLSR mode with multiple antennas to establish multiple wireless links, then the terminal can connect to multiple access points, but the terminal cannot independently control transmission and reception in each wireless link due to having only one access control function and one signal processing function
Solution Approach 1:
The patent divides the single signal processing function into multiple independent signal processing units (first wireless signal processing unit, second wireless signal processing unit, etc.), each capable of independently processing signals for different wireless links. This segmentation enables independent control of transmission and reception on each link while maintaining EMLSR mode operation.
2Adaptability or versatility
If a terminal has only one access control function and one signal processing function, then the device complexity is reduced, but the terminal cannot use the multi-AP function effectively
Solution Approach 1:
The patent introduces a management unit that operates at a higher organizational level, dynamically allocating and managing multiple signal processing units across different wireless links. This dimensional change allows the system to achieve multi-AP functionality without permanently increasing device complexity, as the additional units are activated and managed on-demand rather than being permanently instantiated.

AI summary
A terminal apparatus is a terminal apparatus in a communication system including a sharing access point, a plurality of shared access points, and a terminal apparatus. The apparatus includes a first wireless signal processing unit and a management unit. The first wireless signal processing unit processes a wireless signal for transmitting and receiving the wireless signal using each of a plurality of radio units. The management unit manages a connection destination of the first wireless signal processing unit. The first wireless signal processing unit is allocated with a plurality of different first identifiers respectively corresponding to the plurality of radio units. The management unit switches the first identifier according to a second identifier allocated to a second wireless signal processing unit that transmits and receives the wireless signal to and from the first wireless signal processing unit among one or more second wireless signal processing units of each of the shared access points, and controls a connection destination of the radio unit.
