Base Station Control Signaling for Multi-MAP Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coordinated communication in radio LANs, such as those discussed in IEEE 802.11be, lack efficient methods for controlling various types of coordinated communication, leading to suboptimal signaling efficiency.
Innovation Solution
A base station with control circuitry determines the format of a control signal based on the type of coordinated communication and transmits it to another base station, using a MAP Trigger frame to integrate and efficiently control multiple MAP types, including C-SR, C-OFDMA, JT, and CBF, by including specific parameters that depend or do not depend on the MAP type.

Engineering Contradiction Analysis
1Device complexity
If a unified control signal format is used for all coordinated communication types, then device complexity is reduced, but signaling efficiency deteriorates
Solution Approach 1:
The control signal format is made dynamic by selecting different formats based on the MAP type. The base station dynamically chooses between first format (for joint transmission) and second format (for other MAP types) according to the coordination type required, optimizing signaling efficiency without permanently increasing system complexity
Solution Approach 2:
The invention changes the format parameters of the control signal based on the MAP type. By modifying the signal format parameters (such as included fields and structure) according to the specific coordinated communication type, the system achieves optimized signaling efficiency for each scenario while maintaining manageable device complexity through standardized format selection
2Productivity
If multiple separate control signal formats are used for different coordinated communication types, then signaling efficiency is improved, but device complexity increases
Solution Approach 1:
The invention creates a universal control signal framework that can handle multiple MAP types. By designing format selection mechanisms that work across different coordinated communication types (joint transmission, coordinated beamforming, coordinated spatial reuse, coordinated OFDMA), the system achieves signaling efficiency optimization without requiring completely separate control mechanisms for each type
Solution Approach 2:
Rather than maintaining multiple static format definitions, the system uses dynamic format selection based on the operational MAP type. This reduces device complexity by implementing a single flexible formatting mechanism that adapts to different communication scenarios, while still achieving the signaling efficiency benefits of type-specific optimization
