Solution Overview
Problem
Wireless communication devices face inefficiencies in managing data transfer between primary and secondary memories, leading to increased latency and power consumption due to inadequate coordination of data storage and configuration changes based on operational mode transitions.
Innovation Solution
Implementing device-coordinated dynamic configuration management techniques that involve switching data between primary and secondary configurations, such as memories or antenna settings, based on operational mode changes of the STA, to optimize memory usage and reduce latency.

Engineering Contradiction Analysis
1Loss of time
If data is stored in primary memory for quick access, then communication latency is reduced, but device complexity and power consumption increase due to continuous operation
Solution Approach 1:
The system dynamically transitions data between primary and secondary memory based on operational mode changes. When the device switches from active to power-saving mode, data is moved from primary to secondary memory, and vice versa. This dynamic adaptation allows the system to optimize the balance between fast access (low latency) and energy efficiency by adjusting memory usage according to actual operational needs
Solution Approach 2:
The system performs preliminary data transfer to secondary memory before entering power-saving mode, and pre-loads data from secondary to primary memory before transitioning to active mode. This preliminary action ensures that when the device needs to operate, the required data is already in the fast-access primary memory, minimizing latency upon wake-up while maintaining energy efficiency during idle periods
2Use of energy by moving object
If data is transferred between primary and secondary memory based on operational mode changes, then power consumption is reduced, but device complexity increases due to coordination requirements
Solution Approach 1:
The system implements self-service through automatic mode detection and trigger-based data transfer. When the operational mode changes (active to power-saving or vice versa), the system automatically initiates the appropriate data transfer between memories without requiring external intervention or complex coordination protocols. This self-service mechanism simplifies the overall system architecture while achieving power optimization
Solution Approach 2:
The system uses feedback from operational mode status to control data transfer operations. The mode change triggers a feedback loop that automatically initiates the appropriate data migration between primary and secondary memory. This feedback-based control simplifies coordination by using the existing mode state information to drive memory management decisions, reducing the need for additional complex coordination mechanisms
3Reliability
If multiple configuration types (memory, antenna, RF front end, encoding) are dynamically managed, then signaling accuracy and throughput are improved, but device complexity increases
Solution Approach 1:
The system segments configuration management into distinct, independent modules: memory configuration, antenna configuration, RF front end configuration, and encoding configuration. Each configuration type can be independently optimized and managed based on operational mode requirements. This segmentation allows complex configuration management to be broken down into manageable, independent components that can be controlled separately, improving signaling accuracy without overwhelming system complexity
Solution Approach 2:
The system implements a universal configuration management framework that handles multiple configuration types (memory, antenna, RF front end, encoding) through a common operational mode-based control mechanism. This multi-functional approach allows a single set of mode-change triggers to coordinate all configuration types simultaneously, improving signaling accuracy across all components while avoiding the need for separate complex management systems for each configuration type
Data Source
AI summary
This disclosure provides methods, components, devices and systems for device coordinated dynamic configuration management for high reliability communication. Some aspects more specifically relate to techniques to coordinate the transfer of data between primary and secondary memories of a device such as an access point (AP) for communication with a wireless station (STA). The AP may be capable of storing data in a directly accessible primary memory, and in a secondary memory, which may be inaccessible until the data in the secondary memory is transferred to the primary memory. In some aspects, the AP may dynamically transfer data based on changes in one or more operating modes of a STA. The AP may transfer data from the secondary memory to the primary memory in accordance with the STA entering an active mode, or from the primary memory to the secondary memory in accordance with the STA entering a power saving mode.
