Solution Overview
Problem
Existing communication systems face challenges in ensuring proper timing for control operations across multiple communication nodes due to delays in backhaul lines, which can lead to irregular control information acquisition and potential misalignment in control actions among nodes.
Innovation Solution
A communication control system that includes a control entity and an execution entity, which measure and collect backhaul quality information to adjust the application of control schemes such as interference control and CoMP transmission and reception, ensuring optimal timing and resource allocation based on backhaul line quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information is transmitted through backhaul lines between multiple communication nodes, then coordinated transmission and reception can be achieved, but delays and irregularities in backhaul lines cause timing misalignment and control information acquisition deviations
Solution Approach 1:
The patent applies preliminary action by measuring backhaul quality in advance before control information transmission. The communication control device obtains backhaul quality information regarding delays and irregularities, then uses this pre-acquired information to determine appropriate transmission timing and control parameters, compensating for expected delays before they occur.
Solution Approach 2:
The patent implements feedback by continuously monitoring backhaul line quality and using this information to adjust control timing. The communication control device obtains backhaul quality information and uses it to determine transmission timing, creating a closed-loop system that adapts to changing backhaul conditions to maintain synchronization.
2Ease of operation
If control schemes are applied without considering backhaul quality, then control operations can be simplified, but timing irregularities and delays cause misalignment in control actions among nodes
Solution Approach 1:
The patent applies parameter changes by adjusting control timing parameters based on measured backhaul quality. The communication control device obtains backhaul quality information and determines transmission timing accordingly, dynamically changing timing parameters to compensate for backhaul delays and irregularities while maintaining operational simplicity.
3Reliability
If backhaul quality measurement and adaptation mechanisms are implemented, then control timing accuracy is improved, but system complexity increases due to additional measurement and control functions
Solution Approach 1:
The patent applies universality by designing a communication control device that performs multiple functions: backhaul quality measurement, quality information acquisition, timing determination, and control information transmission. This multi-functional approach consolidates what could be separate complex systems into a unified device, reducing overall system complexity while maintaining high timing accuracy.
