Adaptive Common Control Signal Duplication in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies due to the high resource overhead from transmitting duplicate common control signals across the entire cell coverage area, which reduces network capacity and throughput.
Innovation Solution
Adaptive duplication of common control signals in time or frequency, determined by the network based on the presence and capabilities of user equipment (UEs) within the cell, allowing for reduced duplication where unnecessary, thereby optimizing resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common control signals are duplicated across the entire cell coverage area, then all UEs can receive the signals, but resource overhead increases and network capacity decreases
Solution Approach 1:
The patent applies local quality by transmitting common control signals only in specific local areas where UEs are actually present, rather than duplicating signals across the entire cell coverage area. The network node determines the location of UEs and transmits signals targeted to those specific locations, reducing resource overhead while maintaining reliable signal reception for all relevant UEs.
Solution Approach 2:
The patent implements dynamics by making the signal transmission adaptive to changing conditions. The network node dynamically adjusts signal transmission based on UE presence, capabilities, and locations. When UEs move or new UEs connect, the transmission pattern changes accordingly, optimizing resource usage while ensuring all UEs can receive necessary control signals.
2Area of stationary object
If common control signals are transmitted with high power over entire coverage area, then signal coverage is improved, but energy consumption increases
Solution Approach 1:
The patent applies local quality by concentrating transmission energy only in the specific geographic locations where UEs are present, rather than distributing high power transmissions across the entire cell coverage area. This targeted approach maintains adequate signal coverage for all UEs while significantly reducing total energy consumption.
Solution Approach 2:
The patent implements partial action by transmitting control signals only in the portions of the coverage area where UEs are actually located, rather than providing excessive coverage throughout the entire cell area. This reduces energy consumption while maintaining sufficient coverage for all relevant UEs.
3Adaptability or versatility
If control signals are transmitted on all frequency resources, then all UEs can access signals, but available network throughput decreases
Solution Approach 1:
The patent applies local quality by allocating control signal transmissions to specific frequency resources based on UE locations and capabilities. Different frequency resources are used in different spatial locations, allowing efficient spectrum utilization while ensuring all UEs can access appropriate control signals for their specific context.
