Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless multi-hop communication systems, conventional beamforming methods are inefficient due to high signalling overhead and latency, which impacts link throughput and network performance, especially with user mobility and varying traffic patterns.
Innovation Solution
A control device generates a composite beam control signal that includes antenna beam control information for multiple communication nodes along a communication path, allowing for efficient beamforming with reduced signalling overhead by using orthogonal code sequences and phase shift information, enabling fast beam direction adjustments without the need for multiple beam control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate beam control signals are transmitted to different communication nodes, then each node receives accurate beam control information, but the signalling overhead and latency increase
Solution Approach 1:
The patent combines multiple beam control signals intended for different communication nodes into a single composite beam control signal. This composite signal contains beam control information for multiple nodes encoded together, reducing the number of separate transmissions needed while maintaining the accuracy of beam control information for each individual node.
Solution Approach 2:
The composite beam control signal serves multiple functions simultaneously by providing beam control information to multiple communication nodes through a single signal transmission. This multi-functional approach allows one signal to replace what would traditionally require multiple separate signals, reducing overhead and latency.
2Measurement precision
If multiple separate beam control signals are transmitted to different communication nodes, then each node receives accurate beam control information, but the signalling overhead increases
Solution Approach 1:
The patent merges multiple beam control signals into a single composite signal that carries beam control information for multiple communication nodes. This consolidation reduces the quantity of signalling data that needs to be transmitted across the network while preserving the precision of control information for each node through proper encoding schemes.
Solution Approach 2:
The patent employs parameter changes in the signal encoding domain by using orthogonal code sequences and phase shift information to encode multiple beam control messages within a single composite signal. This allows the system to transmit more information efficiently by changing the parameter space in which data is encoded, reducing the overall signalling overhead.
3Productivity
If fast beamforming is implemented for multiple communication nodes, then network throughput and capacity improve, but the system complexity increases
Solution Approach 1:
The patent performs preliminary encoding of beam control information for multiple nodes into a composite signal before transmission. By pre-processing and combining the control information in advance, the system enables fast beamforming responses without requiring complex real-time processing at each communication node, thus improving throughput while managing system complexity.
Solution Approach 2:
The patent uses orthogonal code sequences as a form of coding copy mechanism, where each communication node's beam control information is represented through unique orthogonal codes within the composite signal. This allows nodes to extract their specific control information through correlation operations, enabling fast beamforming with reduced computational complexity compared to transmitting full beam control data to each node.
