Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of communication channel design and user reception, along with heavy signaling overhead, are challenges in traditional LTE systems, particularly in 5G systems where flexible multiplexing of control and data channels is needed to improve resource utilization.
Innovation Solution
A method for transmitting control information that involves specifying a transmission mode with a predetermined relationship to the data channel, including parameter configurations such as Cyclic Prefix length, OFDM symbol length, and Subcarrier Spacing, to enable flexible and effective multiplexing, reducing channel design complexity and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flexible multiplexing of control and data channels is implemented in 5G systems, then resource utilization is improved, but channel design complexity and user reception complexity increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting multiplexing parameters (TDM/FDM modes, resource block allocations, symbol assignments) based on channel conditions and traffic requirements. This allows the system to optimize resource utilization while managing complexity through adaptive parameter selection rather than fixed complex structures.
Solution Approach 2:
The patent implements dynamics by enabling the control channel and data channel to switch between different multiplexing modes (TDM and FDM) dynamically based on system conditions. This dynamic adaptability improves resource utilization efficiency while allowing the system to simplify to appropriate modes when conditions permit, thereby managing complexity.
2Productivity
If flexible multiplexing of control and data channels is implemented in 5G systems, then resource utilization is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiplexing patterns and resource allocations that can be activated based on pre-agreed rules between base station and terminal. This reduces the need for extensive real-time signaling, as many decisions are made in advance based on predetermined configurations rather than requiring continuous detailed signaling.
Solution Approach 2:
The patent implements self-service by enabling terminals to autonomously determine their reception parameters based on pre-configured rules and available information, rather than requiring the base station to explicitly signal all parameters. This self-determination capability reduces signaling overhead while maintaining flexible resource utilization.
3Ease of manufacture
If TDM multiplexing is used for control and data channels, then implementation is simple, but resource utilization efficiency decreases
Solution Approach 1:
The patent applies dynamics by allowing the system to switch between TDM (simple implementation) and FDM (better resource utilization) multiplexing modes based on system conditions and requirements. This enables the system to achieve simple implementation when using TDM while improving resource utilization when switching to FDM, resolving the contradiction through adaptive mode selection.
