Solution Overview
Problem
Current wireless communication devices face challenges in improving transmission characteristics and maintaining stable demodulation when frequency bandwidth and time slots are adjusted, especially when the sending device is idle for a period, leading to loss of series information and incorrect data reception.
Innovation Solution
A wireless communication device that sends and receives data in resource block units, using a transmission control data separation unit to separate resource-dependent and resource-independent data, and performs error correction and puncture processing to ensure consistent transmission control data format across all resource blocks, facilitating easy demodulation and stable reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the frequency bandwidth is widened and time slot is expanded to improve transmission characteristics, then the data transmission capacity is improved, but the processing complexity increases and multiple channel decodings are required
Solution Approach 1:
The transmission control data is segmented into resource-dependent data and resource-independent data. The resource-independent data is replicated across multiple resource blocks, while resource-dependent data is specific to each resource block. This segmentation allows the receiver to process each resource block independently with consistent formatting, reducing overall processing complexity while maintaining high data transmission capacity.
Solution Approach 2:
The patent changes the parameter structure of transmission control data by separating it into two distinct types (resource-dependent and resource-independent). This parameter change enables consistent data formatting across different resource block sizes and configurations, allowing the system to handle varied bandwidth and time slot allocations without increasing processing complexity.
2Ease of manufacture
If the same transmission control data is sent at the same wireless sending bit regardless of resource allocation, then the implementation is simple, but transmission characteristics are not improved when frequency bandwidth is widened or time slot is expanded
Solution Approach 1:
The patent applies local quality by making transmission control data adaptive to local resource conditions. Resource-dependent data varies according to the specific resource block configuration (frequency bandwidth, time slots), while resource-independent data remains consistent. This allows transmission characteristics to be optimized for each specific resource allocation while maintaining implementation simplicity through the structured separation of data types.
3Loss of energy
If the sending device does not perform sending for a certain period, then energy consumption is reduced, but known series information is lost in the reception device causing incorrect data reception
Solution Approach 1:
The patent implements preliminary action by having the sending device transmit known series information (preamble or synchronization signals) before actual data transmission after a period of inactivity. This preliminary transmission refreshes the reception device's reference information, ensuring accurate demodulation and decoding of subsequent data while allowing the system to remain in a low-power state during idle periods.
