Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern communication systems face challenges in efficiently conveying antenna configuration information due to significant bandwidth requirements, leading to overhead issues in wireless communication systems.
Innovation Solution
The method involves encoding antenna configuration information into a QPSK constellation or error correction data, allowing base stations to transmit this information without separate transmission, using techniques like QAM and CRC masking to reduce overhead while ensuring reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna configuration information is transmitted separately, then detection reliability is improved, but communication overhead increases
Solution Approach 1:
The patent combines antenna configuration information with existing data transmission by embedding it in the PBCH message. Instead of separate transmission, the configuration data is merged into the broadcast channel, reducing overhead while maintaining detection reliability through integrated error correction coding.
Solution Approach 2:
The PBCH message serves multiple functions: it transmits general system information and simultaneously conveys antenna configuration information. This multi-functionality eliminates the need for dedicated separate transmission channels for configuration data, reducing overall communication overhead.
2Quantity of substance
If antenna configuration information is embedded in data stream, then communication overhead is reduced, but detection reliability deteriorates
Solution Approach 1:
The patent applies error correction coding before embedding the antenna configuration information in the data stream. This preliminary error protection cushioning ensures that even when the information is embedded and potentially more susceptible to errors, the detection reliability is maintained through the pre-applied error correction mechanisms.
Solution Approach 2:
Error correction codes act as an intermediary that protects the embedded antenna configuration information. The coding scheme mediates between the reduced overhead requirement and the need for reliable detection, allowing the information to be embedded while maintaining integrity through the error correction layer.
Data Source
AI summary
Reliable detection of the configuration of transmit antennas includes obtaining a data for transmission, encoding the data, and modulating the data. During the modulating of the data, the data may be configured in such a way as to convey the configuration of the antennas through the modulation of the data. An antenna configuration is obtained by obtaining a representation of the antenna configuration, and masking the data with an error correcting code, where the mask corresponds to the antenna configuration.
