Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the receiver estimates channel quality information by all reception antennas or codes in parallel, then the estimation accuracy is improved, but the device complexity and processing burden increase
Solution Approach 1:
The patent segments the channel quality estimation process by dividing all reception antennas or codes into multiple groups. Instead of processing all antennas/codes simultaneously, the receiver divides them into separate groups and performs estimation on each group independently, reducing the processing burden while maintaining comprehensive coverage of all antennas/codes.
Solution Approach 2:
The patent applies partial action by selecting and processing only a subset of reception antennas or codes at each estimation instance. Rather than requiring all antennas/codes to be processed in parallel, the system performs multiple partial estimations on different subsets, achieving comprehensive channel quality assessment with reduced per-instance complexity.
2Device complexity
If the receiver serially estimates channel quality information by all reception antennas or codes, then the device complexity is reduced, but the estimation time increases
Solution Approach 1:
The patent segments the estimation process into multiple independent groups of antennas or codes that can be processed in parallel. By dividing the total set into manageable segments, the system achieves parallel processing capability without requiring full simultaneous processing of all elements, thus reducing overall estimation time while keeping individual processing tasks manageable.
Solution Approach 2:
The patent performs multiple partial estimations on different subsets of antennas or codes simultaneously through parallel processing. Each partial estimation processes a subset, and the results are combined to form the complete channel quality assessment, achieving faster overall estimation compared to sequential processing.
3Productivity
If the receiver reduces the estimation time for channel quality information, then the productivity is improved, but the measurement precision deteriorates
Solution Approach 1:
The patent segments the channel quality estimation into multiple independent groups that can be processed in parallel. This segmentation allows the receiver to maintain high processing speed by utilizing parallel computation resources while ensuring that each segment receives sufficient processing attention to maintain accuracy.
Solution Approach 2:
The patent performs multiple partial estimations on different subsets of antennas or codes in parallel, achieving comprehensive channel quality assessment faster than sequential processing would allow. The combination of multiple partial results provides accurate overall estimation without requiring extended processing time.

AI summary
A method and device for processing channel quality information in a communication system is provided. A preset sampling range is determined to estimate a channel quality of a sub-frame in a quality measurement mode. The sampling rate is calculated based on the interval between samples in the channels of the sampling range. The samples are detected in the channels according to the sampling rate. The channel quality information is measured in the samples. A receiving apparatus can maintain the cannels for measuring the channel quality information, i.e., the number of samples, in a certain range. The receiving apparatus can reduce the number of samples, thereby reducing the time required for measuring the channel quality information by a preset measurement time interval. The receiving apparatus can increase the number of samples, thereby raising the accuracy of the channel quality information.
