Carrier Aggregation Configuration for Spectrum Emission Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in determining the appropriate spectrum emission requirements for carrier aggregation, particularly in scenarios where different frequency bands require different emission modes.
Innovation Solution
A method and apparatus for transmitting and receiving configuration information that allows mobile terminals to determine the appropriate additional spectrum emission mode based on indicated carrier aggregation types, such as intra-band contiguous or non-contiguous carrier aggregation, by using configuration messages from network devices.

Engineering Contradiction Analysis
1Reliability
If a single configuration message is used for all carrier aggregation types, then device complexity is reduced, but spectrum emission compliance cannot be met for different carrier aggregation scenarios
Solution Approach 1:
The configuration message is segmented into multiple independent fields, each corresponding to a specific carrier aggregation type (intra-band contiguous, intra-band non-contiguous, inter-band). Each field contains the spectrum emission requirement specific to that aggregation type, allowing the terminal to select and apply the appropriate configuration based on the actual aggregation scenario without increasing overall device complexity.
2Reliability
If different spectrum emission requirements are specified for different carrier aggregation types, then emission compliance is improved, but information transmission overhead increases
Solution Approach 1:
The configuration message structure implements local quality by providing differentiated spectrum emission requirements only where needed - each carrier aggregation type field contains specific emission parameters applicable to that aggregation scenario. The terminal selectively processes only the relevant field corresponding to its current aggregation type, avoiding unnecessary information processing and reducing effective overhead despite the comprehensive structure.
3Productivity
If the terminal determines spectrum emission mode autonomously, then network signaling overhead is reduced, but determination accuracy decreases
Solution Approach 1:
The network performs preliminary action by pre-calculating and configuring the appropriate spectrum emission requirements for each carrier aggregation type in the configuration message. The terminal then autonomously selects the correct pre-configured parameters based on its current aggregation type, combining network-side preparation with terminal-side autonomous selection to achieve both accuracy and signaling efficiency.
