Fallback Bandwidth Classes for Flexible Component-Carrier Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular communication technologies, as defined by 3GPP standards, restrict carrier aggregation channels to non-overlapping bandwidths, leading to inefficient utilization of allocated bandwidth.
Innovation Solution
Allocating aggregated channel bandwidth classes for a fallback group that overlap in frequency, allowing for more flexible use of component carriers to fully utilize the available bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If carrier aggregation channels are restricted to non-overlapping bandwidths as per 3GPP standards, then channel organization is simplified and standardized, but bandwidth utilization efficiency deteriorates
Solution Approach 1:
The patent segments the carrier aggregation bandwidth classes into multiple subsets, where each subset contains bandwidth classes with non-overlapping frequency ranges. This allows the system to maintain standardized non-overlapping organization within each subset while enabling overlapping across different subsets, thereby resolving the contradiction between organizational simplicity and utilization efficiency.
Solution Approach 2:
The patent introduces a new dimension of organization by creating multiple subsets of bandwidth classes. Instead of a single flat structure, the system now has a hierarchical structure with subsets as the first dimension and bandwidth classes within subsets as the second dimension. This allows overlapping bandwidth classes to be organized in a structured manner that maintains both simplicity and efficiency.
2Productivity
If aggregated channel bandwidth classes overlap in frequency, then bandwidth utilization efficiency is improved, but system complexity increases
Solution Approach 1:
By segmenting bandwidth classes into multiple subsets where each subset maintains non-overlapping frequency ranges, the patent reduces the complexity of managing overlapping bands. The segmentation allows the system to leverage the simplicity of non-overlapping organization within subsets while achieving overall bandwidth efficiency throughè·¨-subset overlapping.
Solution Approach 2:
The patent changes the organizational parameter from a single flat structure to a multi-subset hierarchical structure. This parameter change allows the system to maintain manageable complexity within each subset while achieving superior overall bandwidth utilization through the coordinated use of multiple subsets with overlapping frequency ranges.

AI summary
Aggregated channel bandwidth classes that overlap in frequency are allocated for a fallback group. The fallback group may define an increased or maximum bandwidth of aggregated component carriers as allocated by a network. By enabling the aggregated channel bandwidth classes for a fallback group to overlap in frequency, for an available aggregated channel bandwidth, a first aggregated channel bandwidth class may be implemented using a first number of component carriers, and a second aggregated channel bandwidth class may be implemented using a second number of component carriers different from the first. The different number of component carriers may enable more flexibility to more fully utilize the available aggregated channel bandwidth for communication. The network may then allocate one of these aggregated channel bandwidth classes to user equipment that more fully utilizes the available aggregated channel bandwidth for communication.
