Signaling Carrier Bandwidth Combinations via Bitmap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of carrier bandwidth combinations in wireless communication networks for carrier aggregation poses a significant implementation and testing burden, as only a subset of these combinations is of commercial interest, leading to potential interference issues when new bandwidths are enabled.
Innovation Solution
User Equipment (UE) signals supported carrier bandwidth combinations, simplifying testing and operation by indicating specific combinations, using methods such as bitmaps or indices, to reduce the burden of extensive testing across all possible permutations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all possible carrier bandwidth combinations are tested, then reliability is improved, but device complexity and testing burden increase significantly
Solution Approach 1:
The patent extracts only the commercially relevant carrier bandwidth combinations from the complete set of possible combinations. By identifying and testing only this subset, the solution maintains reliability for practical deployments while significantly reducing testing burden and complexity.
Solution Approach 2:
Instead of performing exhaustive testing of all possible carrier bandwidth combinations, the patent applies partial action by testing only the necessary subset that is of commercial interest. This approach achieves sufficient reliability for practical purposes without the excessive burden of complete testing.
2Adaptability or versatility
If new bandwidth combinations are enabled, then adaptability is improved, but interference issues arise from untested bandwidths
Solution Approach 1:
The patent enables new bandwidth combinations only after they have been pre-tested and validated. This preliminary testing ensures that adaptability is improved while preventing interference issues from untested bandwidths, as all enabled combinations have already been verified for proper operation.
3Ease of operation
If comprehensive carrier bandwidth combinations are supported, then ease of operation is improved, but loss of time increases due to extensive testing
Solution Approach 1:
The patent extracts only the commercially relevant carrier bandwidth combinations from the complete set. This reduces testing time significantly while maintaining ease of operation for practical deployments, as only the necessary combinations need to be tested and supported.
Solution Approach 2:
The patent applies partial action by testing only the subset of carrier bandwidth combinations that are of commercial interest. This achieves sufficient configuration flexibility for real-world operations while avoiding the time loss associated with exhaustive testing of all possible combinations.

AI summary
Techniques for signaling carrier bandwidths supported by a user equipment (UE) for carrier aggregation are disclosed. A UE may be configured with a plurality of carriers for carrier aggregation. Each carrier may have one carrier bandwidth of a set of possible carrier bandwidths. The set of possible carrier bandwidths may be dependent on a band in which the carrier belongs. Multiple combinations of carrier bandwidths for the plurality of carriers may be possible. The UE may identify at least one supported carrier bandwidth combination for the plurality of carriers. Each of the supported carrier bandwidth combinations may include a particular carrier bandwidth for each configured carrier. The UE may send signaling indicative of the at least one supported carrier bandwidth combination, wherein the signaling comprises a bitmap of a plurality of bits for a plurality of available carrier bandwidth combinations for the plurality of carriers. The UE may thereafter communicate on the plurality of carriers based on a carrier bandwidth combination selected from the supported carrier bandwidth combination(s).
