CBRS Channel Prioritization for Carrier Aggregation Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bandwidth of the Citizens Broadband Radio Service (CBRS) band does not support optimal carrier aggregation capabilities for all devices, necessitating mechanisms to dynamically allocate additional component carriers and channels to enhance throughput and communication efficiency.
Innovation Solution
A self-organizing network system dynamically assigns CBRS devices to boost and normal channel device groups, allocating dedicated channels exclusively to the boost group to optimize carrier aggregation and communication quality.

Engineering Contradiction Analysis
1Productivity
If the CBRS band allocates spectrum space to all devices without channel orthogonalization, then spectrum utilization is maximized, but carrier aggregation capabilities cannot be optimized for all devices
Solution Approach 1:
The CBRS devices are segmented into two distinct groups: boost channel device group and normal channel device group. This segmentation allows different channel allocation strategies to be applied to different device groups, enabling optimized carrier aggregation for boost group devices while maintaining overall spectrum utilization efficiency.
Solution Approach 2:
Different quality levels of channel allocation are applied locally to different device groups. The boost channel device group receives enhanced local quality through dedicated channels and optimized carrier aggregation, while normal channel device group receives standard allocation, allowing each group to operate at its appropriate performance level.
2Productivity
If additional component carriers are allocated to boost channel device group, then throughput is increased for eligible devices, but bandwidth availability for other devices is reduced
Solution Approach 1:
The channel allocation is made dynamic through uplink grants that can be adjusted based on device eligibility and network conditions. The base station can dynamically allocate additional component carriers to boost group devices when needed while maintaining flexibility to reallocate resources when conditions change, ensuring optimal throughput enhancement without permanent bandwidth loss.

AI summary
Systems, methods, and computer-readable media for dynamically assigning devices to specific channels in the CBRS band. One or more dedicated channels within the CBRS band can be selected and a boost channel device group can be formed by exclusively allocating the one or more dedicated channel to the boost channel device group. Further, a normal channel device group can be formed by allocating, to the normal channel device group, one or more channels in the CBRS band that are separate from the one or more dedicated channels allocated to the boost channel device group. One or more devices communicating in the CBRS band can be selectively assigned to either the boost channel device group or the normal channel device group to selectively control communications in the CBRS band over the one or more dedicated channels utilized by the boost channel device group.
